Hi,
I’m working on a project with the Grove Water Atomizer, and I have a couple of technical questions about the setup:
- What is the atomization rate of the atomizer when the driver board is powered with a 5V supply?
- What is the voltage supplied to the transducer plate when the supply to the driver board is 5V?
- Could you please provide the specific model and manufacturer of the ultrasonic transducer plate used in the atomizer?
Thank you for your help! I appreciate any details you can share about the hardware.
Best regards
Hi there,
So from the schematic and WiKi and AI, I see 5v boost to 16Vdc and a Freq. of 105±5kHz from the 555 timer chip PWM the rate of atomization is said to be the following:
When powered by a 5V supply, a typical ultrasonic atomizer will have an atomization rate ranging from around 200mg/hour to 500mg/hour depending on the specific atomizer design and operating conditions, with most falling within the 300mg/hour range.
Key points to remember:
-
Atomization rate is measured in milligrams per hour (mg/h): This indicates the amount of liquid converted into mist per hour.
-
Factors affecting atomization rate:
-
Driver board frequency: Higher frequencies generally produce a finer mist and higher atomization rate.
-
Atomizer disc size: Larger discs can produce a higher volume of mist.
-
Water quality: Impurities can affect the atomization efficiency.
-
Operating temperature and humidity: Environmental conditions can also impact the atomization rate.
We don’t know the disc size YET and the Schematic only show a number.?? SEEED will need to chime in…

Hi there,
Cool subject… the typical Amazon unit has specs of
Parameters:
1.Work Voltage:DC 4.5V~5.0V (Seeed/Groves is 16Vdc)
2.Work Power:2W
3.Power Type:Female Micro USB Socket
4.Spray Diameter:5um
5.Spray hole:740 holes
6.Spray speed:50ml/h (108Khz) 20mm round
7.Work Temperature:0℃~85℃
8.Work Humidity:10%~90%RH
9.Driver Size:351915mm
Application:
1.USB humidifier
2.Perfume atomizer
3.Aromatherapy atomizer
4.Auto parts
5.High-end toys with large amount of humidifier
It has Lower output when compared to the seeed unit which I believe is better than the Amazon unit.
