Thermo K Click Board

Product Description

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.

APPLICATION

Hand-held measurement equipment, industrial equipment thermal management, petrochemical thermal management, etc.

SPECIFICATIONS

The Thermo K Click Board™ carries the  MCP9600 IC from Microchip  and and depending on the type of probe it uses, the click can measure temperatures from −200 °C to +1372 °C. The Thermo K Click Board™ is designed to run either on 3.3V or 5V power supply. It communicates with the target MCU through I2C interface.

Pinout Diagram

This table shows how the pinout on the Thermo K Click Board™ corresponds to the pinout on the mikroBUS™ socket (the latter shown in the two middle columns).
