Water Softener Circuit using NE555

That circuit is based at a technique to remove or neutralize the salt in water, and protect the pipes at home as well as the washing machines or our selves from salt. Its called water softener and its automated circuit using two 555 timers. The cost of parts is nearly 10$ and its very easy to build it.

Water Sensor Alarm using LM380
This be Water Sensor Alarm Circuit for warn the water level , by when sensor point touch the water. The circuit have a voice loud warn hear immediately. By this circuit uses the integrated circuit LM380 , usual use be power amplifier IC the small-sized , seek buy easy , be usable not difficult. ...
Rain Alarm using NE555
This circuit gives out an alarm when its sensor is wetted by water. A 555 astable multivibrator is used here which gives a tone of about 1kHz upon detecting water. The sensor when wetted by water completes the circuit and makes the 555 oscillate at about 1kHz. The sensor is also shown in th ...

Water Drain Pump Controller by IC 4013
A hole needs to be digged at the lowest place in the celler that have water incomming problems. The hole is about 0.5 x 0.5 x 0.5 meter, at the bottom a large water pump is mounted. Then the different water levels was measured, so we know how to make the sensors. Read more original sourc ...
Water Activated Alarm by IC 555
The circuit uses a 555 timer wired as an astable oscillator and powered by the emitter current of the BC109C. Under dry conditions, the transistor will have no bias current and be fully off. As the probes get wet, a small current flows between base and emitter and the transistor switches on. A l ...
