Fasizi SDS011 PM2.5 PM10 Air Quality Detection Sensor Module Digital Output

Fasizi SDS011 PM2.5 Air Quality Detection Sensor Module

This high-precision sensor module from Fasizi is designed for detecting PM2.5 and PM10 particulate matter in the air. It features a digital output and utilizes a serial communication protocol for easy integration into various projects and systems.

Key Features

• High Precision: Accurately detects PM2.5 and PM10 concentrations.
• Digital Output: Provides data via serial communication.
• Serial Communication: Uses UART (9600 baud, 8N1) protocol.
• Wide Application: Suitable for air quality monitoring systems and DIY projects.

Specifications

Interface Pinout:

• CTL: Control pin (reserved)
• 1um: >0.3 Micron particle concentration (PWM Output)
• 5V: 5V power input
• 25um: >2.5 Micron particle concentration (PWM Output)
• GND: Ground
• R: Serial port receiver (RX)
• T: Serial port transmission (TX)

Interface Pitch: 2.54mm

Communication Protocol:

• Serial Protocol: 9600 8N1 (9600 baud rate, 8 data bits, no parity, 1 stop bit)
• Serial Report Cycle: 1 + 0.5 seconds
• Data Frame (10 bytes): Message Header + Order + Data (6 bytes) + Checksum + Message Trailer

Data Frame Structure:

• Byte 0: Message Header (AA)
• Byte 1: Order (C0)
• Byte 2: PM2.5 Low Byte
• Byte 3: PM2.5 High Byte
• Byte 4: PM10 Low Byte
• Byte 5: PM10 High Byte
• Byte 6 & 7: Reserved (0)
• Byte 8: Checksum
• Byte 9: Message Trailer (AB)

Data Calculation:

• PM2.5 Concentration (ug/m3): ((PM2.5 High Byte * 256) + PM2.5 Low Byte) / 10
• PM10 Concentration (ug/m3): ((PM10 High Byte * 256) + PM10 Low Byte) / 10

Package Included

• 1 x Fasizi SDS011 PM2.5 Air Quality Detection Sensor Module
