A Low-Cost Smart Irrigation System using IoT

EasyChair Preprint no. 2872

Abstract

Today we are living in the 21st century where automation is playing an important role in human life. Automation allows us to control appliances automatic control. It not only provides comfort but also reduces energy consumption, increase efficiency and saves time. Today industries use automation and control mechanism which is high in cost and not suitable for use in agricultural farms. Hence, this project focuses on the development of a smart irrigation technology at a low cost which is usable for Indian farmers.

The farm parameters such as soil moisture, temperature, humidity which are essential to be maintained are considered in this work. These parameters are monitored and the measurement values are sent through the main gateway from sub-nodes using special communication protocols. The data collected in the microcontroller is then sent to the cloud platform from where the farmer is able to monitor his farm. Under extreme conditions, the farmer is alerted by notifications. This makes the farmer take necessary actions. The farmer will be able to control the motor and valves in the field based on the requirement. This setup can be made crop-specific and will improve the yield resulting in the economic growth of the country.

The moisture is measured by resistive hygrometer which is connected with a soil moisture module which converts the resistance value to voltage. This voltage is read by an ADC which gives digital value of soil moisture. The temperature and humidity are measured using the DHT11 module which contains a thermistor for temperature measurement and capacitive humidity sensor.

Keyphrases: Arduino, Cloud, Humidity, Node MCU, soil moisture, Temperature
