Product Description:
GM-802B GM802B Ammonia NH3 Gas Sensor Is Used For Refrigerator Gas Detection Of Ammonia leaks In Cold Storage
Features:
MEMS ammonia gas sensor is composed of a MEMS process SI-based micro-hot plate and a metal oxide semiconductor material with low conductivity in clean air. When there is a detected gas in the ambient air, the conductivity of the sensor changes. The higher the concentration of the gas, the higher the conductivity of the sensor. A simple circuit can be used to convert the change in conductivity into an output signal corresponding to the concentration of that gas.
Product advantage
GM-802B ammonia gas sensor adopts MEMS technology, strong structure, high sensitivity to ammonia; It has the advantages of small size, low power consumption, high sensitivity, quick response recovery, simple drive circuit, good stability and long life.
Main application
It is widely used in refrigerator gas detection, ammonia leakage in cold storage and risk control system of agricultural breeding.
