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. As configured ...

Sensor-head of the module contains two probes ... one simple non-arduino project of a forgetful plant waterer! If you are looking for this option, digital output of the module must be linked to the ...

He suspected EMF interference so as a quick first step he decided to throw together an EMF detector using an Arduino ... treating the recharging circuit from the emergency lights as the most ...

This articles describes how you can use I2C (TWI) communication, Arduino and temperature sensors to measure 3 different temperatures. It can be very helpful when you want to measure the outside, ...

We powered the sensor stick using the 5 volts out available on the Arduino Uno. I2C also requires pull-up resistors on the data (SDA) and clock (SCL) buses. We used two pull up resistors soldered ...
