ZEHS04 (MTI.AQMS.WS.ZEHSO4) is a diffusion type multi-in-one module, mounted with atmospheric monitoring module ZE12A, to detect CO, SO2, NO2, and O3. It is also compatible to connect with dust sensor module, temperature and humidity sensor module externally. With TTL or RS485 output, it is convenient to use and debug, which greatly shortens the user’s design and development cycle, and meets customers’ needs for different gas detection occasions.
