This the Telaire T6713 / T67XX a Carbon Dioxide CO2 sensor for indoor air quality, energy saving application, control of ventilation, environmental purpose, farming, and clinical instrumentation. The T67XX is already factory calibrated sensor than can measure the concentration level of CO2 up to 0 to 500 ppm range at accuracy of 400 to 5000  ppm +/- 30 ppm ± 3 % of data acquisition  and runs at 4.5v ~ 5.5vdc and support i2c communication, UART protocol. This device has integrated a Non Dispersive Infrared (NDIR), gold plated optics diffusion sampling with self-calibrated algorithm. For testing we will going to use a Arduino Nano Microcontroller. However the T67XX also tested in ESP32/ESP8266, STM32, AVR, and Modbus. For more readings please refer to the product datasheet below.
