Thermocouples are very sensitive temperature sensors, that can operate in quite cold and very high temperature environments. But their output signals are very small and require a good amplifier with a cold - compensation reference. The Grove - High Temperature Sensor uses a K type thermocouple, 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℃)
