Saiya Sensor SY-TP-36BPDG

SY-SRT0113 is a digital thermopile sensor with I²C readout interface that measures object temperature without direct contact. The thermopile chip is fabricated using MEMS technology, connecting hundreds of thermocouple pairs in series. The thermopile absorbs infrared energy emitted by the target object and, based on the Seebeck principle, outputs a corresponding voltage to detect the target temperature. The sensor operates over an ambient temperature range of -20°C ~ +85°C with a measurement temperature range of -20 ~ +250°C, enabling a wide range of applications. The I²C interface allows various applications to communicate with the device.
