[CN] Luftmy LD11 Laser PM2.5 Dust Sensor Module Jul 22, 2021

Product overview
Laser dust sensor module LD11 is a high-precision particle sensor based on the theory of laser MIE scattering. It can continuously collect and calculate the number of suspended particles with different particle sizes in air per unit volume, that is the concentration distribution of particles, and then convert to mass concentration. And output in the form of universal digital interface.

The sensor can be embedded with various instruments related to the concentration of suspended particulates in the air or environmental improvement equipments to provide timely and accurate concentration data.

LD11 Laser PM2.5 Dust Sensor Model

Working principle
laser sensor module LD11 adopts MIE spherical particle scattering principle, that is, laser sensor uses laser to irradiate suspended particulate matter in the air to produce light scattering, photoelectric detector collects scattering light intensity in a certain angle range, the scattering light intensity will be linearly converted to voltage, and then sent to data processing system, the data processing system take the principle of Michaelis scattering theory to deal with the datas, then the equivalent particle size and the number of particles with different particle sizes per unit volume are obtained.

Main feature
1 High measure accuracy up to 0.1μm

2 Zero error alarm rate

3 Real-time response and support for continuous data collecting

4 Minimum resolution particle size 0.1μm

5 Electronic controlled devices lifetime > 8 years, average working time > 5 years.

6 Wide range of application, no need for air duct design, compatible with multi-protocol output

7 light and thin design, suitable for detectors, wearerable equipments, air purifiers, fresh air systems, etc.

8 Six-sided shielding combined the software anti-jamming algorithm, with higher anti-jamming performance

Typically Application
(1) Particle monitor instruments

(2) Environmental improvement equipments

Product Specification
laser dust sensor module Product Specification

Note 1 : Maximum range means that this sensor ensures that the maximum output value of pm2.5 standard value is not less than 1000 u g / m3. when the data is > 1000 u g / m3. pls take the actual measure value .

Note 2 : the consistency data of the particle concentration is the data in the appendix -Measuring temperpture condition is 20℃,humidity condition is 50% .
