Raspberry Pi 16X2 LCD Display We have another tutorial on the DHT11 for theArduinothat goes into detail on relative humidity and how the DHT11 measures it. So instead of repeating all of that here, check outHow to Set Up the DHT11 Humidity Sensor on an Arduino, then come back for the...
The sensor nodes utilize external sensor boards with sockets for accommodating the HC ultrasonic sensor and the DHT11 sensor (temperature and humidity), Grove-Gas Sensor (MQ2) (for detecting the leakage of gases that include hydrogen, liquefied petroleum gas (LPG), methane, CO, alcohol, smoke ...
MQ2 is a smoke gas sensor that uses a tin dioxide semiconductor as a gas-sensitive material. It is a surface ion-type N-type semiconductor. When it comes into contact with smoke, the smoke changes the barrier at the grain boundary, resulting in a change in the surface conductivity. The ...
