DESCRIPTION

The BM52O5221-1 is an integrated atomizer module. It integrates a piezoelectric transducer, control circuit board, and structural components.

The principle of an ultrasonic atomizer is to use the high-frequency mechanical oscillation of a piezoelectric transducer to convert the water particles into tiny droplets.

The product circuit is the external-driving type. Therefore, it has the advantages of high effect when atomizing, tiny size, and less heat generation. It’s suitable for applications of humidifiers, aroma diffusers, and other related products.

The BM52O5221-1 also provides a water-shortage detection function to prevent the transducer from being damaged when working in the absence of water.

PIN DESCRIPTION
OPERATION MODE AND WIRING

The BM52O5221-1 provides three types of operation mode: VR mode, PWM mode, and learning mode.

VR mode: Use the VR control board to interrupt the 24V power and turn off the atomizer.

Getting started

  1. Connect the module to 24V power, a fan, and the VR control board.
  2. The module detects the water level after powering on. The red LED turns on in the meantime.
  3. If the water level is detected to be higher than the threshold, the red LED turns off. Users can start the atomization after the green LED turns on.

PWM mode: Use the PWM control board to adjust the mist amount.

Getting started

  1. Connect the module to 24V power, a fan, and a PWM control board.
  2. The module detects the water level after powering on. The red LED turns on in the meantime.
  3. If the water level is detected to be higher than the threshold, the red LED turns off, and the green LED turns on.
    You can start to atomize with it.
  4. Press the spring on the PWM board to adjust the mist amount (three-level).

Learning mode: it can learn and memorize the status of no water.

Please note that the module needs to be completely dry in this mode. The product has been calibrated under this mode in the factory. Users do not need to calibrate it again. This mode is mainly for development uses.

PRODUCT FAQs

Question 1
What will happen if I use the module without a ring rubber gasket?

Answer
If the module is not compact with the structure, the water might be leaking.
Please refer to the ring rubber gasket pictures as below.
