The invention discloses a field measuring and controlling unit for fowl intensive cultivation. The field measuring and controlling unit for the fowl intensive cultivation consists of four function parts of a controller, an input device, an output device, and a wireless network. The controller uses a single chip STC12C5A60S2 as the core. The single chip collects the input information of an illumination sensor, an ammonia gas sensor, a temperature sensor and a humidity sensor in the cultivation field, the opening/closing of an air window, a fan and a wet curtain is adjusted by the analysis operation processing, so that the ammonia concentration, the illumination intensity, and the temperature/humidity of the cultivation field are within the optimal range; while the cultivation field occurs the abnormal situation (such as excess temperature, excess ammonia concentration), a buzzer sends an alarm signal; a function key module is used for adjusting and setting the main control parameters of the measuring and controlling unit in situ; the voice communication between the field and a duty room can be realized by a microphone; and a camera and a wireless network transmission technology are used for performing the all-dimensional and multi-factor monitoring to a fowl house, so the operation states of executing devices, such as the air window, the fan and the wet curtain, in the fowl cultivation field can be known in real time.
