The Knock Sensor Module detects when the module is tapped, hit or otherwise knocked about.
- Knock Sensor Module
KEY FEATURES OF KNOCK SENSOR MODULE:
- Outputs a logic LOW when module is knocked
- 3.3 and 5V compatible
This module incorporates a mechanical knock sensor consisting of a coiled spring in a clear plastic housing. The output of the module is normally pulled HIGH via an integrated pull-up resistor. When the sensor is knocked or tapped, the output transitions LOW for a short time and then returns back to HIGH.
There is a 3-pin header on the assembly for making connections.
1 x 3 Header
- ‘-‘ = Ground
- Center pin = Vcc (3.3 – 5V)
- S = Signal output, connects to digital input on uC
OUR EVALUATION RESULTS:
This is a basic module that can be used to experiment with a number of industrial type applications which take some type of action when a physical knock or tap on the module is detected.
BEFORE THEY ARE SHIPPED, THESE MODULES ARE:
- Basic operation verified
- Packaged in a resealable ESD bag for protection and easy storage.
