Water level detector with PIC12F683
Firmware v1.0
Hi-tech PICC source code
This is a PIC based water level detector.Why I choose PIC ? First I have a lot of them for my DIY projects,second I want to use this project with 4.5V batteries and PIC Micro has the sleep mode which has very low power consumption,so the life of the battery can be extended.Most of time of this circuit operates in the sleep mode and wake-up from sleep through watchdog time-out every about 2 second.When the CPU Wake-up it will check the sensor probes if the sensor probes submersed in the water it wiil sound Beep,Beep and then go to sleep mode.The sensor probes that I use are solid copper wires.
