The hardware is consists of an Arduino microcontroller (here an Arduino Uno R3) and a pre-wired soil moisture sensor module. The soil moisture sensor module , built around the LM393 comparator, gives ...

Use 5V for soil moisture sensors with Arduino UNO. While the sensor can work with 3.3V, using 5V provides better analog resolution and more reliable readings. The analog output voltage will scale with ...

Our kit includes the Maker Uno RP2040 itself, four Grove to jumper cables, a USB-A to USB-C cable, a soil moisture sensor with one Grove cable, an HC-SR04 ultrasonic sensor with a Grove cable, a SG90 ...

An Arduino Uno moisture sensor measures soil moisture levels by detecting electrical resistance. It's used in gardening and agriculture to monitor soil hydration, triggering irrigation systems when ...

This is a simple arduino project for a soil moisture sensor that will light up a LED at a certain moisture level. It uses Arduino Duemilanove microcontroller board. Two wires placed in the soil pot ...

The Arduino UNO is the brain of this whole project. It controls the motor pump according to the moisture in the soil which is given by the moisture sensor. To power the circuit, I am using an external ...

Automatic Smart Plant Watering System is a smarter solution that works on Arduino Uno, which can automatically operate for plant watering at optimal moisture conditions of soil. It checks the moisture ...

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 ...
