The structures of a system based on the MCS-51 single-chip were introduced, the hardware composition andthe sofrware design were described. The measuring system consists of three parts: sensors, slave chip-processor, andinterface program. And the system with the function as multi-sensor, communication with PC, data protection duringpower loss and automatic smartwatch was presented. With the help of keyboard, consumer can set the required value oftemperature and humidity, and also the upper-lower limit of temperature and humidity that will be given an alarm whenthe temperature and humidity over the limit. The temperature and humidity measuring system not only has low cost, butalso has high reliability, and it has good prospect for application.
