A moisture and temperature control system was developed for the terminal box in transformer substations,which was composed of a wireless temperature and humidity controller, an infrared handheld device and a monitoringplatform. The controller could exchange information with the monitoring platform by the ZigBee wireless network, andthe handheld device could read and set the parameters in the controller via infrared rays, This paper presented a newanti- condensation control scheme and developed a semiconductor refrigeration dehumidifier. Applying fuzzy PIDtechnology and semiconductor refrigeration dehumidification techniques, the device embodied a good moistureproofeffect . The handheld device made it very convenient for maintenance personnel to do routing inspection on site. Cen-tralized monitoring of the terminal boxes in the transformer substation could be achieved through the platform. This pa-per discussed the hardware and software design of the System, mainly focusing on the design scheme of the wirelesstemperature and humidity controller. The system has been proved to be very practical in that it has been put into usein some substations by far.
