S400W Wireless Zigbee Real-Time Monitor System Solution


S400W wireless temperature and humidity recorder is high speed, intelligent temperature and humidity recorder designed by the China map. The instrument adopts wireless data transmission to collect and record the temperature and humidity data. It is equipped with a record memory that stores 8192 sets of data and enables real-time remote monitoring of the warehouse, laboratory, refrigerator, cold storage environment, the data transmission of 2.4G wireless network, no wiring, simple operation, reliable performance.

Compared with the traditional temperature and humidity recorder, the wireless temperature and humidity recorder can meet the fast working speed. The most important thing is that in 24 hours unattended environment can achieve remote real-time monitoring. Just put a receiver in the office, through the 2.4G wireless network and monitoring software, you can easily sit in the office to see clearly check the changes of temperature and humidity in each environment, real-time monitoring at the same time, also can query history, temperature and humidity exceed the standard, The server will send an alarm and receive an alarm message for the staff to handle in time. Wireless temperature and humidity recorder is very suitable for fixed point temperature and humidity monitoring and recording.
