MRTD-3011 is a non-contact type digital thermopile sensor with I2C output. The thermopile chip 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. This sensor can be working in the temperature range of -10~85℃, and can measure during the range of -20~+250℃.

Application
