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 ...

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 automatic plant watering system uses an Arduino and soil moisture sensor to maintain optimal soil moisture. When the soil is dry, the sensor activates a relay to turn on a water pump. Once the ...

Sistema de monitoramento do solo via microcontroladores Esp32, LoRa, NPK Soil Sensor 7x1 e Arduino Uno R3 Sistema capaz de monitorar o solo, com medidas como temperatura, umidade, condutividade ...

The system is based on an Arduino MKR WAN 1310, and monitoring points include ambient light sensors, moisture sensors and the aforementioned soil sensors. Data from these is transmitted via the MODBUS ...

We connected $\\mathbf{p H}$ sensor and solar cell into Arduino Board to control data transmission via red laser communication or popular known as visible light communication (VLC). The sensor was ...
