Unfortunately this example did not make me happy so I decided to convert it into a simple Arduino Library that is very easy to use from an Arduino Software IDE. It also supports Audio/Video Remote ...

A pocket-size ultrasonic bladder-volume sensor has been constructed and tested with successful results. This paper describes the sensor and presents results from its use on healthy volunteers.

The complexity here is that we need to fix the circuit in a mobile and remote place—the helmet. So, simplifying the circuit is most important to make it compact and reliable. The circuit diagram ...

This library supports only one DS18B20 per Arduino/ MCU pin ... If a value occurs only once in a while, wiring is often the cause, or it can be caused by e.g. induction e.g. switching on a motor while ...
