ELT sensor is a company located in Korea and leads gas sensor technology with 20 years of experience and top technology in the NDIR gas sensor field.


This module is a "carbon dioxide" gas measurement module with non-dispersive infrared (NDIR) method.


It guarantees high accuracy and long-term stability through the development and production of its own sensors.


It provides high quality by shipping after individual correction and correction work before product release.


Carbon dioxide measurement sensors are environmental sensors such as indoor air quality monitors, air purifiers, building management, automobiles, livestock, industries, public places, agricultural use, CA storage, HVAC, and medical care.


Carbon dioxide concentration monitoring can manage and supervise carbon dioxide levels to prevent carbon dioxide poisoning and maintain comfortable indoor air quality. It can also be applied to vehicles, schools, and library offices to prevent drowsiness.


It supports UART, I2C, PWM, and Analog outputs for easy application and use.
