The SL-W-TRS-5.5Dx series are high-precision digital output differential infrared thermopile sensors designed for a wide range of non-contact temperature measurement products and industries. These sensors integrate a MEMS thermopile sensor chip, an NTC thermistor, and a professional signal conditioning ASIC chip. The ASIC features a 24-bit Sigma-Delta high-precision ADC, a low-noise PGA, and interface circuitry. The series comprises six models (D1 to D6), combining a base sensor (D1) with a base sensor and optical cup, suitable for temperature measurement applications in products like medical devices, smart wearables, and electronic sentinels.
