The present invention provides a growth environment measurement device, for recognizing environment of a growing space in a greenhouse in real-time and constantly maintaining the environment. The growth environment measurement device according to the present invention includes: a housing (10) in which control unit installation part (12) where a control unit (20) is installed and a sensor unit installation part (14) where a sensor unit (30) is installed are partitioned by a separation wall (16) the sensor unit (30) horizontally installed at the sensor unit installation part (14) to provide the control unit (20) with a sensing value, for providing a sensing value for recognizing growth environment a suction fan (37) and a discharge fan (38) respectively installed at an entrance and an exit which are both ends of the sensor unit installation part (14) to suck and discharge air while constantly maintaining a movement amount and the speed of the sucked air and a commercial wireless communication modem (25) for transmitting data recognized in the control unit (20) of the control unit installation part (12) and an own IP address to a main server (40) by a medium of an Internet service provider communication network, wherein the sensor unit installation part (14) includes: a sensor unit (30) installed at a horizontal position lower than the radius height of the suction fan (37) and the discharge fan (38) from a floor, with a CO_2 sensor (32), a temperature-humidity sensor (34), and a temperature sensor (36) which are horizontally spaced apart from each other an air movement space (14b) for providing an air movement passage over the sensor unit (30) and a margin space portion (14a) extending in the widthwise direction at the air movement space (14b) to have a margin space width (W1) larger than the diameter of the suction fan (37) and the discharge fan (38) for reducing the speed of the moving air.COPYRIGHT KIPO 2016본 발명은 제어부(20)가 설치되는 제어부설치부(12)와, 센서부(30)가 설치되는 센서부설치부(14)가
