Saiya Sensor SY-TP-36BPDG-B

The digital thermopile sensor is an infrared thermopile temperature sensor in a TO39 package that measures the temperature of objects without direct contact. It features a built-in I2C interface for easy communication with various application interfaces. Internally, it integrates an infrared thermopile, a temperature compensation resistor, and a dedicated ASIC. Based on the Seebeck effect, the thermopile connects tens to hundreds of thermocouples in series using MEMS technology, absorbing infrared energy radiated by the target object to generate a corresponding voltage difference between the hot and cold junctions. The built-in temperature compensation resistor monitors the sensor's internal temperature in real time to achieve temperature compensation. Through algorithms embedded in the ASIC and a factory calibration process, the voltage signal is converted into a corresponding temperature signal, enabling fast and accurate target temperature detection. The sensor operates reliably across an ambient temperature range of -10℃ to +85℃, with a temperature measurement range of -20℃ to +250℃, offering broad application potential.
