Spray Mist Device PCBA – Ultrasonic Atomizer or Steam Generator Circuit Board with Adjustable Mist Output, LED & Battery Management
- Dual Atomization Technologies – Supports Ultrasonic High‑Frequency Atomization (1.7MHz–2.4MHz Ceramic Disc) for Fine Cool Mist (2–5µm Particle Size), or PTC Heating Steam Generation (up to 8W) for Warm Vapor. PCB Configurable for One or Both Modes.
- Adjustable Mist Output – PWM‑Controlled Mist Intensity with 3–5 Preset Levels (Low/Medium/High) or Stepless Knob Control. Ultrasonic Version Achieves 20–60 mL/Hour Fog Output; Steam Version Delivers 10–30 mL/Minute Steam Flow.
- Smart Water Management – Integrated Water Level Detection (Dual‑Probe or Floating Magnet Sensor) with Low‑Water Auto‑Shutdown to Prevent Dry Running or Overheating. Anti‑Leak Protection and Overflow Cut‑Off.
- Battery & USB Charging – Built‑in Li‑ion Charging Circuit (USB‑C or Micro‑USB, 5V/1A–2A) with Over‑Charge, Over‑Discharge, and Short‑Circuit Protection. Supports 1S (3.7V) or Optional 2S (7.4V) for High‑Power Steam Applications. Standby Current <20µA.
- Compact UI & Optional Features – Single‑Button or Capacitive Touch Control (Short Press = Mist On/Off, Long Press = Intensity Adjust). Multi‑Color LED for Power/Water Level Indication. Optional 0.96″ OLED Display, Bluetooth App Control, or Voice Module Integration for Smart Humidifiers.
