I made an automatic watering system with a relay module, soil moisture sensor, arduino, and water pump. I made this because my client wanted a way to keep their plants watered without extra work.

Jul 22, 2024 · We are going to dive into the world of soil moisture sensors. I’ll show you how they work, the different types, and how to assemble them with Arduino. Plus, we’ll build two amazing projects together to exercise what we have been learning so far.

Mar 17, 2024 · So I've been wanting to make a simple water irrigation system with my Arduino R3 development board, a relay, a pump and a soil moisture sensor. The goal is to control the relay with 5V output from GPIO pin 10 and thus controlling the 9v circuit to the pump.

Learn to interface Soil Moisture Sensor with Arduino along with its working, pinout, calibration, reading both analog and digital outputs and hardware overview

It consists of an Arduino UNO microcontroller, a humidity sensor (YL-69), a 1-channel relay module to control a mini water pump, an I2C LCD 16x2 screen for displaying moisture levels and status messages, and a 5V adapter to power the system.

This project utilizes an Arduino Uno development board along with a soil moisture sensor and a relay module to create an automated soil moisture control system. The system turns on the water pump connected to the relay if the soil moisture sensor detects a …

Apr 29, 2025 · A Soil Moisture Sensor measures the water content in the soil by detecting changes in electrical resistance. Dry soil has high resistance, while moist soil has lower resistance, allowing the sensor to provide an analog or …

Practical Applications of Soil Moisture Sensor with Arduino Automated Irrigation System: You can integrate a relay module to control a water pump or solenoid valve based on the soil moisture readings, creating an automated irrigation system.

Dec 1, 2022 · When the Arduino detected the low moisture level in the soil by the sensor, then the Arduino gives the signal to the Relay module to turn on the Pump for automatically watering the plant.

When the value obtained from the soil moiture sensor falls below 300, the water pump starts to run and waters for plants. "300" indicates that the soil is dry. An outlet supplies power to the pump and the relay module (JQC-3FF-S-Z) regulates the pump.
