[lingib]’s dual sensor echo locator uses two HY-SRF05s, but the cheap and plentiful HC-SR04s will work, too. Both sensors are arranged for maximum beam overlap and wired up to an Arduino Uno.

Built your very own parking sensors for the car using nothing more than an Arduino board and cheap components you can find online ...

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 ...

With over 20 unique sensor types, and the ability to be used with several different development platforms, Tarts wireless sensors allow for endless sensing, monitoring and control possibilities.

Aiming at sensor fusion application development, Rutronik has created a single Arduino-compatible board with a plethora of sensors from Infineon, Bosch SE and Sensirion. Called ‘RAB1 – Sensorfusion’, ...

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 ...
