Camel bag water indicator [ 140375 ]

By doing many mountain bike by hot weather (where I live), to carry a camel bag (or equivalent) is very common.During a trip, I was always frustrated to never know what is my quantity of water remain in the bag. I spent long to to think about this during these trips. I imagined to put a sensor inside the water bag, or some water debit sensor but nothing satisfy me.

Following up a suggestion contributed to the Siphon-based Rain Meter project, here is a simple capacitive sensor.

Das Projekt  ist eine kapazitive Steuerung auf Basis der Charge-Transfer-Methode im 'Pfeiltastenlayout' . Die Schaltung ist darauf ausgelegt, verschiedene Geräte durch Glasscheiben und Ähnliches hinweg zu steuern. Ein möglicher Anwendungsfall, welcher Anlass für den Entwurf der Schaltung war, ist die Steuerung eines 'Snake-Spiels' in einer Vitrine.

A proximity switch is one which requires your hand to be merely near it as opposed to on it to operate.

The resistive nature of the complementary outputs of a eMDS logic inverter may be used to create a voltage gain stage which allows an output swing of almost the supply voltage. In the circuit shown, eMDS gates are used to extend an amplifier's output swing to almost 5 V. The circuit is particularly useful in 5-V powered analogue systems where improvements in available output swing are needed to maximize the signal processing range and drive margin.
