Tips: Wireless temperature and humidity remote monitoring system
Wireless temperature and humidity remote monitoring system has a simple hardware structure. A wireless temperature and humidity sensor adopts battery for power supply and it can be placed in any position by needs without wiring. The temperature and humidity data are transmitted to the monitoring center through wireless communication. Wireless temperature and humidity monitoring system can monitor a large area of multi points temperature and humidity, collects the temperature and humidity data in real time, manages data and records the data. The monitoring operator can monitor the temperature and humidity conditions and changes in real time anywhere in LAN or WAN, so as to ensure the safe operation of important equipment. Automatic monitoring software can also be used to set alarm settings on web or client, to realize the mail alarm, message alarm, telephone alarm, real person voice alarm, etc.

Wide range of applications

I recently bought this remote temperature and humidity sensor. After using it for a while, I feel it is very good overall. I use it for computer room environment monitoring. The temperature and humidity data can be transmitted to the central control system in real time, which is very suitable for scenarios that require remote monitoring.
