Air Monitoring Breakout

Air Monitoring breakout for Raspberry Pi, an open-source portable sensor that can provide the level of quantity of the suspended particulates with their mass. Air Monitoring breakout has a powerful and hi-tech PMSA003 sensor that provides the information of suspended particulate matter(PM1.0, PM2.5, PM10) in the air per unit volume via digital output with an operating voltage of 3.3 V. It communicates via UART(serial) with the standby current ≤200 Microampere(μA) of the sensor. It is compatible with Raspberry Pi, Beaglebone, Arduino, STM32, PIC, AVR, ARM, etc.

RESET Module reset signal /TTL level@3.3V,low reset.
SET Set pin /TTL level@3.3V,high level or suspending is normal working status, while low level is sleeping mode.

Installation

Arduino

  • Arduino Library for PMSA003 Air monitoring Breakout.

Air monitoring breakout Library

Raspberry Pi

  • Connect Air Monitoring Breakout with Raspberry Pi as mentioned in below pinout.
Pinout Raspberry Pi (BCM)
VCC 5V
GND GND
RX GPIO14
TX GPIO15
RESET GPIO17
SET GPIO27
  • Open a terminal and run the following commands to enable Serial:
sudo raspi-config

And choose Interfacing Options -> Serial -> No -> Yes
