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 ...

Makers, hobbyists and electronic enthusiasts looking for a project to keep them busy this weekend may be interested in this awesome Arduino temperature and humidity sensor which has been created ...

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 ...

it’s defined right there in Arduino.h. Great stuff! The I2C (“Wire”) library has also gotten the ESP32 treatment, and worked just as it should with an LM75 temperature sensor. This is my ...

Perhaps you don't have indoor plants to take care of, or you're not interested in knowing what the current temperature and humidity ... with only an Arduino UNO, ultrasonic sensor, force-sensitive ...
