The TGS2444 gas sensor from Figaro utilises a multilayer sensor structure with a tin dioxide (SnO2) sensing layer. A simple electrical circuit can be used to convert the change in conductivity to an output signal proportional to gas concentration. The device displays good selectivity to ammonia, making it suitable for critical safety-related applications such as the detection of ammonia leaks in refrigeration systems and ammonia detection in the agricultural field.
• Compact PCB mounting sensor. • Low power consumption. • High sensitivity and selectivity to ammonia (NH3)
Gases Detected = Ammonia
Application = Ammonia Leak Detection in Refrigerators, Poultry Industries, Ventilation Control for The Agricultural
