Rain Guage

[petewill]

@BulldogLowell Did you ever get around to updating the sketch to work with version 1.4.1? I'm finally getting around to making a rain gauge and I didn't want to recreate the wheel if you already made it and I missed it somewhere.

Thanks,

Pete

@petewill

Sorry for the lag time, I've been on Easter vacation with the family!

Yes, I did update it, but I don't have my laptop with me here. I'll post it when I return home, early next week.

[petewill]

@BulldogLowell Great, thanks! You are a way better coder than me and I was struggling to understand the code. I did learn quite a bit about interrupts when I was trying to figure it out though.

[petewill]

@BulldogLowell Any luck finding the sketch? Sorry to bug you, I was just hoping to get this project completed soon so I can work on the irrigation controller next. It's almost time to start watering the lawn/plants... Thanks!

@petewill
I am embarrassed to tell you that after updating my arduino software a while back, I cannot locate a compilable sketch!

I have Time Machine, but still can't find it... and it is running on my rain guage!!!

Here is a version that I have (which is titled RainGuage_V1.4.1.ino in my directory) which i found but cannot compile, it looks like a first save without edit?

I need to completely update Arduino, the version and mySensors but please look at this:

 Arduino Tipping Bucket Rain Gauge
 
 June 15, 2014
 
 Version 1.00b   
 
 Arduino Tipping Bucket Rain Gauge
 
 Utilizing a tipping bucket sensor, your Vera home automation controller and the MySensors.org 
 gateway you can measure and sense local rain.  This sketch will create two devices on your 
 Vera controller.  One will display your total precipitation for the last 24, 48, 72, 96 and 120
 hours.  The other, a sensor that changes state if there is recent rain (up to last 120 hours) 
 above a threshold.  Both these settings are user definable. 
 
 This sketch features the following:
 
 * Allows you to set the rain threshold in mm  
 * Allows you to determine the interval window up to 120 hours.
 * Displays the last 24, 48, 72, 96 and 120 hours total rain in Variable1 through Variable5
   of the Rain Sensor device
 * Configuration changes to Sensor device updated every 3 hours.
 * SHould run on any Arduino
 * Will retain Tripped/Not Tripped status and data in a power outage, saving small ammount
   of data to EEPROM (Circular Buffer to maximize life of EEBPROM
 * There is a unique setup requirement necessary in order to properly present the Vera device 
   variables.  The details are outlined in the sketch below.
 * LED status indicator

Her is an untested go at it, and a very down and dirty update... I will test it probably Wednesday night, when I am back home. Let me know if you can!

@BulldogLowell Awesome, thank you very much! I know what it's like to lose code that way. I have done the same thing myself...

Yes, I will test this. I'll do my best to get it tested tonight. I'm combining it with some other sensors (light and temp/humidity) so once I get everything merged I'll be able to upload it.

I'll let you know what I find.

Thanks again!

Ok, I made the necessary changes for my application and I had a couple of questions along the way.

• I have never worked with eeprom so I don't pretend to know anything about it (it's now on my list of things to research though). Anyway, I noticed above hek recommended using the "saveState()/loadState() function in the MySensors library". Is that necessary in your code or are we ok as is? It seems to be functioning ok for me when I compile it so maybe not...

• I would like to trigger my rain sensor as soon as the first bucket has tipped (I have scenes that tell me to close the windows etc. when it's raining). Is changing the rainSensorThreshold value to 1 an appropriate way to do that or should I create another child node for my purposes? Maybe I should use rainRate in my PLEG instead?

• My tipping bucket was pulled from an existing rain gauge and according to my calculations (which may be off) each bucket is .7mm of rain. I don't know much about unsigned long variables but I'm wondering if I need to change "const unsigned long calibrateFactor" to a float or something?

Thanks for all your help!!

Jim,

I uploaded the code but it didn't seem to work for me. Do I need to upload some additional files to Vera? When I added the nodes a lot of my devices stopped displaying correctly (not just the newly added ones). They look like this:

When I deleted the rain gauge nodes everything came back:

As I was looking at the code I came up with some additional questions:

• There is a dayBuckets array but it doesn't seem to do anything in the code?

• I also couldn't find "const unsigned long calibrateFactor" used anywhere.

I fully admit I'm not a very good with code and I could be missing something. I was just trying to find how the variables were working together and being calculated.

Thanks for all your help with this! I could not do it without you.

@petewill The reason your MySensor plugin brakes when you add the rain gauge is that the device_files are missing. I don't know if there are any device files for the rain gauge since they are not included in the github branch for the vera plugin.

You could check under your rain gauge which device_file it is trying to use maybe you can search for it online and hope it exists.
Worst case is that you need to create them your self.

yeah, you need the implemention files:

As I was looking at the code I came up with some additional questions:

There is a dayBuckets array but it doesn't seem to do anything in the code?

I also couldn't find "const unsigned long calibrateFactor" used anywhere.

dayBuckets[] was used in the old code and since I designed 1mm of rain per tip, I never had to implement calibration.

I have never worked with eeprom so I don't pretend to know anything about it (it's now on my list of things to research though). Anyway, I noticed above hek recommended using the "saveState()/loadState() function in the MySensors library". Is that necessary in your code or are we ok as is? It seems to be functioning ok for me when I compile it so maybe not...

I developed the code before hek integrated EEPROM in his libraries. This uses a circular buffer, so it would take me some time to reprogram for hek's library, so I just kept using the arduino EEPROM.h library I used to develop the original code.

@petewill said:

changing the rainSensorThreshold value to 1 an appropriate way to do that

yes, I hardcoded boundaries, which you will will allow a minimum of 1 (one)

@petewill said:

My tipping bucket was pulled from an existing rain gauge and according to my calculations (which may be off) each bucket is .7mm of rain. I don't know much about unsigned long variables but I'm wondering if I need to change "const unsigned long calibrateFactor" to a float or something?

Sorry, I never put a bucket calibration into my code, I lucked out with the 1mm per tip working.

[petewill]

@BulldogLowell Thanks for the responses! Ok, I suspected I was missing some implementation files. Thanks for them. Did you create them from scratch? If so, nice!

I will take a look at the code to see if I can implement the calebrateFactor. I will most likely be back with more questions. :) Thanks again.

[petewill]

@BulldogLowell
I have been doing lots of research and working to understand the code so it will work with the calibrateFactor and I have another question... Why is the "tipSensorPin" set to OUTPUT then INPUT? Does that have to do with the interrupt?

pinMode(tipSensorPin, OUTPUT);
attachInterrupt (1, sensorTipped, CHANGE); //* should this be RISING instead??
pinMode(ledPin, OUTPUT);
digitalWrite(ledPin, HIGH);
gw.sendSketchInfo(SN, SV);
gw.present(CHILD_ID_RAIN, S_RAIN);
gw.present(CHILD_ID_TRIPPED_RAIN, S_MOTION);
Serial.println(F("Sensor Presentation Complete"));
pinMode(tipSensorPin, INPUT);

Thanks again for your help! I'll post the full code back here when I have it working in case anyone else wants to use a different size tipping bucket.

it looks a lot like a bonehead error in the code!!

funny how the brain works, I never noticed that...

@BulldogLowell said:

Ok, thanks. I make those constantly...

I have been testing the code for the last couple of days and I think this is working but another set of eyes would be good. I added functionality to set the "calibrateFactor" to a decimal. I also updated the save/load EEPROM to work with the MySensors standard. It seems to be working in my testing but I'm no programmer.

I also have two questions:

1. Is it necessary to save/load "state" to/from EEPROM? It seems that from my testing the state is set when "measure" is calculated in this line: state = (measure >= rainSensorThreshold);. It seems that measure is evaluated when the sensor first loads and rainBucket [] is loaded from EEPROM. Hopefully that makes sense what I'm asking.

2. I'm still trying to understand interrupts but I'm wondering if changing to "FALLING" would be more appropriate? Maybe it doesn't matter but I thought I'd check. Here is the line I'm referring to: attachInterrupt (1, sensorTipped, FALLING);

Here is the code if you wanted to take a look:

 Arduino Tipping Bucket Rain Gauge
 
 April 26, 2015

 Version 1.01b for MySensors version 1.4.1

 Arduino Tipping Bucket Rain Gauge

 Utilizing a tipping bucket sensor, your Vera home automation controller and the MySensors.org
 gateway you can measure and sense local rain.  This sketch will create two devices on your
 Vera controller.  One will display your total precipitation for the last 24, 48, 72, 96 and 120
 hours.  The other, a sensor that changes state if there is recent rain (up to last 120 hours)
 above a threshold.  Both these settings are user definable.

 This sketch features the following:

 * Allows you to set the rain threshold in mm
 * Allows you to determine the interval window up to 120 hours.
 * Displays the last 24, 48, 72, 96 and 120 hours total rain in Variable1 through Variable5
   of the Rain Sensor device
 * Configuration changes to Sensor device updated every 3 hours.
 * SHould run on any Arduino
 * Will retain Tripped/Not Tripped status and data in a power outage, saving small ammount
   of data to EEPROM (Circular Buffer to maximize life of EEPROM)
 * There is a unique setup requirement necessary in order to properly present the Vera device
   variables.  The details are outlined in the sketch below.
 * LED status indicator

This starts to look really good. Maybe we should lift this into the examples on github?

Just wish someone could sell the tipping bucket hardware. :)

@petewill

Pete, let me look it all over again and see if we can get the calibration working. I think the EEPROM part can be updated for @hek 's addition into the mySensors library.

@hek maybe we can do a 100% printed design for the collector/funnel and mechanism. and offer that on github as well.

Good idea. We could probably just place the stl-file in the folder together with ino-file. Let me know when you feel ready.
