Automatic Irrigation System Using Soil Moisture Sensor And Arduino

The soil moisture sensor is inserted in the soil.

Automatic irrigation system using soil moisture sensor and arduino.

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. Depending on the quality of the sensor it must be inserted near the roots of the plant. 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. The lm35 is a precision integrated circuit temperature sensors whose output voltage is linearly.

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 soil moisture sensor is a sensor which varies the value when it contacts the moisture. The soil moisture sensor will sense the moisture present in the soil and will give the output to the arduino. Basically it is a resistor that works on moisture.

Hands on project on how to make the smart irrigation prototype using arduino. The working of the circuit is as follows. Hands on project on how to make the smart irrigation prototype using arduino water pump and soil moisture sensor. The moisture is measured in percentage.

The lm393 driver is a dual differential comparator which compares the sensor voltage with fixed 5v supply voltage. In an automatic plant watering system or we can say it smart irrigation system. If soil will get dry then sensor senses low moisture level and automatically switches on the water pump to supply water to the plant. 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. So i have made automatic plant watering system using arduino uno. In this system soil moisture sensor senses the moisture level of the soil. The idea of the project is to implement an automatic irrigation system by sensing the moisture of the soil.

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. 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. How does the arduino automatic irrigation sensor work. The value of this sensor varies from 0 1023.

As plant get sufficient water and soil get wet then sensor senses. The smart irrigation system has wide scope to automate the complete irrigation system. Therefore we will map these values as 0 100. 0 being most wet condition and 1023 being very dry condition.
