WEET Resistors in Security Applications

Common resistors in security applications mainly include photoresistors and gas sensitive resistors, which are used to sense changes in light and detect gas concentration, respectively.
They are important sensor components in security equipment.

Application of photoresistors

Photoresistor, mainly used for camera infrared light board, has infrared filtering function, which can effectively suppress infrared interference and improve night shooting clarity.
Its repurchase rate reaches 18% -25%, and it is widely used in security monitoring equipment.  

Application of Gas Sensitive Resistors

Gas sensitive resistors are mainly used in gas detection sensors, such as detecting flammable or harmful gases.
Its working principle is to change the resistance value after adsorbing gas molecules through semiconductor materials, and it is commonly used in scenarios such as fire alarms and gas leak alarm devices.
