Feature:1. The device can convert the ambient temperature into a temperature compensation voltage through the internal temperature detection diode.2. Internally has a signal conditioning amplifier that converts the thermocouple signal into a voltage compatible with the ADC input channel3. The T and T‑inputs are connected to the low‑noise amplifier A1 to ensure the high accuracy of the detection input and at the same time isolate the thermocouple connecting wire from the interference source.4. It has 12‑bit analog/digital thermocouple converter, cold junction compensation sensing and correction, digital controller, 1 SPI compatible interface and 1 related logic control.5. The measurement temperature range is -200°C~+1350°C, the resolution is 14-bit resolution, and the accuracy is 0.25°C.Specification:Item Type: Thermocouple ModuleMaterial: PCBApplication: Detect the temperature difference between the hot and cold endsMeasuring Temperature Range: -200°C~+ 1350°CInterface Type: SPI interface, high-speed transmissionWorking Voltage: 3-5VDCResolution: 14-bit resolutionAccuracy: 0.25℃.Package List:1 x Module1 x Pin Header1 x Terminal
