Abstract
Abstract: In this paper, an IoT-based smart agriculture monitoring and automatic irrigation system are proposed by using ESP8266 Node MCU. Multiple sensors like capacitive soil moisture sensors are fixed inside to measure moisture content present in the soil which will help in the auto-detection of water requisition in the soil. DS18B20 waterproof temperature sensor will measure the temperature of the soil. The DHT22 is used as a humidity and temperature sensor to measure the air temperature and humidity. Soil relative humidity, air temperature, soil temperature, and relative humidity of air are also measured. A small OLED Display is used which is 0.96 inches in size. If any unwanted intrusion by animals or humans is detected on the farm, a PIR motion sensor is used to detect their motion activity. A rain detector sensor is used to detect rain status. A 5 Volt buzzer is for the Alert system and a 5-volt power relay is to control the water pump, whenever a low quantity of moisture is detected in the soil. Overall by using these farming systems users get more benefits and good results from their farming.
