Slim Node as a Mini 2AA Battery PIR Motion Sensor
-
@ awi, so i desolderd and bridged the two mentioned components, and with the standard " Motion Detector " sketch it transmits tripped readings now :)
I power the circuit via a UNO ( 3,3Volt) or via 2 AA batterys ( 3,1 Volts -> meassured via multimeter)but when using the given sketch in this thread only battery readings are transmitted...

Hello, when running the "Motion Detector sketch from the mysensors-examples" on these nodes with the 1Mhz bootloader with 2aa batteries some nodes freeze after appr. 24h .
Some continue working, i cant find the problem.
Does anybody have a idea what could cause those freezes ?
Thanks in advance -

No, i didnt put the additional sleep in , where should I put this ?

I meant like this (look in code below), but it's just a wild guess.

@m26872 said in Slim Node as a Mini 2AA Battery PIR Motion Sensor:
Removing the 7133-regulator did not affect anything significantly due to its very low quiescent current (see datasheet, perhaps useful in some other project?)
ok, does that mean one does not have to remove the voltage regulator and the diode? @AWI is saying one must modify the PIR and now I am irritated...
-
@siod
I removed both to make the smaller ( HC-SR505 ) work with ~3Volt and bridged these contacts as shown in the picture
They work perfectly fine for me and are not too sensitive.
Actually they dont even react on my cats, which is nice, because the "bigger" HC-SR501 always did... :) -
And with the "bigger" HC-SR501 all one need to do is obviously to connect the VCC to the pad or pin.
For me at least it is working pretty fine as well. No false positives or anything else negative.
Of course you have to remove the jumper first.

That was only regarding the power consumption. I don't remember the voltage drops but I guess you'll get to it work with 2AA but for a shorter time. Why wont you remove them?

ok guys, I tried the mini PIR and the big one, on the mini PIR I removed the regulator and diode just as explained and I uploaded this sketch

I am having the exact same issues with the Mysensor2.0 version ... (!)
When using Arduino IDE 1.65 and Mysensor 1.54 librarys and the sketch that is pinned in the header it works .
@Komaandy @siod
Did you try version 2.2 as in https://forum.mysensors.org/topic/6511/hc-sr501-3-3v-randomly-sends-tripped-when-radio-is-on/36 ? -
Nope, 2.2 is giving me the same fail trip messages.
When using IDE 1.6.5 with 1.5.4 I don´t even get it compiled, Arduino is automatically using 2.2.0 library from 1.8.2 version which is, of course, still installed on my system and I don´t want to uninstall it...edit: Ok, the way @komaandy proposed is working, though I like the other sketch more...
edit2: Well, seems like it has sth. to do with the battery sensing: when removing this part from void loop() it works as it is supposed to (see what I commented out between /* and */):
void loop() { //Batterysensor // get the battery Voltage /*int sensorValue = analogRead(BATTERY_SENSE_PIN); #ifdef DEBUG #endif int batteryPcnt = sensorValue / 10; gw.sendBatteryLevel(batteryPcnt); gw.wait(500); gw.send(msgbatt.set(batteryPcnt)); gw.wait(500); */ if (interruptReturn) { // Woke up by rising pin gw.send(msg.set("1")); // Just send trip (set) commands to controller. (Let controller reset and decide what to do with it.) irtCounter++; } gw.sleep(3000); // Make sure everything is stable before start to sleep with interrupts. (don't use "gw.wait()" here). Tests shows false trip ~2s after battery report otherwise. // Sleep until interrupt comes in on motion sensor or sleep time passed. interruptReturn = gw.sleep(MOTION_INPUT_PIN-2,CHANGE, ONE_DAY_SLEEP_TIME); // DEBUG_PRINT("interruptReturn: ");DEBUG_PRINTLN(interruptReturn); }edit3: I obviously mixed up things, now it seems like it´s working... I will report back after some time of testing, but this should be my working code:

I know this is an old topic, but it seems tried and true, so.. How is everyone's experience with this design sofar? Has it been reliable? How far has the 24 month battery life claim held up?
I've been looking for a detection node that I could use for various tasks around the house (Motion detect, reed switch detect, even a simple door bell). But with a plain arduino pro mini I keep running into abysmal battery life. However this setup seems to handle a year on some AA batteries quite easily?
If I can get some confirmation on the reliability on these, I can pull the trigger on producing a handful of these slimnodes. ;)

@Sven-0
Fun to see this old topic again. And also the coincidence, since my visits here have been rare for a long time. :disappointed:
Anyway, I'm running a few slimnodes since the beginning and have both good and bad experiences. In general, the battery lifetime is your least concern. Instead I have had issues with sensors, sensitivity, switch contact corrosion, mechanical robustness, wifi interference, repaeter, gateway, controller, waf, kids, animals, etc, etc.
Regarding this particular PIR slimnode it's very stable, but it is not universal for every situation due to the limited range and missing sinsitivity adjustment. E.g I can't use it too near my basement windows due to the moving cold air. And in my living room I have sun reflections to deal with.
I suggest you start by building a testnode to check if it works for your conditions.:slot_machine:
