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 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 ...

These smart sensors can be used for various purposes, like determining the ambient temperature, checking the moisture in the soil ... DIYables LDR For Raspberry Pi And Arduino Light-Dependent ...

This isn’t about connecting a temperature sensor in your Arduino. This build is about using the temperature sensor in your clock. The ATMega328p, the chip at the heart of all your Arduino Uno ...
