Presenting MQ sensors: lowcost gas and pollution ...

Feb 16, 2018· In order to verify that our choice was a valid one, we then had to correlate the readings we carried out as regards the MH14Z NDIR (Non Dispersive Infrared Sensor) sensor, having a +5ppm resolution in the 0÷2000ppm CO 2 range; you will find an excerpt in figure. The reference sensor is an infrared operating one.


how mq 2 sensor zone works

MQ2 Semiconductor Sensor for Combustible Gas. Structure and configuration of MQ2 gas sensor is shown as Fig. 3, sensor composed by micro AL2O3 ceramic tube, Tin Dioxide (SnO2) sensitive layer, measuring electrode and heater are fixed into a crust made by plastic and stainless steel net.


Configure and read out the Raspberry Pi gas sensor (MQX)

Connection between MQ2 and Raspberry Pi. In this example, we use a 5V voltage as output. This is too much for the GPIOs, which is why we use a logic level converter (TTL) that cuts down the voltage. If you use a sensor other than the MQ2 and it has a different voltage, the setup must of course be adjusted.
