Abstract
The present invention relates to a system and components thereof for intelligently watering an environment. The system comprises at least one sensor for monitoring particular environmental conditions, and at least one electrically powered valve that receives wireless information signals from the sensor and controls a watering device based on the signals. Power control units repeatedly toggle the sensor and valve between powered and unpowered states to conserve energy. The power control units are configured so that the powered states of the sensor and valve overlap in time to make it possible for the valve to receive the wireless information signals from the sensor.
