The HX1047P2H0026A 4-Channel Ultrasonic Humidifier Driver Board is a high-performance, compact control solution designed to drive up to four ultrasonic atomizing transducers simultaneously. Built on durable 1.2mm FR-4 glass epoxy material, this driver board utilizes high-frequency electronic oscillation to convert electrical energy into rapid mechanical vibrations. When paired with microporous atomization discs, it breaks down water structure to generate a cool, ultra-fine mist without releasing heat. This makes it a popular choice for custom smart-home humidifiers, foliage plant misting networks, terrariums, and DIY automated fluid distribution projects. [1, 2, 3, 4, 5]

• Model Designation: HX1047P2H0026A
• Operating Voltage: DC 5V
• Rated Operating Current: ~300mA per active channel (scales based on nozzle deployment)
• Power Consumption: 2.5W to 3.0W under full load
• Resonance Frequency: 108kHz ± 2kHz (Optimized for standard 16mm/20mm microporous atomizing sheets)
• Interface Interface Standards: Dual-pin wire-to-board output terminals (PH2.0 style pitch)
• Board Dimensions: Extremely compact footprint measuring approximately 50mm x 25mm [1, 2, 5]

The integrated micro-controller handles multi-zone spraying operations via onboard tactile control switches, cycling through several misting patterns: [2, 6]

1. Continuous Quad-Spray Mode: Simultaneously fires all four output terminals to deliver maximum mist output. [6, 7]
2. Sequential Dynamic Misting: Alternates power systematically from nozzle 1 through nozzle 4. Each channel remains active for a 3-second pulse before handing off to the next channel, preventing local condensation. [6, 7]
3. Indirect Custom Spraying: Activates select channels (e.g., singular nozzle run or paired dual-nozzle layout) to fine-tune moisture generation rates based on room size. [6]
4. Integrated Smart Shutoff: Features a 2-hour automatic shutdown timer built directly into the firmware. This safeguards connected transducers against dry-firing or burning out when liquid wells empty out. [6, 7]

• Integrated Status Buzzer: Provides direct sonic feedback whenever mode shifts happen or system faults are triggered.
• Clean Mist Delivery: Designed to mesh with ultra-dense micro-aperture atomizers (typically featuring ~5μm laser-drilled pore walls) to guarantee maximum vertical mist suspension while keeping adjacent table tops dry. [1, 2, 8]
• Low Driving Impedance: Advanced solid-state design cuts down operational heat signature across the PCB footprint, ensuring a longer service life during prolonged runtime cycles. [2, 8]
