ZyTemp ZG09 Air Quality Monitoring CO2 Sensor

Specifications

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.

Features

  • Dual-beam NDIR sensor for enhanced stability and accuracy
  • Gas sampling compatible with both diffusion and flow-through methods
  • Measurement range up to 0-10000 ppm, exceeding indoor air quality requirements
  • Multiple output formats supported: UART, RS485, I2C, PWM, and DAC
  • Fast response time with diffusion type approximately 1 minute (90% rise time)
  • Low power consumption with average current less than 34 mA
  • Wide operating temperature range from 0 to 50°C
  • Compact module size: 32.2mm x 20.2mm x 10.4mm

Applications

  • Indoor air quality monitoring
  • HVAC (heating, ventilation, and air conditioning) systems
  • Greenhouse and agricultural environment control
  • Industrial safety and process control
  • Smart home and building automation
  • Portable air quality detectors
