MQ gas and air quality sensors - Olimex

In this example, we would use SNS-MQ2. Yet, a sensor alone can't provide us with any information about the air. The sensors described in the previous chapter would not work in stand-alone mode. They lack a general-purpose microcontroller. They need a host board to send data to. The host board would also provide power to the sensors.

Configure and read out the Raspberry Pi gas sensor (MQ-X)

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, MQ-135, etc.) can also be adapted with a few additional steps. Accessories. All MQ-X sensors return analogue signals, which we can not easily read at the Raspberry Pi.

DHT11 - Humidity and Temperature Sensor

DHT11 - Humidity and Temperature Sensor The DHT11 is a basic, low-cost 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.
