AGS2602 TVOC Sensor Based On MEMS Principle Module For Applied To Air Purifiers

Product Introduction:

The AGS2602 is a TVOC sensor based on MEMS principle, which is used to monitor the concentration of small - range VOC gases. It has the characteristics of low power consumption, high sensitivity, low cost, and a simple driving circuit. The sensor is pre - calibrated and tested before leaving the factory to meet the large - scale application requirements of customers.

Working Principle:

The sensor adopts advanced MEMS technology to fabricate a micro - hot - plate on a silicon - based substrate. The gas - sensitive material is a metal oxide semiconductor material with low electrical conductivity in clean air. When the sensor works in an air environment, the electrical conductivity of the gas - sensitive material changes with the concentration of the detected gas in the air. The higher the concentration of the detected gas, the higher the electrical conductivity of the gas - sensitive material. Based on this principle, a dedicated integrated circuit is used to convert the change in electrical conductivity into an output signal corresponding to the gas concentration.

Application Fields:

It is suitable for monitoring the concentration of various TVOC gases, such as ethanol, ammonia, sulfides, benzene - series vapors, smoke, and other harmful gases. It can be applied to air purifiers, household appliances, fresh - air systems, and other equipment.
