Product Name: Laser Particle Sensor Module Item No.: PM3003S Version: V0.1 Date: 5th, March 2021

Laser Particle Sensor ModulePM3003S CUBIC ■ Outdoor Air Quality Monitoring ■ Construction Site Monitoring ■ M i ning Site Monitoring ■ Environment Monitoring Alarm System PM3003S is a linear light source-based particle sensor module with laser scattering technology. It is designed to measure the quantity per unit volume of different particle size and can output particle mass concentration PM1.0, PM2.5, PM10 and TSP in gg/m3 at the same time via mathematical algorithm and scientific calibration. Built-in Cubic auto particle identification technology with customer external stable flow air pump,...

Specifications CUBIC © Wuhan Station traceability system as benchmark. If there is measurement discrepancy in other regions, coefficient correction is needed based on the local dust particle distribution. Note: www.gassensor.com.cn

Structure and Pin Definition CUBIC Table 1. Connector Pin Definition Connector Description The interface connector of sensor is A2501WV-8P. The pitch is 2.5mm.

Case 2. I2C TTL 3.3V Output Note of Circuit Design ■ UART and I2C communication compatibility with 3.3V and 5V level (receiving end). ■ Pin 8 is the pin for manufacturer testing, should be floating in the application circuit.

Communication Protocol CUBIC 1) The data in this protocol is all hexadecimal data. For example, “46” for decimal [70]. 2) [xx] is for single-byte data (unsigned, 0-255); for double data, high byte is in front of low byte. 3) Baud rate: 9600; Data Bits: 8; Stop Bits: 1; Parity: No 4) It is default by continuously mode after powering on. Working mode will not be saved after powering off. Sending format of software:

4. Detail Description of UART Protocol 4.1 Read Particle Measurement Result Function: Read concentration of particle and particles number. Note: Read particle concentration (pg/m3) Alarm tube failure . ,ou ing temperature temperature definition alarm alarmalarm alarm Note: Part of reserved bit is used for internal testing. Reserved bit is not related to function

Send: 11 03 0C DF1 1E CS Response: 16 02 0C DF1 CS Function: Open/ close particle measurement Note: 1. When sending command, DF1=2 means opening measurement, DF1=1 means closing measurement; 2. When receiving response, DF1=2 means measuring opened, DF1=1 means measuring closed; 3. When the sensor receives the command of opening measurement, it will be in default continuous measurement mode. Example: Send: 11 03 0C 02 1E C0 //open particle measurement //module is under particle measurement open status //close particle measurement // module is under particle measurement closed status 4.3 Set up...

Communication Protocol CUBIC a. This is an IIC protocol for PM3003S. The sensor module is lower computer, which is not able to initiate communication automatically. Communication is initiated via main controlled board, which reads data and sends control commands. b. I2C communication clock frequency <=100Khz START: start signal, send by main controlled board; STOP: stop signal, send by main controlled board; ACK: acknowledge signal, send by the sensor module if in bold; otherwise, send by main controlled board; NACK: non-acknowledge signal, send by the sensor module if in bold; otherwise, send...

Package Information CUBIC

Product Installation When the sensor is installed and used in user’s system, it should ensure that the airflow at the sensor’s air inlet and outlet is unobstructed. To ensure sensor’s measurement accuracy, the surface of sensor sensitive elements as shown in figure 1 shall be protected from dust depositing. It is recommended to install the sensor in user’s system following installation recommendation shown in figure 2. The blue surface represents the front of the lens Light reflection convergence area The blue surface represents the front of the photosensitive sensor Figure 1. Sensor Internal...

User Attention ※ The recommended length of the air inlet duct is less than 20cm, and the recommended material is fluorine rubber. ※ It is recommended to use compressed air to clean the sensor regularly during the use of the product to prevent the contamination of flocs, hair, etc. from affecting the sensor detection. ※ Sensor is an integral unit. In case of irreversible damage, the sensor cannot be disassembling. ※ This product is defined as 3R laser product according to GB7247.1-2012 Laser Product Safety with laser radiation inside. Please avoid direct illumination on the eye. The warning signs...
