This DIY gas leakage detector is designed for educational and basic monitoring purposes. For critical safety applications, ...

When the sensor-head is inserted in wet soil, mositure bridges the probes through a low-resistance path (when soil is dry, resistance between the probes is also high). A potentiometer is included in ...

It uses Arduino Duemilanove microcontroller board. Two wires placed in the soil pot form a variable resistor, whose resistance varies depending on soil moisture. This variable resistor is connected in ...

The sensor shown here is essentially two plates mounted side-by-side, attached to an Arduino Nano using the Capacitor library which uses just two pins, one digital and one analog.

The Arduino Nano itself is the most basic and oldest of the group, and just like its many iterations, it's designed to work primarily with breadboards, making it a great tool for prototyping.

Coffee has always been an important part of the internet; the first webcam ever was in the Trojan Room of the Cambridge University Computer Laboratory to monitor the contents of a coffee pot. Now, … ...
