DFRobot Gravity CT1780 1-Wire K-Type Thermocouple Amplifier Module (-270℃ to +1372℃) w/ Probe & Cable

The 1-Wire interface allows multiple CT1780 amplifier modules to be connected in a daisy-chain on a single microcontroller data pin. This simplifies wiring and saves I/O resources in systems requiring temperature monitoring at multiple points, such as in an industrial oven with several zones. Each module can be uniquely identified using its onboard DIP switch.

The CT1780 module operates from a DC voltage range of 3.3V to 5.5V. This makes it directly compatible with common 3.3V logic platforms like Raspberry Pi and 5V systems like most Arduino boards. Ensure your power source can provide stable voltage within this range for accurate sensor readings.

The module comes pre-calibrated and features integrated cold-junction compensation. Its specified accuracy is within ±2°C for the range of -200°C to 700°C, and within ±4°C for temperatures between 700°C and 1350°C. For most applications, no user calibration is needed, though absolute precision can be verified against a known reference if required.

No, the DFRobot CT1780 is specifically designed and calibrated for use with standard K-Type thermocouples. Using a different thermocouple type (like J, T, or E) will result in incorrect temperature readings due to differing voltage-to-temperature characteristics and the module's fixed compensation algorithm.
