The pressure well draw off water remind circuit is as shown. This circuit is composed of the water level probe A, music IC CIC3830, and the speaker.etc. If the water level is higher than probe A, BG2 turns on, the CIC3830 starts working, the output music signal is amplified by BG1 and then promote the sound speaker Y to remind the master to draw off water. If the water level is lower than probe A, BG2 turns off, the CIC3830 stops working to send out music signal. If you don't draw off the water, the circuit will continue to play the music until you draw off the water, so we can avoid the well pipe damaged in the cold winter.
