Product Introduction

The ZG09 CO2 Module is a high-performance carbon dioxide sensor module designed for accurate and reliable CO2 concentration measurement. It utilizes dual-beam NDIR (Non-Dispersive Infrared) sensing technology to provide precise readings across a wide measurement range. The module supports multiple communication interfaces, making it versatile for various applications including indoor air quality monitoring, HVAC systems, and industrial control. With its compact design and low power consumption, the ZG09 is suitable for both portable and fixed installations.
