The LD19 is a high-precision particulate matter concentration sensor based on the Laser Mie Scattering theory. It can continuously collect and calculate the number of suspended particles of different sizes in the air per unit volume—namely the particulate matter concentration distribution—and convert this into mass concentration, outputting it via a universal digital interface. This sensor can be embedded in various instruments or environmental improvement equipment related to suspended particulate concentration to provide timely and accurate data.
The LF12 is a sensor that does not require an internal fan; its driving air source comes from the host device, which overcomes the defects caused by fans in traditional laser sensors on the market. A high-illuminance and uniform light-sensitive area is set in the center of the scattering cavity inside the housing. A semiconductor laser generator and detector are set outside the scattering cavity. The detector is connected via an amplification circuit to a microcontroller unit that can calculate the particle diameter and quantity based on the amplification circuit’s input signals.
LD12 series is a high-temperature resistant, long-life laser dust sensor. Based on optical scattering and Luftmy's unique dust source identification technology, it accurately calculates suspended particles of different sizes.
The LD09 series is a high-temperature resistant, long-life, ultra-thin laser dust sensor. Based on the principle of optical scattering and combined with LUFTMY's unique dust source intelligent identification technology, it can accurately detect and calculate the number of particles of different sizes in a unit volume across various environments. Through mathematical algorithms and scientific calibration, it achieves accurate PM2.5 mass concentration output. The full metal shell effectively shields electromagnetic interference.
