Effective water management involves supplying water according to the real requirement, and thus measuring water is very essential step in water management systems. There are many water flow ...

If it's just a sensor, why would it be important? That's a good question, but with proximity sensors being used so heavily in smartphones these days, and that iPhone proximity problem that caused so ...
