This sensor device is built to measure the amount of current being used, ... Arduino Based Current Sensor Circuit. Posted Saturday, December 31, ... From its pin configuration, the voltage across ...

The hardware is consists of an Arduino microcontroller (here an Arduino Uno R3) and a pre-wired soil moisture sensor module. The soil moisture sensor module , built around the LM393 comparator, gives ...

At the back of the sensor, we have the op-amp to provide gain to the circuit and reverse voltage protection diode to protect circuit from ESD and reverse voltage protection. A few additional ...

float voltage, degreesC, degreesF; //Declare 3 floating point variables voltage = analogRead(temperaturePin) * 0.004882814; // This equation converts the 0 to 1023 value that analogRead() ...

The Power Supply schematic includes a 5vdc Sensor regulator. This reduces the load (and heat generated) on the Arduino on-board linear regulator, and also allows more effective input protection by ...

What do you need to build an Arduino Speed Sensor. Building an Arduino speed detector using IR technology to measure the speed of a moving object is much more cost-effective, and it is also very ...

There was a time when building electronics and building software were two distinct activities. These days, almost any significant electronic project will use a CPU somewhere, or — at least &#… ...

Abstract: This work develops an automated household utility power monitoring system and data logging in real-time. It utilizes the Arduino Uno Rev3 Microcontroller board intended for use in ...
