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 ...

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 ...

First, we’ll build a simple soil moisture monitor with Arduino, according to this schematics. Here’s what you need: Arduino board Breadboard Jumper wires Resistance-based soil moisture sensor Three ...

And when the sensor detects as water/ moisture level is above 500 it means there is a lot of water content so Arduino will turn off the relay leading to turn off the pump. This turning off process is ...

Many factors-including sunlight, water, soil, and pest control-need to be considered when cultivating crops. The farmer has other responsibilities besides keeping an eye on the seedlings. In this way, ...
