This project uses an arduino to communicate with the Wavshare dust sensor: this sensor uses a Sharp light emitter techology to be able to measure dust density. We use an Arduino for reading the data ...

To use the Keyboard you simply place your finger over the light sensor. A light will flash three times. Now on each following flash you will cover the light sensor or leave it. There is a list of ...

Now we can stepped into the light with our favorite microcontroller Arduino! Since a vast number of analog/digital ambient light sensors/light sensor modules are now available at reasonable price, ...

If you are designing your own intelligent “Graden Computer” with an optional digital plant moisture sensor/water pump controller that lights an LED to alert the user when it is time to water a potted ...

The DHT22 temperature and humidity sensor is a versatile and cost-effective sensor used to measure ambient temperature and humidity for a wide range of applications. It is based on a digital signal ...

In this tutorial, we will learn to Guide you about how you can interface a heartbeat sensor with an Arduino to measure live-heartbeat of any person. We will be also interfacing an OLED display to the ...

Automating household or office systems can be achieved using an Arduino Nano, a passive infrared (PIR) motion sensor, and a relay. The primary aim is to create a control system that activates or ...

Abstract: This paper presents an Arduino-based monitoring system that measures four physicochemical parameters of water: pH, temperature, turbidity, and electrical conductivity to identify possible ...

The ADIY pH sensor module can precisely measure the potential of hydrogen (pH) of any liquid. Rajguru Electronics has released the ADIY pH sensor module, a sensor for measuring the potential of ...
