Zhengzhou Bee IoT Technology Co., Ltd

The YF200 air quality monitoring system integrates over ten types of high-precision sensors, covering core monitoring units such as oxygen, PM2.5, PM10, CO, CO2, hydrogen sulfide, methane, combustible gases, and temperature and humidity. It also supports flexible expansion of environmental parameter sensors such as wind speed, wind direction, and noise, creating a comprehensive, three-dimensional monitoring network. The system precisely adapts to multi-dimensional application scenarios and meets the precise monitoring needs of complex environments such as smart campuses, urban parks, residential communities, industrial production, and modern agriculture. By utilizing a dual-mode transmission system featuring RS485 wired transmission and LoRaWan low-power wireless communication, data is seamlessly connected to the IoT cloud platform, providing one-stop technical support for environmental quality assessment and gas detection IoT solutions, contributing to the development of a smart environmental ecosystem.
