NOVA PM SENSOR SDS011 HIGH PRECISION LASER PM 2.5 AIR QUALITY DETECTION SENSOR

160 ر.ق

  • The SDS011 using the principle of scattering can get the particle concentration between 0.3 to 10um in the air. It with digital output and the built-in fan is stable and reliable.
  • Accurate and Reliable: detection, stable, good consistency; Quick response: response time is less than 10 seconds when the scene changes.
  • Easy integration: UART output (or IO output can be customized), fan built-in; High resolution: the resolution of 0.3ug/m3.
  • Scope of application: PM2.5 Detector; Purifier; Air Exchangers; Filtering system.
  • Working principle: Using scattering principle: Light scattering can be induced when particles go through the detecting area; The scattered light is transformed into electrical signals and these signals will be amplified and processed

Description

This product supports 5V power supply voltage, output signal TTL

If 5V, higher than this voltage, the product will burn out,

Please remember!

This product uses the principle of laser scattering and can obtain the concentration of suspended particles in the air of 0.3 to 10 microns.

Remarks: The pitch of the interface is 2.54, and the 90-degree pin interface is used without special instructions;

Product specification

Product size: L*W*H=71*70*23mm

Protocol :

Serial communication protocol: 9600 8N1. (Rate 9600, data bit 8, no parity bit, stop bit 1)

Serial port reporting communication cycle: 1+0.5 seconds

Data frame (10 bytes): message header + instruction number + data (6 bytes) + checksum + message tail

Byte number name remarks

0 packet header AA

 

1 Instruction number C0

 

2 Data 1 PM2.5 low byte

 

3 Data 2 PM2.5 high byte

 

4 Data 3 PM10 low byte

 

5 Data 4 PM10 high byte

 

6 Data 5 0 (reserved)

 

7 Data 6 0 (reserved)

 

8 Checksum Checksum

 

9 Trailer AB

 

Checksum: the sum of bytes from data 1 to data 6.

 

PM2.5 data content: PM2.5(ug/m3) = ((PM2.5 high byte*256) + PM2.5 low word

 

Section)/10

 

PM10 data content: PM10(ug/m3) = ((PM10 high byte*256) + PM10 low byte)/10

 

1. First install the USB to TTL driver software;

2. USB to TTL serial cable, connect PM2.5 sensor, plug-in computer;

3. After power on, open the serial port debugging assistant software, select the serial port used by the USB to TTL serial line, and use the baud rate of 9600.
