Developed “SMH-01B01”, Thermopile-type Infrared
Array Sensor Module with 8 x 8 elements

SEIKO NPC Corporation (HQ: Chuo-ku, Tokyo, President: Hiroaki Okawa) has developed thermopile-type infrared array sensor module with 8 x 8 elements “SMH-01B01”, miniaturized by mounting Si-lens optical system for far infrared radiation, detection circuit and control MCU on a single board.

This module is equipped with a COB(chip on board) sensor IC and an Si-lens optical system, and features an MCU with built-in A/D converter that generates digital output, on an I2C interface, of both the converted emission temperature of each sensor element and the ambient temperature. The module also has a built-in 20 to 200 variable gain preamplifier which enables measurement of wide temperature range using auto range control by software.

Compared with existing sensors, advantages of this module are high output sensitivity and wide range of temperature detection that satisfy the needs of electronic and industrial equipments(air-conditioner, medical equipment, automobile, etc.).
