The soil moisture sensor module , built around the LM393 comparator, gives an active-low (L) level output when the soil is dry (determined by a pre-setted threshold value). This digital output (wet ...

This project details the construction of a soil moisture sensor using an Arduino Uno microcontroller. The sensor leverages the electrical conductivity of soil to determine its moisture content. Dry ...

Arduino Uno: This is the micro-controller and main processing unit of the system. It main controls input from the DHT11 sensor and Soil Moisture Sensor Module and displays on Serial Monitor. Soil ...

Basically we have the Arduino Uno R4 which will read the soil moisture level using the soil moisture sensor. If the moisture is low it will automatically turn on the water pump via the relay module.

In this review of the Maker Uno RP2040 board with the Arduino IDE we could blink LEDs, control RGB LED lights, press the user button to turn on one LED or make the buzzer output some melody, control a ...

In this paper, Arduino based Smart Irrigation System using GSM Module and Sun Tracking Solar system has been explored. This system is hoped to be very convenient and affordable for the people of rural ...

So, we can consider as if the sensor reading goes below 300 means there is no water content in soil and more than 500 is more than enough water content present in soil. Whenever the sensor detects ...

This project is an Automatic Smart Irrigation System using an Arduino Uno, soil moisture sensor, LM35 temperature sensor, DHT11, and Bluetooth module (HC-05). The system controls two irrigation ...
