Rain Guage

[mrc-core]

Which resistor do i pu between the 5v and the D3 pin ???

[BulldogLowell]

@mrc-core

if you don't pull up/down the signal, you may get floating voltages and spurious interrupts occurring.

try to use the internal pullup

pinMode(yourInterruptPin, INPUT_PULLUP);

if that does not work try an external 10kOhm resistor to pull it up/down for your switch.

[mrc-core]

Going to put the 10kOhm resistor. the internall pullup did not work.
One question. the resistor i put it between de 5v and the D3 pin

[BulldogLowell]

@mrc-core

to PULL UP, yes.

[mrc-core]

Thanks going to try it now. And today is a good day since its raining.

No luck... now i'm getting only "0"

What i have done until now:
Put a resistor 10kOhm between the GND and D3 Pin from arduino and connect it to TX2 over rthe rain gauge.
And connected the 5V from arduino to the VCC over the rain gauge.

But i'm only getting 0 ...

@mrc-core

I guess I'd need to see a schematic or a good photo.

can you generate a simple interrupt with a pushbutton and a resistor?

[mrc-core]

Hi. yesterday i disassembled the rain gauge circuit removed from it the reed switch and created a new circuit.
I have connnected the reed switch to GND and PIN3 whit 10kOhm resistor.
I'll post an image tonight.

Up until now the values i'me getting from this new circuit is:

Values i'm getting from serial port:
Rain last 24 hours:
1.80
Rain last 48 hours:
12481.94
Rain last 72 hours:
28210.34
Rain last 96 hours:
43938.74
Rain last 120 hours:
59667.14
read and drop: 6-6-255 s=255,c=3,t=7,pt=0,l=0,sg=0:
read and drop: 6-6-255 s=255,c=3,t=7,pt=0,l=0,sg=0:
read and drop: 5-5-255 s=255,c=3,t=7,pt=0,l=0,sg=0:
read and drop: 6-6-255 s=255,c=3,t=7,pt=0,l=0,sg=0:

Seeing the graphic and this values it seems the problem i was having is fixed...
But tonight i'm going do spread some water over the bucket to see if i get any values and not just 0

MI-SOL Rain Guage has CALIBRATE_FACTOR = 36

[Ivan Z]

Sensor manufacturer has sent information about the sensor. 0.3 mm to 1 tick

[petewill]

@Ivan-Z :thumbsup: Thanks for the info.

[Theekshana]

Hey guys,
Sorry if this is a stupid question but how does the Arduino interact with the tipping bucket to detect rain?
Thanks!

[petewill]

@Theekshana There is a magnet on the tipping bucket and a reed switch that detects the magnet each time it passes by. So each time the bucket tips it will trigger to the Arduino and it can count from there.

Has anyone converted this sketch to Mysensors 2.0 already? I've tried but received following error when compiling:

/*
 Arduino Tipping Bucket Rain Gauge

 April 26, 2015

 Version 1.4.1 alpha

 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 5 days.  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.

 There is a build overview video here: https://youtu.be/1eMfKQaLROo

 This sketch features the following:

 * Allows you to set the rain threshold in mm
 * Allows you to determine the tripped indicator window up to 120 hours.
 * Displays the last 5 days of rain in Variable1 through Variable5
   of the Rain Sensor device
 * Configuration changes to Sensor device updated every hour
 * Should run on any Arduino
 * Will retain Tripped/Not Tripped status and data in a power interruption, saving small amount
   of data to EEPROM (Circular Buffer to maximize life of EEPROM)
 * LED status indicator
 * Optional Temp/Humidity (DHT-22 or DHT-11) and Light LUX (BH1750) sensors. To use, uncomment
   #define DHT_ON  and/or #define LUX_ON
 * Optionally send total accumulation of each day's rainfall or send only individual days rainfall totals.
   Comment out #define USE_DAILY to display individual daily rainfall.

@niccodemi syntax for time functions is:

requestTime();						// Request latest time from controller

// This is called when a new time value was received
void receiveTime(unsigned long controllerTime) {

@AWI thank you. Sketch compiles now but after uploading it still doesn't work - serial monitor is blank (debug on).

Using the new code for version 2.0.0 i'm getting this errors:

 Arduino Tipping Bucket Rain Gauge

 April 26, 2015

 Version 1.4.1 alpha

 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 5 days.  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.

 There is a build overview video here: https://youtu.be/1eMfKQaLROo

 This sketch features the following:

 * Allows you to set the rain threshold in mm
 * Allows you to determine the tripped indicator window up to 120 hours.
 * Displays the last 5 days of rain in Variable1 through Variable5
   of the Rain Sensor device
 * Configuration changes to Sensor device updated every hour
 * Should run on any Arduino
 * Will retain Tripped/Not Tripped status and data in a power interruption, saving small amount
   of data to EEPROM (Circular Buffer to maximize life of EEPROM)
 * LED status indicator
 * Optional Temp/Humidity (DHT-22 or DHT-11) and Light LUX (BH1750) sensors. To use, uncomment
   #define DHT_ON  and/or #define LUX_ON
 * Optionally send total accumulation of each day's rainfall or send only individual days rainfall totals.
   Comment out #define USE_DAILY to display individual daily rainfall.

It compiles fine with Arduino IDE 1.6.5, Mysensors 2.0.0 and libraries (Time, BH1750).

Yes that's the one.

Using IDE 1.6.5 i get this:

@mrc-core Remove folder "Time" from your libraries folder, then download the "MySensorsArduinoExamples" zip from this link and extract Time library to your libraries folder. Restart Arduino IDE and try again.
