The mass layout of the cable in field brings many problems in the automatic irrigation control system such as installation, maintenance, and extension. This article suggests a wireless broadcast irrigation control system and designs a low power wireless DC solenoid valve based on OOK modulation and powered by battery. It also introduces how to design and implement the transmission control module with discrete input and digital input. Finally, it provides an application example of automatic irrigation control system based on wireless solenoid valve throughout the greenhouse irrigation in a plantation.
