The project involves utilizing an Arduino microcontroller and a DHT11 sensor to measure and display real-time temperature and humidity data. The project aims to create a cost-effective and reliable ...

The aim of this project is to develop a circuit that can count the number of people entering and exiting a room using two Infrared (IR) sensors connected to an Arduino UNO. This bidirectional counter ...

I recently had to build an infrared close proximity sensor that could tell if something was dropped in a parcel delivery drop box. After some searching, I ended up using a microcontroller and a piece ...

The past month or so I’ve been playing with the Maxim DS1307 Real-Time-Clock and DS1621 Temperature Sensor ICs. I hooked them up to an Arduino Uno board with a Parallax Serial 16×2 Character LCD. I ...

Have you ever wondered how speed guns measure the speed of moving vehicles or how an athlete's sprint speed is recorded? Normally these speed sensors work with radar or laser technology to bounce back ...

Abstract: COVID-19 and its genetic mutations pose a challenge to the world and affect the economic system of countries. Recently, countries were forced to reduce restrictions on airports, universities ...
