DESCRIPTION

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 higher the frequency, the finer the droplets. Usually, the droplets are guided into the air with a blower. It can be used to make a variety of products such as humidifiers.

This product is an ultrasonic water atomization module. It provides a maximum power of 10W and a water shortage detection function to prevent the transducer from being damaged when working in the absence of water. The module needs an external 24V power supply to drive the transducer and the blower. The module has a 5V voltage regulator IC that supplies power to the MCU.

The 5x2 pin header on the module provides additional functions such as atomization power adjustment, water shortage protection, RGB LED driver, communication interface (1-wire bus) and module status output.

The piezoelectric transducer we provide is 1.7MHz, 20mm diameter (not including the outer ring rubber sleeve). The module also supports 2.4MHz transducer, please set the correct frequency (JP5 on the module) before use.

The water shortage detection function uses the induction capacitance of water to decide water level; the more the water, the higher the capacitance value. The water level threshold can be set through the module pin or the 1-wire bus communication interface. When the capacitance is under the threshold, the module will stop making mist and output the module status pin accordingly. Refer to the Operation Guide for details on deciding the water level threshold.

This module can work in stand-alone mode or with an external host MCU. Through the 1-wire bus, the host MCU can read/write parameters of the module, such as water level detection, atomization power control, fan power control, etc. For details, refer to the 1-wire bus communication protocol and example program (Arduino).

To use this module, you have to prepare a 24V power supply. And if you want to connect a blower to the module, use a 24V blower. The water shortage detection spring should be placed close to the bottom of the water container. It is recommended that you decide the appropriate device first.
