Environmental sensors

The MQ5 gas sensor is a metal oxide semiconductor (MOS) type gas sensor, also known as a chemiresistor. MQ5 is used to detect flammable gases such as LPG, natural gas, coal gas, and propane. The sensor has a high sensitivity to these gases, and can detect them in concentrations as low as 200 ppm.

The MQ2 Gas Sensor Module is a metal oxide semiconductor (MOS) sensor that is used to detect the presence of flammable gases and smoke. MQ2 Gas Sensor is a relatively inexpensive sensor that is easy to use and can be integrated into a variety of applications.
