pm2.5 sensor with raspberry pi

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

Configuration of the Raspberry Pi Gas Sensor – Preparation. The concentration of a gas is given in PPM (parts per million). One difficulty of the MQ-2 is that a single analog value is given with which the gas content in the air has to be calculated for the various supported gases. However, the sensor must be configured for this purpose. Since this manual is also applicable to another Raspberry Pi gas sensor, …

50 of the most important Raspberry Pi Sensors and Components

The DS18B20 and DS18S20 represents a very simple sensor. These Raspberry Pi sensors are addressed via the so-called 1-wire bus. An advantage is that many different 1-wire components can be connected in series and read out by a single GPIO. However, these modules can not measure additional information such as humidity and / or air pressure. The ...
