Working Principle of ACS712 Current Sensor with Arduino The ACS712 sensor operates on the Hall-effect principle. When current flows through the input terminals (IP+ and IP-), it generates a magnetic ...

A data logger built on using the adafruit Datalogging Arduino Shield on an Arduino Mega 2560 R3. 3 types of different units can be measured right now: Current, Voltage, Temperature. The ammount of ...

Poor quality of power supply can often cause power surges, spikes and voltage fluctuations which causing flickering lights, failure of household electrical devices, interference of TV reception, etc.

We present an automation project based on Arduino to monitor and control the cinema hall indoor lighting based on the identification of designed sensor which detects the change in desired voltage. We ...

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 ...

I've just come across a no-name non-contact, high-precision 80 GHz mmWave radar sensor for liquid level detection with a 40m ...

The channel contains a central ion-conduction pore surrounded by voltage sensors, which form what we call ‘voltage-sensor paddles’—hydrophobic, cationic, helix–turn–helix structures on ...
