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 ...

Voltage Measurement measure analog voltage input from pin A0 and calculate the corresponding voltage value using an Arduino board.

From the looks of it, his hardware configuration is relatively simple. All it uses is a TSL261 Light-to-Voltage sensor connected to an Arduino with an Ethernet shield attached.

Arduino Mega board expands tracking time of an oscilloscope to a maximum of 12 hours, for example to display the (dis)charging curve of a battery. Suppose you want to measure a slowly-varying voltage ...

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 ...
