3 in 1 incl battery monitor
-
What does your serial or error log tell you when you upload the sketch you have? And which sketch/code do you use at this point?
-
I'am not getting this clear / working :(
Could somebody help me to complete this 3in1 incl battery monitoring sketch working? ThnxI changed your original sketch a little. It now includes a conditional send for the "tripped" values and groups the conditional sends for all values.
I was not able to test as I'm using a different library for the DHT.
Have fun..

Thnx a lot @AWI

working nice for 2 day's now !
Thnx a lot @AWI !!! -
Something strange: when I look in the IDE console the battery % is displayed. But using Domoticz there's no battery % display / selectable ? What's wrong , or do I forget something ?
-
In Domoticz you can see the battery level in Setup->Devices.
If you would like to see on a chart, you have to send the battery level or voltage to the controller as a sensor value too. After it, you can see as this:
Hi, I'm a newbee just started with MySensors. I built the first temp/hum sensor, and I'm trying to plot the battery level in a graph too. In this discussion you mention that I need to send the battery level to the controller as sensor value. Can you please share with me the code which I should use? Thanks a lot.
Marco
-
Yes, I can.
This is the definition of message for battery level:
// Battery sensor (A0) #define CHILD_ID_BATTERY 199 #define BATTERY_SENSOR_ANALOG_PIN 0 MyMessage msgBattery(CHILD_ID_BATTERY, V_VOLTAGE);And this is the sender function:
// 1M, 470K divider across battery and using internal ADC ref of 1.1V // Sense point is bypassed with 0.1 uF cap to reduce noise at that point // ((1e6+470e3)/470e3)*1.1 = Vmax = 3.44 Volts // 3.44/1023 = Volts per bit = 0.003363075 #define VBAT_PER_BITS 0.003363075 #define VMIN 1.9 // Battery monitor lower level. Vmin_radio=1.9V #define VMAX 3.00 // Vmin<Vmax<=3.44 #define VCC_CORRECTION (3.4 / 3.33) int lastBatteryLevel; bool sendBatteryLevel(bool force = false) { int value = analogRead(BATTERY_SENSOR_ANALOG_PIN); float batVoltage = value * VBAT_PER_BITS / VCC_CORRECTION; int batLevel = static_cast<int>(((batVoltage-VMIN)/(VMAX-VMIN))*100.); if (batLevel != lastBatteryLevel || force) { gw.sendBatteryLevel(batLevel); gw.send(msgBattery.set(batVoltage, 2)); lastBatteryLevel = batLevel; } return true; }``` -
Running the sketch for 1 Monty (+-), and the AA batteries are dead empty ?
I did all the "possible" mods on the arduino ( cut the LED an V ) , what can i do to make this sketch run langer on this 2AA batteries ?
Something in the sketch , some fine tuning or something else ?
When read the arduino hardware tweaking topics on different forums they dat that running for 1 year ( and more) is possible but how ;-)? -
Hello,
Did you measured the current of your circuit ?
What motion sensor are you using ? This component may consume a lot of current. Did you check this post ?If you wake-up the arduino every 30 seconds for measurement it's a problem. Every 5 minutes is the minimum I think. I have connected the Vcc pin of the DHT sensors and the Vcc of the LDR to a digital pin of the arduino and when a measurement is done I set the PIN to the HIGH state.
First measurement of my sensor gives an IDLE current consumption close to 5uA which is really correct according to elements connected to the arduino (RFM69HW, DHT22 and LDR).

@the-cosmic-gate Now I measured my dev circuit (Arduino Nano from China (cutted power led and desoldered regulator) + DHT22 + PIR + Battery measure resistor divider) and in gw.sleep (with 1 interrupt for PIR) the power comsumption is ~90uA.
It wakes up every minutes, measuring and sending (~100ms and 5 - 20mA).
So 100ms with 20mA and 59900ms with 0.09mA. The average current is 120uA and with 2 AA battery it is about 2 years.

@ericvdb http://www.microchip.com/stellent/idcplg?IdcService=SS_GET_PAGE&nodeId=2680&dDocName=en545243. It's specified for PIC, but I select SLEEP mode in every cycle, so I can use for any uC.
@carlierd: I have no extra secret. If I measure 3-4 sensor and every values is changed, the loop time is 100ms. Best case is 10-20ms (if every sensors is unchanged). I'm not using delay in the loop.
-
@icebob: It's true that as I used signing feature, transmission is longer ! and in order to increase a little bit more I send every measure even if they not changed. I will probably upgrade my sketch to add a one-hour message at minimum and do not transfer mesure without change !

Hello David,
I tried to meassure , but didn't have the right stuff to do this good enough.
The parts i use for this "project": DHT-22 (connected to D4), HC-SR501 (connected to D3)and connected to the 3.3V pin post , the VVC is connected to the VVC of the arduino pro mini 8 Mhz /3.3 V .
And use the sketch as above:#include <SPI.h> #include <MySensor.h> #include <DHT.h> int BATTERY_SENSE_PIN = A0; // select the input pin for the battery sense point #define CHILD_ID_HUM 0 #define CHILD_ID_TEMP 1 #define CHILD_ID_MOT 2 // Id of the sensor child #define HUMIDITY_SENSOR_DIGITAL_PIN 4 #define DIGITAL_INPUT_SENSOR 3 // The digital input you attached your motion sensor.

Send update every two minute. gw.sleep(INTERRUPT,CHANGE, SLEEP_TIME); }So how do you connect the DHT / SR501 to the digital pin, and what's the sketch you're using ?

Hello,
You need to power the motion sensor all time as you want to detect any mouvement and not only every 2 minutes.
Caution, in your sketch, the battery level is sent at the beginning and at the end.
Did you tweak the motion sensor ?? Not tested yet but it seems that modification could (must ?) be done to reduce power consumption (LINK).
Why do you wake-up the arduino every 30 seconds ? For temperature, every 5 or 15 minutes is enough.
