Product Overview
The SL-FW-TRS-5.5D1/N1 series is a high-precision digital output differential infrared thermopile sensor developed for non-contact temperature measurement. It features high infrared response rate, high repeatability, and high reliability, housed in a TO-39 metal can package. The integrated MEMS thermopile sensor chip and a professional signal conditioning ASIC chip, which includes a 24-bit Sigma-Delta ADC, low-noise PGA, interface circuits, and a high-precision thermistor for ambient temperature compensation, enable direct digital temperature output without external circuitry or user calibration. This sensor is ideal for long-distance body temperature measurement, smart home appliances, industrial temperature monitoring, and intelligent temperature sensing and control applications, with a measurement distance of 30-50 cm.
