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℃ , and The accuracy is ±(2.0% + 2℃) Specifications Voltage:3.3 ~ 5V Max power rating at 25℃ :300mW Operating temperature range:-40 ~ +125 ℃ The temperature measurement range is (-50 ~ +600℃) Amplifier output voltage range (0 ~ 3.3 V) mv Cold junction compensation (environment temperature measurement) Thermocouple temperature measurement accuracy of + / - 2.0% (+ 2 ℃) Package Include: Grove - High Temperature Sensor x1 Thermocouple Temperature Sensor x1 24AWG Grove Cable - 4P-4P-2.0-200mm x1 Documents Wiki Grove - High Temperature Sensor PDF Grove - High Temperature Sensor Eagle File High Temperature Sensor Library
