HVAC systems are also called air conditioning systems. Their functions include controlling temperature, humidity, air cleanliness, and air circulation, similar to the principles of standard air conditioners or central air conditioning. In the past, HVAC systems were started manually, operating when the switch was turned on and shut down manually when not needed. The main issues with this were the lack of intelligence and low energy efficiency.

The working principles of HVAC systems and air conditioners for providing cooling, heating, or dehumidification are similar; they use refrigerants that evaporate or condense under the action of a compressor, triggering the evaporation or condensation of surrounding air to change temperature and humidity. Modern HVAC systems are generally more intelligent, equipped with various sensors such as temperature sensors, humidity sensors, and dust sensors. When the data detected by sensors reaches the system threshold, the corresponding adjustment function starts. When the environment reaches an ideal state, the system returns to standby mode, which is much more convenient and energy-efficient.

The HPD05 infrared dust sensor is a high-precision dust sensor capable of detecting particles with a diameter of 0.5 micrometers. it can directly output concentration values with high consistency and has obtained multiple domestic patents.
