Thermo K Click Board
Thermo K Click Board
The Thermo K Click Board™ carries the MCP9600 IC from Microchip. Depending on the type of probe it uses the Click Board™ can measure temperatures from -200°C to +1372°C.
The Thermo K Click Board™ is designed to run either on a 3.3V or 5V power supply. It communicates with the target MCU through the I2C interface.
Temperature Range
With the Type-K Probe, available in our store, this click can measure temperature up to +480 °C. With a different probe it can theoretically measure temperature up to +1372 °C.
The Thermo K Click Board™ has a PCC-SMP thermocouple connector onboard, suitable for all K-type probes.
Microchip MCP9600
The MCP9600 IC converts thermocouple EMF to degree Celsius with integrated Cold-Junction compensation. It corrects the thermocouple nonlinear error characteristics of eight thermocouple types and outputs ±1.5°C accurate temperature data.
4 Alert Outputs
The Thermo K Click Board™ has 4 alert outputs onboard that can be used to detect multiple temperature zones. You can define on which specific temperature the THERMO K click will send an alarm.
Low Power Modes
Low-Power modes are available for battery-powered applications. In shut-down mode the module uses only 2 µA.
THERMOCOUPLE PROBE
To use the Thermo K Click Board™ you need to connect the appropriate K-type thermocouple probe (not included in the package) into the PCC-SMP connector.
Note: We offer the Thermocouple Type-K Glass Braid Insulated probes.

Software Support
The demo shows the temperature on the TFT or LCD display. It measures every half a second. We have examples for PIC, dsPIC, PIC32, ARM, AVR and FT90x compilers. The code snippet is from the Example folder of the PIC compiler and P18F87K22 MCU.
This example is a temperature reading routine. First, we are reading the “Thermocouple Temperature Register” and then we are converting the value to a temperature in the Celsius scale.
