1.) I think that spring inside metal tube will be more reliable and less succeptible to permanent deformation. 2.) Arduino has no internal pulldown resistor, so it’s bad idea to use this sensor ...

Last Updated: 7/25/18. Teaching Standards: The SW-420 Vibration Sensor will detect large disturbances and send the data to the Arduino.

The soil moisture sensor module , built around the LM393 comparator, gives an active-low (L) level output when the soil is dry (determined by a pre-setted threshold value). This digital output (wet ...

The wireless vibration sensor system incorporates the FN510 field wireless multifunction module, the LN01 piezoelectric type acceleration sensor, and the FN110 field wireless communication module. Via ...

With four independent 24-bit integrated electronics piezoelectric sensor inputs, the DT9837A is a high-performance USB module for sound and vibration analysis. The sensor inputs are synchronized ...
