Introduction for Air Filter
The PCB Assembly for Air Filter is a core electronic control component specifically designed for air purification equipment. It integrates a printed circuit board (PCB) with various electronic components (such as sensor chips, microcontrollers, relays, capacitors, resistors, etc.) through soldering and SMT processes. Its core value lies in its highly integrated "perception-analysis-control" functional modules for air filters, replacing traditional decentralized circuit designs and achieving miniaturized, precise, and stable device control. Unlike general-purpose PCB assemblies, this product is customized for air filtration scenarios, including pre-reserved interfaces for dust sensors and formaldehyde detection modules, as well as protective features (such as moisture-proof coatings and high-temperature-resistant components) to meet the high-temperature and high-humidity environments within air purifiers.
This component is the core hub for the air filter to achieve "intelligent purification" and "efficient operation", and it mainly undertakes three key functions: first, environmental data collection and analysis. By connecting to PM2.5, TVOC, temperature and humidity sensors, it receives air quality data in real time, and the built-in microcontroller performs calculations and analysis on the data to determine the current pollution level; second, intelligent control of the purification module, automatically adjusting the fan speed, activated carbon filter switching frequency or UV sterilization lamp start and stop according to the pollution level. For example, when the PM2.5 concentration is detected to exceed the standard, the fan is immediately triggered to run at high speed to improve purification efficiency; finally, status feedback and safety protection, through the LED display module or APP linkage, feedback to the user on the filter life and equipment operating status, and it also has overcurrent protection and overload protection functions. When the circuit is abnormal, it automatically cuts off the power supply to avoid equipment damage or safety hazards.

Product Applications
1. In home settings, PCB Assembly For Air Filter integrates a PM2.5 sensor, a formaldehyde sensor, and a fan control module to monitor air quality in living rooms, bedrooms, and other spaces in real time. When smog or renovation pollution is detected, it automatically adjusts the filter's operating power and pushes data via a mobile app (e.g., switching to silent mode when PM2.5 concentration is <10μg/m³). For example, the PCB component of the Xiaomi Mijia air purifier utilizes a similar solution, enabling full-link intelligent control in "auto mode."
2. In large spaces such as shopping malls and office buildings, this component serves as the control core for central air conditioning terminal purification units and supports multi-sensor networking (e.g., deploying 10+ air quality monitoring nodes per floor). By analyzing data such as CO₂ concentration (>1000ppm activates strong exhaust) and TVOC content, it coordinates with the fresh air system to adjust air supply volume. It also features fault self-diagnosis (e.g., automatic alarm if the filter pressure differential sensor is abnormal). The air purification system of the Shanghai Tower utilizes this customized PCB solution.
3. In industrial environments such as welding workshops and cement plants, this component must withstand high temperatures (-40°C to 85°C) and strong electromagnetic interference. It integrates a laser dust sensor and explosion-proof relay. It analyzes dust concentration (for example, high-voltage electrostatic dust removal is activated when PM10 > 5mg/m³), controls the variable frequency operation of the dust collection fan, and includes an RS485 interface for integration with the factory's SCADA system. Sany Heavy Industry's welding workshop dust removal equipment utilizes this industrial-grade PCB solution.
