Internet of thing for smart garden: Automatic plant sprinkler

Soil moisture is one of the crucial factors that affect plant growth. Whether the soil is moist or not depends on the amount of water it contains. Dry soil will interfere with the process of photosynthesis. It affects plant growth, resulting in low-quality yields. Internet of things (IoT) based cerated smart garden system on solving this problem. This study aims to build an internet-based automatic plant watering system by controlling soil moisture in plants and monitoring the water level in the reservoir using the ESP8266 module, soil moisture sensor, ultrasonic sensor, relay, LCD, and water pump. The tests that have been carried out show that the system can automatically water plants which can control in real-time with an average response time of 0.5 s.
