BST Sensors’ PM2.5 Sensors category covers optical particle-sensing modules for automotive air purification, HVAC equipment, purifiers, fresh-air systems, detectors, and related OEM products. Particle-sensor selection should consider the detectable size range, reported outputs, accuracy range, response and stabilization time, airflow path, power consumption, communication interface, installation orientation, humidity exposure, and maintenance strategy. For system context, see our guide to cabin air quality monitoring.
Projects prioritizing cost, low power, and general particulate trends can review the BST infrared dust sensor. Applications needing finer particle resolution and simultaneous particulate outputs can compare the laser dust sensor. Neither sensing method should be selected by principle alone: enclosure airflow, optical contamination, condensation, nearby fans, electromagnetic noise, firmware filtering, and calibration conditions can materially affect field performance. Validation should therefore use the intended mechanical design and representative environmental conditions.
HY-B62 all-in-one air quality monitoring system can simultaneously measure a variety of gas indicators, including laser dust sensor, CO2 sensor, TVOC sensor and temperature and humidity sensor.
The data is output in the form of a digital interface.
