Built-in Cubic auto particle identification technology for accurate measurement in different dust source environment. ■ Patented...

Specifications Outdoor Laser Particle Sensor Module PM3006S Specification

Dnve Circuit Dust flow Amplifier Circuit According to the diagram above, the light source part of PM3006S is composed of a laser diode that emits light to detect particles and a drive circuit. The detection part is composed of a photosensitive part that receives scattered light and an amplifier circuit. Data processing and communication output are completed by a microprocessor. PM3006S's particle detection is that the fan operates to generate air flow, and the particles pass through the detection chamber, the light from the laser tube will be scattered by the particles and converted into electrical...

Structure and Pin Definition Table 1. Connector Pin Definition Connector Description The interface connector of sensor is A2501WV-8P. The pitch is 2.5mm. The connection cable with female connector at both ends can also be customized.

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♦ UART Communication Protocol1. General Statement 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:

4.1 Read Particle Measurement Result Function: Read concentration of particle and particles number. Note: Read particle concentration (ug/m3)_ DF49: Alarm of sensor module working condition: 1. Laser tube failure alarm temperature temperature revolving revolving alarm alarm Note: Part of reserved bit is used for internal testing. Reserved bit is not related to function www.gassensor.com.cn

4.2 Open/Close Particle Measurement 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...

4.5 Read Serial Number

Communication Protocol♦ I2C Communication Protocol1. Brief Introduction a. This is an IIC protocol for PM3006S. 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...

Package Information Table 3. Packing

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 the way shown in figure 2. Figure 1. Sensor Internal Section View Figure 2. Recommended install

User Attentions ※ The air inlet inside diameter of user equipment should not be less than the sensor’s air inlet diameter ※ When use the product, it is recommended to add a 50-60 mesh protective filter to the sensor's air inlet to prevent flocs, hair, etc. from affecting the sensor's detection. ※ The product is an integral unit that shall not be disassembled to avoid any irreversible damages. ※ This product is defined as 3B laser product according to GB7247.1-2012 Laser Product Safety with laser radiation inside. Please avoid direct illumination on the eye. The warning signs are as follows: After-Sales...
