     Abstract：Based on AT89C51 singlechip to produce a temperature controller which is used to turn heating or cooling equipment automatically so that the temperature of hen house reaches the set temperature When the indoor temperature is below the set temperature limit the controller will connect electric refrigeration equipment and it will set off until the temperature is equal to the mean minimum temperature when the temperature of hen house is higher than the set temperature limit the controller switches electric refrigeration equipment automatically until it is equal to the set temperature
     Key words temperature measurement and controlmicrocontroller chicken house．
