T6713-5k

Overview

The T6713-5k is a non-dispersive infrared (NDIR) CO2 sensor module designed for high-accuracy air quality monitoring. It features integrated ABC Logic (Automatic Background Calibration) for long-term stability and comes factory-calibrated for a measurement range of 0 to 5000 ppm. The module supports multiple communication interfaces including I2C, UART, and PWM, making it highly versatile for various embedded architectures.

Why Choose This Part

The sensor offers excellent long-term stability through its self-calibration algorithm, reducing maintenance requirements in permanent installations. It provides flexible integration options with both digital (I2C/UART/Modbus) and analog (PWM) outputs. With a typical run current of 20mA and 3 percent accuracy, it balances performance with reasonable power consumption for mains-powered or heavy-duty battery applications.

Applications

Getting Started

Connect the module to a microcontroller using the 2.54mm pitch pins, ensuring a stable 4.5V to 5.5V power supply capable of handling 200mA peak currents. For rapid prototyping, use the I2C interface to query the 12-bit CO2 concentration registers. Implementation should account for the ABC Logic calibration period, which requires the sensor to be exposed to fresh air periodically over a 24-hour cycle.
