Arduino mini pro 3.3 battery optimization code
-
Dear All!
I would like to use the Arduino Mini Pro 3.3 8Mhz (aTMega328) with 2xAA battery. I have read that it useful to put it in powerdown/sleep mode.
Could you help me what code/sketch should I use. I copied to here my beta sketch(It works, but it doesnt have the powerdown function)
If someone has any other suggestion related to the code, please write it!/** * The MySensors Arduino library handles the wireless radio link and protocol * between your home built sensors/actuators and HA controller of choice. * The sensors forms a self healing radio network with optional repeaters.

sleep(SLEEP_TIME);
That is the power down command, usually it is put at the end of loop
-
@tommas - have a look at the build section: https://www.mysensors.org/build/battery
-
Oh ok. I have put this in the code, so it is OK, i think. I thought that SLEEP_TIME isnt equal to powerdown, but it seems that i misunderstood.
I use your easypcb board Sundberg.... Is your battery measurement code better than this standard mysensors one?Thank You again!
-
Dear Gohan!
Thank you! I thought that it isnt equal with this: https://www.mysensors.org/download/sensor_api_20#sleeping ....
But perhaps I misunderstood something because you says that it is the same sleep mode...
-
SLEEP_TIME is defined as the amount of time the node will sleep, but it is the function sleep() that actually puts the node into low power mode and that usually is at the end of loop
-
@tommas - "my" batterycode is due to a booster and a voltage divider. Its not possible to compare this to @Yveaux Vcc library which uses the internal vcc to measure battery level. This is not possible to use since you boost your VCC on the arduino. I think my code works great though for a voltage divider setup.
-
Hi All!
Im near to get it work:) .
Someone could write an example openhab2 thing and item for Battery Voltage handling?Thank you!

Sorry, I'm revisiting a temp/hum sensor running on battery, I lost my code so I'm back to work with this (and signing/encryption, doh!)
I think I have something similar to yours- I'm boosting the arduino and DHT voltage to 3,3v, while the antenna is directly connected. I have a voltage divider where I get the Voltage measure. Can I borrow directly your code, you think?
-
@ghiglie - you can, as long as you have the same divider... (which is the standard divider found @ mysensors website.)

Dear All!
Can I use 2xAA 1.6V NiZn battery for 3.3V arduino mini pro?
Accoding to wikipedia, at 100% SOC each cell would deliver 1.85V, which is a smidge too high if running the pro mini with its voltage regulator removed. Well, actually, the pro mini would tolerate it, just maybe not the radio.
-
@tommas get some LiFePo4 AA and you can use a single cell
-
Dear @neverdie ,
Ok, so I wont use these batteries.
-
I did a new code, and it seems that it is do the job.
My goal was, that I only send the battery voltage (percent) when:
At least one of sensor value transmission occured + The battery report time is elapsed.What do you think about my code? IT IS NOT ONLY MY CODE and it is not clear yet Thank for @gohan , @sundberg84 and mysensors for the base.

If you measure current while the node is sleeping, if it is in the range 6 to 20 uA you are good

What kind of sleep is it? There are parameters out there. ADC_OFF and some and some... Is this sleep turn off adc?
-
Just use the sleep () function, that's it
-
Ok! After the "loop ended " the node should go to sleep. On the console I see these lines:
Loop ended
62763 MCO:SLP:MS=300000,SMS=0,I1=255,M1=255,I2=255,M2=255
62773 MCO:SLP:TPDWhat does it mean?
