LD15 Laser PM2.5 Dust Sensor Model Product Details
Product overview
Particle sensor pm2.5 LD15 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.
LD15 Laser PM2.5 Dust Sensor Model
Working principle
laser sensor LD15 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.

1. Module List
HPD05 Module
2. Product Overview
HPD05 PM2.5 Sensor Module use principle of optical scattering to measure concentration of dust inthe air,the module built in a Infrared Transmitter and a high sensitive Photoelectric Receiving Sensor the Infrared Transmitter emits light and the light meets the dust to produce the scotch light, theintensity of the scotch light detected by Photoelectric Receiving Sensor reflects the concentration ofdust in the air, HPD05 have two ways to output current concentration data, one is PWM signal (thewidth of signal is the value, 1ms = 1ug/m3), the other is IIC signal(unit is ug/m3).
HPD05 can be used for Air Cleaner, Air Conditioner with purifying function, Fresh Air System and air quality testing equipment.
3. Detecting Principle
Detecting Principle
Per the principle of optical scattering,the Transmitter emits light, and the light meets the dust to produce the scotch light, the high sensitive Photoelectric Receiving Sensor detects the intensity of the scotch light then output intensity signal, current which is proportional to the size and quality of intensity of the scotch light, the current is amplified by amplifier and calibrated by CPU, finally output digital PWM signal or IIC data of concentration of dust.
