ZCE04B 4-In-One Sensor

The ZCE04B is a compact and high-performance 4-in-1 environmental sensor module that integrates CO₂, temperature, humidity, and TVOC detection in a single device. Designed for accurate and reliable indoor air quality monitoring, it is ideal for integration into smart homes, HVAC systems, environmental monitoring terminals, and building automation solutions.

This sensor uses NDIR technology for CO₂ detection and advanced digital signal processing for stable output across all parameters. With support for RS485 Modbus or UART communication, the ZCE04B offers ease of integration and consistent real-time data for intelligent environmental control.
