PIC-Based Water-Tank Level Meter; Pt.1
01 November 2007
Looking for a water tank level meter that's easy to install? One that's accurate but doesn't need a complicated in-tank sensor? This PIC-based unit uses a pressure sensor to monitor water level and it displays tank level at the press of a switch. It can also send its readings to a base station with an LCD readout via an RF link.

He wanted to know if the claims were true: could this little device really save money by reducing the amount of power used by your electrical appliances? Have Newton, Ohm, Kirchoff, Thevenin et al been wrong all along?
