MQ2 Gas Sensor User Manual 1. Features Sensitive gas Liquefied gas, propane and hydrogen Boost converter chip PT1301 Operating voltage Dimensions * Fixing hole size Operating principle: MQ2 gas sensor applies SnO2 which has a lower conductivity in the clear air as a gassensing material. In an atmosphere where there may be inflammable gases, the …
DHT11 Humidity and Temperature Sensor The DHT11 is a basic, lowcost digital temperature and humidity sensor. It uses a capacitive humidity sensor and a thermistor to measure the surrounding air, and spits out a digital signal on the data pin (no analog input pins needed). Its fairly simple to use, but requires careful timing to grab data. The only real downside of this sensor is you can ...
How to configure any MQ sensor and read it out with the Pi will be shown on the example of the Raspberry Pi gas sensor MQ2 in this tutorial. All other sensors (MQ3, MQ135, etc.) can also be adapted with a few additional steps. Accessories. All MQX sensors return analogue signals, which we can not easily read at the Raspberry Pi. One possibility would be to use an Arduino, but we can also …
