▎System introduction         
     The active wireless temperature and humidity monitoring system uses micro-power wireless radio frequency communication technology to replace the traditional method of laying cables to achieve remote online monitoring of temperature. It can realize on-site measurement of temperature and humidity in a variety of places where wiring cannot be laid.
      The active wireless temperature and humidity monitoring system is composed of active wireless sensors (built-in batteries), wireless receivers and host computer monitoring systems. Wireless sensors are installed on the surface of objects or in the measured environment to monitor temperature and humidity in real time. The monitoring data is sent to the corresponding wireless receiver through micro-power wireless transmission technology; the receiver transmits the data to the host computer through 485, Ethernet or GPRS communication methods. Monitoring system to realize remote monitoring and early warning functions of temperature and humidity.
