Hello guys,
Watch out newbee on the road
.
Im looking for the correct settings how to connect the MQ2 smoke sensor to Domoticz. I've wired the following way:
ESP - MQ2
GND - GND
VIN - VCC
AD0 - A0
For the ESPEASY settings i've used the following:
Device: Gases CO2 Senseair
Sensor: Carbon Dioxide
1st and 2nd GPIO none (also tested with 1st GPIO set at GPIO2 (D4))
At the IDX i've set the sensor id in Domoticz
After testing with a flame and smoke nothing happens in ESPEASY, value stay's 0.
Ive tested the whole path (from sensor - esp to domoticz) with a HC-SR04 and worked within a few seconds.
What im missing in the whole plan?
For your info: my Domoticz platform is running on a RPI 3B.
Kind regards.
