This design resulted from the need for a replacement of the drop sensor in an old vending machine which is no longer in production and therefore hardly obtainable. The replacement is a homemade module ...

This is a very simple touch sensor switch that is build with the 555 timer IC. You just need to touch the metal plate and the relay gets energised and is kept in this state for about 100 seconds, then ...

A sensor signal conditioner (SSC) is an integrated circuit that improves — or conditions — the signal coming from a sensor to reduce noise. The SSC also converts the signal from analog to digital ...
