After some searching, I ended up using a microcontroller and a piece of code borrowed from the web that I tweaked and adapted. The microcontroller-based concept was chosen because I wanted to scale ...

This tiny proximity sensor looks like a nifty chip, providing distance measurements up to 200 mm and an ambient light sensor in one package. The routing table has an LCD display and buttons ...

10:27 am March 6, 2019 By Julian Horsey Makers, Arduino enthusiasts and students looking to learn more about ultrasonic sensors, may be interested in this DIY Arduino radar created by Mr Innovative.

The usual solution is to use some sort of statistical averaging to reduce noise in sensor readings. This is often called “filtering”. The goal of this quick project is to experiment with two types of ...

[Ashish Choudhary] married an Arduino with a display and a pollution sensor to give readings of the PM2.5 and PM10 levels in the air.

This is an Arduino-based Proximity Sensor circuit wired using the popular HC-SR04 Ultrasonic ranging module,used here for non-contact object detection purpose. The HC-SR04 module includes ultrasonic ...
