Nowadays, in many indoor leisure places, in order to maintain a comfortable temperature, It usually requires the use of temperature measurement device to adjust the indoor temperature. Both inter-regional and cross-breeding season plant cultivation, temperature and other parameters need to be monitored. Because of A variety of different temperature suitable for the growth of plant, on the need for temperature measurement and control systems, plant growth regulating the temperature required to ensure the effective plant growth environment. By 89S52 microcontroller is programmed to control DS18B20 temperature measurement and temperature conversions. In order to achieve a temperature range of 0 ℃ ~ 40 ℃ adjustable, with alarm, cooling, heating and other functions, non-volatile data. The system uses analog solution, Using light-emitting diodes and buzzer warming and cooling were simulated execution control point device, light-emitting diodes simulated annealing control equipment - air conditioning, heating control equipment with analog buzzer - heaters. With the system, after debugging, go to the actual implementation of the control device.
