Here's a simple cure for your posture and the back pain blues, a posture sensor by Wingman: The simplest distance sensors are ultrasonic or infrared sensors. I went with a SR-HC04 because it is cheap and sufficiently precise. There are no special requirements to the controller so I am using an Attiny85. A...Tags: Attiny85, HC-SR04, ultrasonic

Carl Nobile has developed and released an Arduino library covering the HC-SR04 ultrasonic sensor. He writes: "It features timing, metric conversion, and standard deviation methods, plus a few support methods. It is written in C++ to conserve the namespace. The conversion formula can be easily modified to optimize the accuracy...Tags: HC-SR04, ultrasonic
