SEN0204 NPN Version
cwills 2024-06-11 08:04:26 163 Views2 Replies Is there an NPN version of this sensor? I need to have an active output when the water level drops below the sensor rather than above, similar to the SEN0368 in the negative direction. Since this is intended for an existing design I cannot use an inverter on the output. The SEN0368 seems to be rather ESD sensitive and is not reliable for this reason.

If needed, you can make a water level indicator by yourself like this: https://www.theengineeringprojects.com/2022/02/water-level-indicator-using-arduino.html

The SEN0204 water level sensor by DFRobot is typically designed with PNP output. Unfortunately, there doesn't seem to be a direct NPN version of the SEN0204 available from DFRobot.
