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 ...

Taking a slightly different direction than the ThirstyLight, the system is based around the popular (and versatile) Arduino board, which is combined with a DIY moisture sensor, and a small piece ...

I'd probably use one module to run 5 or 6 sensors, conformal coated and buried. I'll do some shallow trenching for wires, and mark the sensor locations somehow so I don't mow over them.

Using an Arduino, flow sensor, and colored LEDs, tamberg set up the device to change colors from blue to red when a liter has been used up. For simple tasks, like washing your hands, a Liter is ...

You can’t screw up Arduino’s new DIY electronics kit The $87 Plug and Make Kit includes an Arduino microcomputer, electronic components, and tutorials for building several IoT devices.
