This Grove-Infrared temperature sensor is a non-contact temperature measure model.The sensor is composed of 116 elements of thermocouple in series on a floating micro-membrane having an active diameter of 545μm and with blacken surface to absorb the incident thermal infrared radiation, which induces a voltage response at output terminals.

Great below 30C ambient, inaccurate if sensor is hotter The voltage divider used to measure the ambient temperature uses a 2M resistor. The thermistor is only 100k and on a 12 bit ADC the accuracy degrades quickly if the thermistor gets hotter than about 30C.
