DescriptionThermocouples 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℃ ， and The accuracy is ±(2.0% + 2℃).SpecificationsVoltage：3.3 ～ 5VMax power rating at 25℃：300mWOperating temperature range：-40 ～ +125 ℃The temperature measurement range is(-50 ～ +600℃)Amplifier output voltage range(0 ～ 3.3 V)mvCold junction compensation(environment temperature measurement)Thermocouple temperature measurement accuracy of + / - 2.0%(+ 2 ℃)Package Include：Grove - High Temperature Sensor x1Thermocouple Temperature Sensor x124AWG Grove Cable - 4P-4P-2.0-200mm x1

DescriptionFind setting up an amplifier IC on the breadboard a troublesome and totally no-need-to-repeat job? This Grove module can save you clutter to settle up such an IC by integrating the whole operating circuit. It's designed for precise differential-input amplification. Input the differential signals of your sensor to this module through the male pins， then your Arduino will get a precisely amplified output from the Grove interface. The gain scale factor is selectable. You can get a 35 times or 1085 times amplification via a switch on the board.FeaturesHigh amplifying precisionSelectable scale factorCan be conveniently read by ArduinoStrong input protection：&；plusmn；40V
