Description

The CJMCU-96 module integrates the Microchip Technology MCP9600 IC, a complete thermocouple signal conditioner and analog-to-digital converter. It performs cold junction compensation internally using an onboard temperature sensor, eliminating the need for external reference junctions and ensuring accurate readings across the full –40 °C to +125 °C operating range. The device digitizes the thermocouple’s millivolt output with high resolution and linearity.

Designed for system flexibility, the module features programmable digital filtering to suppress noise in electrically noisy environments, such as industrial control panels or motor drives. Its I2C communication protocol allows for easy daisy-chaining of multiple sensors, while four configurable alarm outputs can trigger interrupts or control external systems based on user-defined temperature thresholds. The wide 2.7V to 5.5V supply range ensures compatibility with both 3.3V and 5V logic systems.

Key Features

  • High-precision thermocouple-to-digital converter with integrated signal conditioning.
  • Broad compatibility with eight standard thermocouple types (K, J, T, N, S, E, B, R).
  • Onboard cold junction compensation sensor for accurate ambient temperature measurement.
  • Configurable digital noise filtering for stable readings in industrial environments.
  • Four independent, programmable temperature alarm outputs with hysteresis.
  • Low quiescent current (500 μA typical) supports battery-powered or energy-sensitive applications.
  • Standard I2C serial interface with selectable addresses for multi-sensor systems.
  • Robust operating temperature range from –40 °C to +125 °C for harsh conditions.

Applications

  • Industrial process control and equipment temperature monitoring (furnaces, extruders, reactors).
  • Laboratory and scientific instrumentation requiring multi-channel thermocouple data acquisition.
  • Embedded system integration for HVAC, energy management, and thermal protection circuits.
  • Prototyping and development platforms (Arduino, Raspberry Pi, ESP32) for temperature sensing projects.
  • Battery-powered portable data loggers and environmental monitoring stations.

Frequently Asked Questions

What thermocouple types does the CJMCU-96 MCP9600 module support?

The module supports eight standard thermocouple types: K, J, T, N, S, E, B, and R, in full compliance with the NIST ITS-90 standard. It automatically applies the correct linearization and cold junction compensation algorithms for each type via its internal configuration registers.

What is the input voltage range and how do I power this module?

The module operates from a single supply voltage between 2.7V and 5.5V DC, making it compatible with both 3.3V and 5V microcontroller systems like Arduino, Raspberry Pi, and ESP32. Connect the positive supply to the VCC pin and ground to GND. Ensure your power source can provide stable voltage to avoid measurement noise.

How do I connect multiple CJMCU-96 modules to a single microcontroller?

The module uses an I2C interface with three user-selectable address pins (A0, A1, A2). By setting the logic levels on these pins (high or low), you can assign one of eight unique I2C addresses, allowing up to eight modules to share the same SDA and SCL bus lines from a single microcontroller.

Does the module require calibration or external components for cold junction compensation?

No, the MCP9600 IC integrates a precision temperature sensor for cold junction compensation directly on the chip. The module performs all necessary compensation internally, so no external components or manual calibration of the reference junction is required for basic operation, simplifying system design.
