Mailbox/Postbox Alert
-
@Moshe-Livne just deactivate the this lines:
//digitalWrite(MAILBOX_FRONT_PIN, HIGH);
//digitalWrite(MAILBOX_BACK_PIN, HIGH);and solder two resistor from 3.3v to pin 2 and 3.

Ok, so I found that it is the radio that draws about 7mA when I ground input pin 2, it is connected to IRQ-pin on the radio.
@n3ro Have you connected the radio as described on the build-page? [http://www.mysensors.org/build/connect_radio](link url) -
I'm guessing that your repeat() function is wearing out the battery.
By the way you can take advantage of the return of sleep( ) here:
gw.sleep(MAILBOX_FRONT_PIN - 2, CHANGE, MAILBOX_BACK_PIN - 2, CHANGE, 0);like this (untested):
#include <MySensor.h> #include <SPI.h> #include <readVcc.h> #define NODE_ID 21 // ID of node #define CHILD_ID 1 // Id of the sensor child #define MAILBOX_FRONT_PIN 2 // Arduino Digital I/O pin for button/reed switch #define MAILBOX_BACK_PIN 3 // Arduino Digital I/O pin for button/reed switch #define MIN_V 1900 // empty voltage (0%) #define MAX_V 3200 // full voltage (100%) MySensor gw; MyMessage msg(CHILD_ID, V_TRIPPED); boolean post = false; boolean lastpost = false; int oldBatteryPcnt; int repeat = 20; int trigger = -1; unsigned long goToSleepTime; void setup() { gw.begin(NULL, NODE_ID, false); pinMode(MAILBOX_FRONT_PIN, INPUT); pinMode(MAILBOX_BACK_PIN, INPUT); digitalWrite(MAILBOX_FRONT_PIN, HIGH); digitalWrite(MAILBOX_BACK_PIN, HIGH); gw.sendSketchInfo("Mailbox Alert", "1.0"); gw.present(CHILD_ID, S_MOTION); Serial.println("---------- set Mailbox empty"); msg.set(0); } void loop() { if (millis() - goToSleepTime > 10UL) //debounce { switch (trigger) { case 0: post = true; Serial.println("---------- New Mail"); break; case 1: post = false; Serial.println("---------- Mailbox emptied"); break; default: Serial.println("---------- I just woke up"); } } trigger = -1; if (post != lastpost) { Serial.print("---------- Send Mailboxstate "); Serial.println(post ? "full" : "empty"); msg.set(post); lastpost = post; sendBattery(); } // Sleep until something happens with the sensor goToSleepTime = millis(); trigger = gw.sleep(MAILBOX_FRONT_PIN - 2, CHANGE, MAILBOX_BACK_PIN - 2, CHANGE, 0); } void sendBattery() // Measure battery { int batteryPcnt = min(map(readVcc(), MIN_V, MAX_V, 0, 100), 100); if (batteryPcnt != oldBatteryPcnt) { gw.sendBatteryLevel(batteryPcnt); // Send battery percentage oldBatteryPcnt = batteryPcnt; } Serial.print("---------- Battery: "); Serial.println(batteryPcnt); }@BulldogLowell could you please explain your changes? I don't understand everything of this :sweat:

@n3ro Ok, thanks! Then I learned something new today.. IRQ is only needed for receiving nodes then, like repeaters and gateways, right?
Strange though that my circuit draws so much more current than yours. I have tested different setups, different arduinos and different radios from different suppliers with same result.
Well, at least my mailbox are mysensored now! :smiley: -
Nope, havent done that yet. It´s a "stock" 3v3 pro mini. Still reading up on how to do that and how to change to MYS-bootloader, curious on how OTA-update works.
Big thanks for your respons! :smile: -
@f1dev sweebe wrote a very good howto:

@n3ro Brilliant! He recommends to take out the voltage regulator. it is easier (and works better) just to snip off one leg as described here http://www.mysensors.org/build/battery. I'll try his other mods.... hopefully now my nodes will last forever!!!!

quality project, been having a tinker with mixed results. used sketch from original post, but would it be possible to get a circuit diagram showing pull up locations??? bit of a beginner, but have had a few success with rolling out some power operated sensors , this is my first battery operated sensor...

thanks for the diagram, much appreciated...

Hello,
Does this code still work?
Thank you
