Automatic Irrigation System Using Soil Moisture Sensor And Arduino

The value of this sensor varies from 0 1023.

Automatic irrigation system using soil moisture sensor and arduino.

If soil will get dry then sensor senses low moisture level and automatically switches on the water pump to supply water to the plant. 0 being most wet condition and 1023 being very dry condition. It will not only automatically irrigate the water based on the moisture level in the soil but also send the data to thingspeak server to keep track of the land condition. We are using an arduino microcontroller to control and sense the thing in the projects such as sense or measure the moisture in the soil we are using soil moisture sensor.

The proposed system is developed to automatically water the plants when the soil moisture sensor has detected the soil is insufficient of water by using the arduino as the center core. In an automatic plant watering system or we can say it smart irrigation system. Hands on project on how to make the smart irrigation prototype using arduino. Here we are building a iot based irrigation system using esp8266 nodemcu module and dht11 sensor.

The output of the sensor will be from 0 1023. The soil moisture sensor is a sensor which varies the value when it contacts the moisture. In this system soil moisture sensor senses the moisture level of the soil. The soil moisture sensor values depends on the resistance of the soil.

The soil moisture sensor is inserted in the soil. The soil moisture sensor measures the conductivity of the. Basically it is a resistor that works on moisture. The lm35 is a precision integrated circuit temperature sensors whose output voltage is linearly.

How does the arduino automatic irrigation sensor work. Automatic watering system using fc 28 moisture sensor with arduino by admin published november 20 2017 updated april 17 2020 automatic irrigation is a concept of controlled watering of plants without any manual operations so as to maintain a water level ideal for its cultivation. Automattic irrigation and plant watering system using arduino and soil moisture sensor this project is about a moisture sensing automatic plant watering system using arduino uno. The working of the circuit is as follows.

The idea of the project is to implement an automatic irrigation system by sensing the moisture of the soil. The moisture is measured in percentage. The soil moisture sensor will sense the moisture present in the soil and will give the output to the arduino. Hands on project on how to make the smart irrigation prototype using arduino water pump and soil moisture sensor.

The system reads the moisture content of the soil using soil moisture sensor and switches on the motor when the moisture is below the set limit. The lm393 driver is a dual differential comparator which compares the sensor voltage with fixed 5v supply voltage. As plant get sufficient water and soil get wet then sensor senses. Therefore we will map these values as 0 100.
