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 ...

As such, I'd like to build myself some wireless moisture sensors for moderate scale production (consider 50 test points reasonable).

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 ...

Hi, I'm Bill. I'm a software developer with a passion for making and electronics. I do a lot of things and here is where I document my learning in order to be able to inspire other people to make ...

The ESP02 based system has been quite reliable. Now I need to finish hooking up moisture sensors. I'm moving to a JSON protocol - a friend is doing a web interface for the system. So I've been ...
