photoacousticfor air quality monitoringmonitoring

Photoacoustic Spectroscopy CO2 Sensor (PAS CO2 sensor for short) is a cutting-edge product that employs photoacoustic spectroscopy to fulfill the high-end market demand. The sensor modulates light based on Lambert-Beer's law, causing the targeted gas molecules to undergo pulsation and generate acoustic vibrations. These acoustic vibrations at particular frequencies reveal the carbon dioxide levels. Featured with its small size and high precision, the sensor is ideal for detecting varying concentrations of CO2. Application HVAC, Air purifiers, Indoor CO2 monitors Features •The latest technology •UART output to detect CO2, temp.&hum. •Small size and SMD assembly allowed •Fast response and high accuracy •Low power consumption
