Abstract
We designed a measurement of temperature using the DS18B20. The central processing chip AT89S8252 was used as temperature measurement and control system core. Informationed by RS485 long-distance transmission. LCD displayed the temperature and current time settings. When the temperature below the set temperature value, the controller can start on its own the temperature controller. When the indoor temperature reaches the set temperature, controller can automatically disconnect the power supply electric heater. The temperature controller can set up a lot of time periods and different temperature to save the energy sources.
