PCB muon detector
Schematics designed by Robert Hart:
Thanks to Robert Hart for his fantastic ideas, please check his site for further experiments:
This project uses 3 Geiger tubes to create a muon detector, it also uses a step up boost DC-DC to convert from 5V to 400V for Geiger tubes.
This main PCB has...
Water detector with 4 level stages. Each stage makes the 555 timer to give a supply period for the buzzer. The active buzzer transmits sound with a pause period between 0.5-3 seconds, depending on the level detected.
I am only a beginner at this. So would be very happy for anyone to point out problem with the
design. This would be very helpful.
The unit is design to be connected to 7 float similar to the one in the image,(attach file)
on the block Bottom right.
As the water rises the LED bar on the left indicates the level. Power & Buzzer indicator.
With the rotary switch top right to can set t...
