The Louver Box Multi-Parameter Sensor is an integrated environmental monitoring device designed to measure CO\u2082 concentration, PM2.5\/PM10 particulate matter, light intensity, noise, air temperature, air humidity, and atmospheric pressure.<\/p>\n
The louver box structure effectively protects the sensors from direct solar radiation and reflected ground heat, while also shielding the device from wind, rain, and snow. The ventilated shutter design ensures accurate sensing of surrounding environmental changes and provides stable monitoring performance in outdoor agricultural environments.<\/p>\n
The sensor supports RS485 output with standard MODBUS protocol, allowing convenient integration with environmental monitoring systems, smart agriculture platforms, greenhouse control systems, and data loggers. Optional analog signal outputs are also available for different monitoring requirements.<\/p>\n
Supports up to 9 environmental monitoring parameters in one compact device, including:<\/p>\n
The radiation shield structure prevents direct sunlight and reflected heat interference while ensuring proper airflow for accurate environmental sensing.<\/p>\n
Multiple sensor combinations are available according to project requirements. Optional monitoring parameters can be freely selected for different agricultural applications.<\/p>\n
Supports RS485 communication interface with standard MODBUS protocol for easy integration with monitoring platforms and control systems.<\/p>\n
Each device undergoes factory calibration and testing before delivery to ensure stable performance and reliable monitoring accuracy.<\/p>\n
