Abstract: All processes in nature and temperature are closely related to our lives and the temperature is more closely related. Temperature detection system has many devices in a very important role, its function is to collect real-time temperature in the system, in order to control after the desired temperature range. Therefore, the temperature measurement method and device research has a very important significance, can be applied to industry and agriculture, environmental monitoring, military and defense fields. The design of the proposed design of a microcontroller-based wireless temperature acquisition circuit, the program is a digital temperature sensor to collect temperature, and then the AT89S51 chip signal processing, the digital display output temperature, and then the data via wireless communication module transmission, a receiving sheet also has a wireless communication module and it is paired. After the data from the microcontroller to control successfully received liquid crystal LCD display real-time temperature.

Keywords: Temperature detection system, microcontroller, temperature sensor
