Product Details 产品规格书下载

MRT-511 thermopile sensor is based on MEMS technology, consists of hundreds of thermocouples connected in series. Using Seebeck principle, when there is a temperature difference between the target and the environment, the sensor gives the corresponding voltage output, therefore detecting the existence of the target or the temperature of the target.

 

Features

TO-46 metal package

High sensitivity

Quick response, Good stability

High filter transmittance

High precision NTC

 

Applications

Non-contact temperature measuring

Infrared thermometer, such as ear temperature and forehead temperature measurement

Continuous temperature control of production process

Household appliances (Microwave oven, hair dryers, air conditioners etc), intelligent temperature induction and control system

Human presence detection
