Nice work so far @wint0178, great that you try expanding on the examples. Sorry for the late reply.
If you look at https://github.com/mysensors/MySensorsArduinoExamples/blob/bba998bce09bc5139eb4ca7a05b0279f4083ff88/examples/PressureSensor/PressureSensor.ino#L90 you see where the existing child ids are defines. You just add another one for the gas sensor, with a unique number (incrementing by 1 is an easy way).
Try that and report back on your result. If something is unclear, just post a followup.
@nono8223 I think it will be a good idea as long as there are people actively developing & supporting the platform now and in the future.
Recently the Raspberry Pi port (or Linux, in general) has been updated and included in the core library, so MySensors is no longer Arduino-only.
For those of you who want an extremely simple build, I've reduced it to just 5 parts:
one 1-megaohm resistor (0805 SMD)
one Arduino Pro Mini
one Ra-01 LoRa module
Male header pins
Battery clips
See photos.
I built a trip wire for the post box that I'm connecting. It's however based on a mercury tilt sensor so I'm really not sure whether I think it's a great idea putting it to use (at least not with a sturdy case...). However, I can share my code:
#define DIGITAL_INPUT_SENSOR 2 // The digital input you attached your motion sensor. (Only 2 and 3 generates interrupt!)
#define INTERRUPT DIGITAL_INPUT_SENSOR-2 // Usually the interrupt = pin -2 (on uno/nano anyway)
MyMessage msgTripped(CHILD_ID_TRIPPED, V_TRIPPED);
void setup()
{
gw.sendSketchInfo("Postal", "1.0");
gw.present(CHILD_ID_TRIPPED, S_MOTION);
pinMode(DIGITAL_INPUT_SENSOR, INPUT); // sets the motion sensor digital pin as input
}
void loop()
{
boolean tripped = digitalRead(DIGITAL_INPUT_SENSOR) == LOW;
if(tripped) {
gw.send(msgTripped.set("1")); // Send tripped value to gw
}
gw.sleep(INTERRUPT,FALLING, SLEEP_TIME);
}
