3 in 1 incl battery monitor

I just finished my first motion sensor node and the power consumption in idle is about 75uA. Could be better but not too bad ;)
The only thing is that the range is a little bit low for good detection. It's between 1 and 3 meters ...David.

Hello David
Could you share what and how ? :)
Thnx

Hello,
This is the code I use but it's not perfect especially with the battery report.
The principle is as follow when the sensor start:
- node in sleep mode with interrupt enable
- if a move is detected, the detection is reported to the gateway
- the node then go in sleep mode WITHOUT interrupt for 5 minutes
- then the node return to sleep mode with interrupt enable
This is to avoid having many report (and power consumption) to the gateway.
The code (not perfect ! I have to rework on it but it's ok for the moment):
/** * 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. Each * repeater and gateway builds a routing tables in EEPROM which keeps track of the * network topology allowing messages to be routed to nodes. * * Created by Henrik Ekblad <henrik.ekblad@mysensors.org> * Copyright (C) 2013-2015 Sensnology AB * Full contributor list: https://github.com/mysensors/Arduino/graphs/contributors * * Documentation: http://www.mysensors.org * Support Forum: http://forum.mysensors.org * * This program is free software; you can redistribute it and/or * modify it under the terms of the GNU General Public License * version 2 as published by the Free Software Foundation. * */ /**************************************************************************************/ /* Motion sensor. */ /* */ /* Version : 1.1.5 */ /* Date : 30/01/2016 */ /* Modified by : David Carlier */ /**************************************************************************************/ /* --------------- */ /* RST | | A5 */ /* RX | | A4 */ /* TX | ARDUINO | A3 */ /* RFM69 (DIO0) --------- D2 | UNO | A2 */ /* Motion --------- D3 | | A1 */ /* Power --------- D4 | ATMEGA 328p | A0 */ /* +3v --------- VCC | | GND --------- GND */ /* GND --------- GND | 8MHz int. | REF */ /* OSC | | VCC --------- +3v */ /* OSC | | D13 --------- RFM69 (SCK) */ /* D5 | | D12 --------- RFM69 (MISO) */ /* D6 | | D11 --------- RFM69 (MOSI) */ /* D7 | | D10 --------- RFM69 (NSS) */ /* D8 | | D9 */ /* --------------- */ /* */ /* +3v = 2*AA */ /* */ /**************************************************************************************/ #include <SPI.h> #include <MySensor.h> #include <MyTransportRFM69.h> #include <MySigningAtsha204Soft.h> //Constants #define SKETCH_NAME "Motion Sensor" #define SKETCH_VERSION "1.1.5" #define CHILD_ID 0 #define CHILD_ID_VOLTAGE 1 #define DIGITAL_INPUT_SENSOR 3 #define BATTERY_REPORT_CYCLE 4 //Report each hour (4 * 15') //Misc. variables uint8_t switchState = 2; unsigned long SLEEP_TIME = 820000; // Sleep time between reads (in milliseconds) (close to 15') unsigned long SLEEP_TIME2 = 275000; // Sleep time after int.

Working correctly for the moment (one month) but it depends on the presence in the house.

@ Carlied,
What code is better that one of you or the one from cosmi gate?
What are the different thing? Is your code check'the battery status?
And i get a error:
no matching function for call to 'MySensor::MySensor(MyTransportRFM69&, MyHwATMega328&, MySigningAtsha204Soft&)' -
The error is because I enable the signing function !
Remove the following line:MySigningAtsha204Soft signer;And replace
MySensor node(transport, hw, signer);by
MySensor node(transport, hw);I don't know who had the best sketch.
I measure internal battery status using the 1.1 reference.David.

@the-cosmic-gate Nothing special. I made a big sketch, which contains 7-8 sensors (DHT, Si7021, MQ-2/9, PIR, Door magnet, Light, battery) reading code because I would like to upload the same sketch to all nodes and configurate it on controller side, which sensors is on the node and need to read.
But currently I reached the limit with I2C includes, so I need to think over this solution.@icebob said:

Did you finish your big code.... -
Hello,
9v means that you are using a voltage regulator which probably consumes a lot of power.
Why not using AA or AAA battery directly connected to Vcc ?David

Motion and DHT needed 5volt i wash thinking..?
So 9 @ the vcc should be strong enough i was thinking.
And i do have @ the same time 3.5 for the radioAre the extern step up better than the step down on a nano?
-
The motion can be adapt to run on 3v easily (connect the Vcc to the H pad if available. You can find information on the forum). The DHT could also run on 3v. I have several nodes like that. No problem.
Can't reply for the step-up because I don't use it.David.

@ David
How long is the 3v battery running whit this option?
-
i'am back in business after the "big move" and going to try again to get this 4:1 sensor working for a long time uning 2 x AA batteries.
If someone has some new input, please let me know :) and feel free to change the sketchThere's more than meets the eye

Hello,
Motion nodes are still working correctly. The oldest node started the 4 of February is still at 3,29v. My other nodes (temp / humidity / light) are also working correctly but I will replace DHT22 for another sensor.David.
-
Hey @carlierd Just curious if you are still using a DHT22 with your sketch? Have you modified the code much from the above? I am looking at implementing something similiar ( identical actually ) and was wondering if much has changed for you over the last few months?
Thanks!
