Basically the sensor has a reduced size with the following characteristics:
Operating Voltage: +5V
Working Current: <20mA
Sensor Type: Analog or Digital
Water Detection Area:. 1.58in X .63in (40mm X 16mm)
Mounting Hole Size: 0.12in (3mm)
Operating Humidity: 10% to 90% (non-condensing)
Working Temperature: (-30 to 50 degrees C)
If I create a 1 meter long model with the same copper blade that I solder to the copper blade of the sensor, will the system work?
Is there a constraint induced by the electronics or the number of milliamps that would impact the size of the sensor?
because it's my need to detect on a long size....
Why would it change characteristic... That is the question .... 5 V on 4 cm or 100 cm can make the distance easily.
Thanks to precise reason which would the size impact the sensor.
This sensor is based on the resistance of the conductive tracks. According to the second Ohm´s law, R=pL/A. Thus, if you raise the lenght (L), you raise the resistance and change the sensor characteristics.
Probably not.
The resistance of 1 meter of water will be much much lower than 40mm of water.
Once the level reaches 40mm the sensor circuit will probably output a constant value as the water get higher.
have you considered other water level detection technologies, e.g. ultrasonic sensors, TOF laser sensors, etc - have a look at discussion in post read-water-level
