This work aims at developing an entirely automated plant/crop watering system. The main motivation behind this system is to conserve the wastage of water and to effectively manage the amount of watering of the plants. It also aims at reducing human labor, effort, and errors due to human negligence. It uses solar panels to provide power to the system at daytime. Solar energy is used to run the system during daytime and charge the batteries to operate at night. It uses moisture sensors to sense the level of moisture in the soil. When the moisture content of the soil goes below a certain limit for a plant/crop, the pump system is triggered and the plant/crop is watered. The plants are watered efficiently till the desired value is reached and the pump is switched off automatically.
