Next we connected the water flow sensor’s output to the Arduino board (filled with the sketch) and allowed water flow through the water flow sensor at a steady rate of about 1 Litre/minute. Besides ...

This digital output can be input to a microprocessor where illuminance (ambient light level) in lux is derived using an empirical formula to approximate the human eye response. Commonly available ...

Adding a photoresistor (light sensor) and a thermistor (temperature sensor) and connecting them to a programmed Arduino gave me a gadget that monitors the environment of a single plant. You can ...

Nexus 6 has an RGB LED sensor, and you can enable it via Light Flow. Thanks to one intuitive XDA user, the Google Nexus 6 has been found to have an LED built into the center of the top speaker grill.
