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 ...

The setup allows periodic readings from a DHT11 temperature and humidity sensor using an Arduino Uno development board and an Ethernet shield. Sensor readings (temperature and humidity) as well as ...

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 ...

Our Smart Home Using Arduino Uno R4 WiFi project is designed for home safety and convenience, integrating temperature, humidity, light, and gas monitoring. Using sensors like DHT11/DHT22, LDR, and ...

Photoelectric sensors detect objects and surface changes using variations in optical properties. Each sensor includes a light emitter and a receiver, with most relying on infrared light. In optical ...

We’ve all been there. Your current project has hit a wall, or the next step will take days to complete, and you need something to do in the meantime. So you start a project that you envision will fit ...

In our daily lives, we use thermometers on various occasions and for various purposes, from medical needs to repair and diagnostic purposes. As you know there are different types of thermometers, and ...

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 ...
