TPS2534 Dual Thermopile Sensor IC (TPS2534 Infrared Sensor)
The TPS2534 Dual Thermopile Sensor IC is a high sensitivity infrared sensing device designed for detecting thermal radiation and gas concentration using non contact measurement. It integrates two thermopile sensing elements within a single package, enabling differential measurement with a reference channel for improved accuracy. The sensor converts incident infrared radiation into a proportional voltage output using the thermoelectric effect, ensuring stable and precise detection.
The TPS2534 sensor is widely used in India for gas detection systems, NDIR gas analyzers, industrial electronics, and embedded systems. It is especially valued for its dual channel design, which allows one channel for measurement and another for reference, improving reliability and reducing environmental interference in applications such as CO2 sensing and environmental monitoring.
