Arduino and MQ-2 (gas & smoke) sensor

Hooking up an MQ-2 (gas & smoke) sensor to an Arduino Uno via a breadboard. The wiring connection is important: Both A pins and the left H pin need to be connected to 5V. Both B pins need to be connected to the analog input (A0). The right H pin needs to be connected to the ground (GND). A load resistor from 2kOhm to 47kOhm needs to be ...

Me Gas Sensor(MQ2) - STEAM Projects | Makeblock

· Detection principle: MQ-2 type of smoke sensor adopts stannic oxide as the semiconductor gas sensitive material which is the surface ionic N-type semiconductor. When the temperature is in the range of 200~300℃, the stannic oxide adsorbs the oxygen in the air to form into negative oxygen ions, so that the electron density of the semiconductor is decreased and its resistance is increased. When ...

Air Quality Sensor | MySensors Forum

· During the weekend I did the hardware changes and tried my MQ-2 sensor again and now if I hit it with smoke (I have smoke on a can) I do get values in Vera under the Variable1 property. No values on the dashboard device itself. I guess some changes are needed for the device file to display the V_VAR1 or we should use something else than V_VAR1. If you have already updated the sketch for the MQ ...
