This Arduino project implements a smart bin that uses an ultrasonic sensor to detect objects and control an LED indicator. When an object is detected within 14cm of the sensor, the LED turns on for 5 ...

This sensor is built for detecting ppm of certain gas molecules, such as VOC, ethanol, ammonia, Hydrogen sulphide, etc. This sensor can't distinguish different gas molecules. Please use the table ...

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 ...

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 ...

Tilt sensors are essential components in security alarm systems today. Standalone tilt sensors sense tilt angle or movement. Tilt sensors can be implemented using mercury and roller ball technology, ...

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 ...

What is an Air Quality Monitoring System? An air quality monitoring system is a device that measures pollutants in the environment and is able to provide real-time information on the state of air ...

Designed by Nova Radio Labs in the US, the Novaduino Environmental Sensor Kit is an Arduino-programmable air quality and weather monitoring solution built around the company’s own Novaduino Display ...
