water level sensor

water level sensor

DESCRIPTION

Water sensor brick is designed for water detection, which can be widely used in sensing the rainfall, water level, even the liquate leakage.

The module is mainly comprised of 3 parts:

1. An Electronic brick connector,
2. a 1 MΩ resistor, and
3. several lines of bare conducting wires.

This sensor works by having a series of exposed traces connected to ground and interlaced between the grounded traces are the sense traces.

The sensor traces have a weak pull-up resistor of 1 MΩ.

resistor will pull the sensor trace value high until a drop of water shorts the sensor trace to the grounded trace.

Believe it or not, this circuit will work with the digital I/O pins of your Arduino or you can use it with the analog pins to detect the amount of water induced contact between the grounded and sensor traces.

This item can judge the water level through with a series of exposed parallel wires stitch to measure the water droplet/water size .

This item can easily change the water size to an analog signal, and output analog value can directly be used in the program function to trigger water level alarm.
