Thermocouples are very sensitive, requiring a good amplifier with a cold - compensation reference. The Grove - Temperature Sensor USES a K type thermocouple temperature detection, with a thermistor to detect the ambient temperature as temperature compensation. The detectable range of this Sensor is -50~600'C, and The accuracy is +/-(2.0%+2'C).
Specifications:
Voltage 3.3~5V;
Max power rating at 25'C 300mW;
Operating temperature range -40~125'C;
The temperature measurement range is (-50~600);
Amplifier output voltage range (0~3.3V) mV;
Cold junction compensation (environment temperature measurement);
Thermocouple temperature measurement accuracy of +/-(2.0%+2'C).
