Product Description
Product Overview
The SL-S-TRS-5.5D1 is a digital output differential infrared thermopile sensor. It integrates a MEMS thermopile sensor chip, an NTC thermistor, and a professional signal conditioning ASIC. The ASIC features a 24-bit Sigma-Delta high-precision ADC, OTP memory, and interface circuitry. This sensor is designed for applications requiring accurate non-contact temperature measurement, such as smart wearables, smartphones, industrial temperature monitoring, and smart temperature sensing and control. Its small SMT footprint, high response rate, fast response time, and 5.5m long-pass filter window make it a versatile solution. It communicates via the I2C protocol.
