Purpose. To detect flooding (leaking) of water.
Scope. In everyday life and at industrial enterprises.
Advantages. The advantage of the device is the ability to reuse (double) individual components (modules).
Description. To solve the specified engineering problem, a weather module for the Arduino controller (rain, moisture and snow sensor) was used as a flood sensor. The board contains an operational amplifier LM393. It processes the signal and can transmit it to the control controller in digital and analog form. To signal operation, there are two LEDs on the board – power and data transmission. In order to regulate the sensitivity threshold, there is a replaceable resistor on the board.
