product description

Humidity Sensor and Digital Temperature Module AM2302 is a basic, low-cost digital temperature and humidity sensor.

Humidity sensors work by detecting changes that alter electrical currents or temperature in the air.  A capacitive humidity sensor measures relative humidity by placing a thin strip of metal oxide between two electrodes. The metal oxide’s electrical capacity changes with the atmosphere’s relative humidity.

    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.
