Overview
NSH-424 is an infrared thermopile temperature sensor, direct contact is not required when measuring object temperature. The core component thermopile chip is formed by connecting hundreds of thermocouples in series based on MEMS technology. The thermopile absorbs the infrared energy emitted from the measured object, and uses the Seebeck theory, the sensor outputs the corresponding voltage to detect the temperature of the target.
