DESCRIPTION

Differences between BM52D5021-1 and BMN31K502

The BM52D5021-1 has the same functions and specifications as the BMN31K502. The only difference between them is that the BMN31K502 includes a 5-pin cable for direct connection to the BMduino-UNO BM53A367A.

Generating mist

The product generates oscillations at a frequency of 108KHz using a piezoelectric ceramic ring on the piezoelectric transducer to create ripples on the water surface. Then water molecules get into the micro-holes on the metallic film of the piezoelectric transducer. Due to the small diameter of these micro-holes, tiny water droplets are expelled from the opposite side of the metallic film, forming a mist.

Atomizing levels and atomizing period

The product provides two operation modes, stand-alone and UART.

Stand-alone mode: you can easily control the atomizing power on/off by pressing the on-board button.
UART mode: connect the product to a development board via BMCOM to control the power on/off and can configure atomizing levels and atomization period by the development board.

Please connect the piezoelectric transducer before powering on to prevent the product from any damage.
