#CMT# #/CMT# The device has a spray gun (24) mounted on a tripod (12), where the device reproduces automatic irrigation identical to manual irrigation. Azimuth and elevation sensors (9, 20) measure azimuth and elevation positions of the gun, respectively. A measurement sensor (43) measures adjustment of fineness of jet. A microcontroller (28) is associated to a non volatile memory e.g. ROM flash memory. Gear motors (4, 11, 50) adjust fineness of the jet from the gun. #CMT#USE : #/CMT# Device for automatic irrigation of a garden with jet. #CMT#ADVANTAGE : #/CMT# The irrigation device is inexpensive, easy to implement, and is convenient for irrigation in case of absence of a user or physical incapability of the user. The device exactly reproduces automatic irrigation identical to manual irrigation, and ensures economy of water by selective irrigation. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a front view of an automatic irrigation device. 4, 11, 50 : Gear motors 9 : Azimuth sensor 12 : Tripod 20 : Elevation sensor 24 : Spray gun 28 : Microcontroller 43 : Measurement sensor. |
