Flood Detector with Piezoelectric Buzzer

No description available.
This project is designed to sense the presence of water in residential and commercial applications, providing early warning of developing floods using MICROCHIP's PIC12F683-I/P microcontroller. The detector is placed on the floor with probes touching it where water presence, such as a result of leakage or flooding is possible. Upon flood detection, the red led will turn on, and it will trigger the piezoelectric buzzer then it will start making a loud sound. The project will keep itself in alarm mode until the switch is pressed. It is powered by a 9V battery supply. If the battery's voltage is good then the green led flashes every 10 seconds but if the voltage reaches cut-off then red led will flash every 10 seconds, and the piezo will make a short sound to indicate it's time to change the battery.
MICROCHIP Technology's PIC12F683-I/P microcontroller offers all of the advantages of the well recognized mid-range x14 architecture with standardized features including a wide operating voltage of 2.0 V to 5.5 V, on-board EEPROM data memory, and nanowatt technology. Standard analog peripherals include up to 4 channels of 10-bit A/D, an analog comparator module with a single comparator, programmable on-chip voltage reference and a standard Capture/Compare/PWM (CCP) module. It features 256 bytes of EEPROM data memory, extended WDT, MPLAB® ICD-2 programming support or debugging support with optional header adapter, precision internal oscillator – software selectable of 8MHz to 32KHz, and software selectable BOR.
Flood detector with piezoelectric buzzer has the primary objective of reducing water damage. It can provide advance warning of a flood event which can potentially allow the following: the risk to life to be minimized, evacuation of vulnerable assets to safer locations, and installation of flood resilience measures.
