Keyes

The Keyes KY-002 module features an omnidirectional vibration sensor based on the SW-18015P spring switch, which responds to shocks and vibrations coming from any direction.

The Keyes KY-003 module is a digital Hall effect sensor designed for non-contact magnetic field detection.

The Keyes KY-006 module with a passive buzzer allows for the generation of audio signals with an adjustable tone – unlike an active buzzer, it requires a PWM signal input

The Keyes KY-008 laser module with a red beam (650 nm) is designed for projects with Arduino and other development boards.
