With the continuous development of intelligent life, intelligent home, robot, intelligent equipment has been widely used in life.These applications also include a variety of functional sensors, which respond by sensing to the center of the device.Among them, the more common sensors are gas sensors and particulate sensors. What are the commonly used gas sensors and particulate sensors?

Gas sensor:

Common sensors used for atmospheric monitoring include carbon monoxide (CO), carbon dioxide (CO2), nitric oxide (NO), nitrogen dioxide (NO2), sulfur dioxide (SO2), volatile organic compounds (VOCs), ozone (O3), smog, etc.

Common sensors used in indoor monitoring include general air quality sensors, formaldehyde (HCHO), total volatile organic compounds (TVOC), etc.

Public toilets, farms commonly used sensors, including hydrogen sulfide (H2S), ammonia gas (NH3) and so on.

Common flammable toxic sensors, including hydrogen cyanide (HCN), phosphine (PH3), arsenic (ASH3), acrylonitrile (C3H3N), ethylene oxide (ETO) and so on.

Common combustible sensors include combustible gas, methane (CH4), hydrogen (H2), oxygen (O2), etc.

Toxic common sensors, including chlorine (CL2), phosgene (COCL2) and so on.

Other sensors commonly used in industry include chlorine dioxide (CLO2), fluorine gas (F2), hydrogen bromide (HBr), hydrogen chloride (HCL), hydrogen fluoride (HF), sulphur hexafluoride (SF6), silane (SIH4), tetrahydrothiophene (THT), methanethiol (CH3SH), etc.

The principles of gas sensors above are commonly used in four categories, namely: infrared principle, electrochemical principle, catalytic combustion principle and photoion principle.

Particulate matter sensor:

Particulate matter sensors commonly used include PM10 sensors and PM2.5 sensors, and sensor principles commonly used include laser principle and infrared principle.It is worth noting that for different levels of use, application environment, accuracy requirements, range requirements, etc., the selection of particulate matter sensors is also different.

Selection of particulate matter sensor is recommended: GDS06 infrared PM2.5 particulate matter sensor, infrared principle measurement, long service life, high cost performance.
