product description

A power relay module is an electrical switch that is operated by an electromagnet. The electromagnet is activated by a separate low-power signal from a micro controller. When switching off the current to the coil, the armature is returned, by force, to its relaxed position.

The relay module is an electrically operated switch that can be turned on or off deciding to let current flow through or not. They are designed to be controlled with low voltages like 3.3V like the ESP32, ESP8266, or 5V like your Arduino.

    A buzzer or beeper is an audio signaling device, which may be mechanicalelectromechanical, or piezoelectric (piezo for short). Typical uses of buzzers and beepers include alarm devicestimers, and confirmation of user input such as a mouse click or keystroke.

    Sensor-Buzzer is a passive buzzer. Like a magnetic speaker, it needs voltage with different frequency so that it can make sound accordingly. The pitch becomes louder when the frequency gets higher.

    The vibrating disk in a magnetic buzzer is attracted to the pole by the magnetic field. When an oscillating signal is moved through the coil, it produces a fluctuating magnetic field which vibrates the disk at a frequency equal to that of the drive signal.
