Arduino Based Automatic Plant Watering System Using Soil Moisture Sensor For Botanical Purpose
During summers, most people are too lazy to water the potted plants on their rooftop gardens every day. Explained in this section is a simple and exciting automatic plant watering system that you can build yourself in just a few hours. It is an Arduino based automatic plant watering system that uses a soil moisture sensor. The circuit diagram of the automatic plant watering system is shown in Fig. You can power the Arduino board using a 7V to 12V wall wart or plug-in adaptor or solar panel. You need a separate 12V battery or power supply or solar panel for the pump motor. Two types of soil moisture sensors are available in the market—contact and non-contact sensors.
Table of Contents. No matter whichever weather it is, either too hot and cold or too dry and wet it is very crucial to control the amount of water reaches to the plants. So, It will be effective to use an idea of automatic plant watering system which waters plants when they need it. To reduce manual activities for the human to watering plant, an idea of plant watering system is adopted. System reports its current states and sends the reminder message about watering plants and to add water to the tank.
Add the following snippet to your HTML:. This system monitors the moisture of soil and waters it by 5v DC motor based water pump when needed. Whenever me and my family go for vacations, I used to get worried about my plants because they need water on regular basis. I gone through several options to solve this problem as plants need water according to the moisture level of soil. In this system, soil moisture sensor senses the moisture level of the soil. If soil will get dry then sensor senses low moisture level and automatically switches on the water pump to supply water to the plant.
This project is about a moisture-sensing automatic plant watering system using microcontroller. The system simply senses the moisture level and switches on the irrigation pump when the moisture is below the set limit. The system switches off the pump when the moisture rises above the set point. The moisture level threshold can be set using a trim pot on the system. The system can be divided into three section as follows. YL 69 moisture sensing probe is used to sense the moisture here.
