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, ...

Sensor system which utilizes light dependent resistors, PIR motion sensors, microcontrollers, and a Bluetooth module to automate the lighting in a room to save energy. - ...

The pulse sensor comes with a flat ribbon cable with three male header connectors. The Pinout of the Pulse sensor is given below: S(Signal) is the Analog output pin of the Sensor Module that will give ...

Let me introduce another simple microcontroller-based do-it-yourself circuit that detects motion and excites a light source in a flash. The “snooper” here is an ordinary passive infrared (PIR) motion ...

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 ...

Time synchronization for wireless sensors is important for a proper interpretation of measurements, particularly for acceleration measurements to estimate mode-shapes. This paper presents a new time ...

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: LPG is an alternative fuel used for daily use. Due to its low cost and ease of installation. This article covers an Arduino-based gas detection system that uses an Arduino UNO R3 board and ...
