Shock and Impulse

Description

A sensor designed to act as a switch. Detects tapping/knocking or vibration.

Also called: tap sensor, knock sensor, shake sensor, impact sensor, spring switch, vibration sensor, percussive sensor, KY002, KY031.

Found in kits: 37 sensors, 45 sensors (vertical element, shock).

Found in kits: 37 sensors, 45 sensors (horizontal element, impulse).

Specification/Notes:

• Voltage: 3.3V to 5.0V
• LED: Power
• Size: 20mm X 60mm

There are a number of different sources for these modules. Not every module that looks similar to the ones here behaves exactly the same. Check the specific module that you have for differences in function, voltage levels, pinout, and inactive/active states. Some modules have been found to have incorrectly labeled pins and even poorly soldered components.

The module may include a 10kohm resistor that can be used as a pull-up or pull-down resistor.
