PURPOSE: A controller for a livestock shed vent is provided to prevent the decrease of the immunity of domestic animals. CONSTITUTION: A controller for a livestock shed vent comprises an automatic operation temperature setting unit(110), a manual operation temperature setting unit(115), an operation signal generating unit(120), a temperature range setting unit(130), a temperature range signal generator(140), a controller(150), and a display unit(160). The automatic operation temperature setting unit automatically sets the operation temperature for operating a vent. The manual operation temperature setting unit is automatically operated by an administrator. The operation signal generating unit generates an operation signal and transmits the signal to the controller. The temperature range setting unit is manually operated by an administrator. The temperature range signal generator generates a temperature range signal and transmits the signal to the controller. The controller is linked with the operation signal and temperature range signal and controls the ventilation amount of the vent. The display unit displays the environmental condition of a livestock shed by numbers or characters.
