Abstract

The main purpose or aim for this project is to be able to monitor and water indoor garden automatically with aid of the Internet of Things which connects from hardware to a smartphone with applying Blynk application. This project also has an automatic rainwater harvesting system which will collect rainwater for the purpose of irrigation. This is so that the tank that connected to the planter box will never run out of water unless there is a natural occurrence such as draught where there will be no rain to refill the tank. The project presents the use of correct soil moisture sensors which helps to ease out the pain to monitor and keep records about the changes in soil moisture. Using the Arduino Mega microcontroller with moisture sensor and temperature sensor, temperature is measured and analysed. The soil for a certain duration, provides information related to the moisture status of the soil. The Arduino Mega will collect and process the data received from the sensor. When a threshold moisture level of the soil is reached, the water will supply accordingly. This is essential because water must be provided to the plant at a particular time for a good yield. In addition to that, rainwater harvesting system also connected with rain sensor, ultrasonic sensor and servo motor. Rain sensor will be working together will ultrasonic sensor as the input to the water tank. Once rain is detected and the water level in the tank is low, servo motor will do its work by opening the lid of the tank thus collect rainwater. In conclusion, this project will be very suitable for any residential area and also can be improve for the use of future indoor plantation system.
