Efficient water management for greenland using soil moisture sensor

Abstract

The paper 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 starting form cultivation to harvesting period of crops. Using the Arduino-Uno microcontroller with hygrometer moisture sensor and temperature sensor, humidity and temperature are measured and analysed. The hygrometer is sensor which, when placed in a soil for a certain duration, provides information related to the moisture status of the soil. The Arduino-Uno will collect and process the data received from the hygrometer. When a threshold moisture level of the soil is reached, the water will supplied accordingly. This is essential because water must be provided to the plant at a particular time for a good yield. Timestamps and humidity levels will be recorded in a CSV (Comma Separated Values) file throughout the process using raspberry pi. Raspberry pi will then store this CSV file over the internet. User can access this file from any remote location to keep a track of his crops or plants. This system efficiently manages both, water and energy, as well as ensures the healthy growth of the plant without the presence of the user.
