A Simple and Convenient Technique for the Remote Temperature Measurement and Alert over LAN

To keep LAN running safely and reliably, it is often required to measure the temperature of the central computer room in case of overheat conditions. Overheat which is mostly due to the failure of air-condition could cause damage to Servers, Switchs, Firewall, Storage Units, and etc. In summer, alerting techniques for overheat become more and more important. Here, based on a USB temperate sensor which costs less than 100 yuan RMB, and lines of CMD codes, the temperatures were measured for the central computer room and the overheat alerts were sent over the LAN.
