TIDM-AIRQUALITYSENSOR

MSP430FR4133 Microcontroller Air Quality Sensor Reference Design

TIDM-AIRQUALITYSENSOR

Design files

Overview

In this reference design, a simple air quality monitor is created and implemented using the particulate matter 2.5 level. This design uses MSP430FR4133 microcontroller (MCU) and Sharp™ DN7C3CA006 PM2.5 sensor. This ultra-low-power centric design of the MSP430™ MCU coupled with DN7C3CA006's integrated analog works in tandem to capture air samples and calculate the air quality index (AQI). From periodic PM2.5 samples, the AQI is calculated and displayed using an 8-character, 14-segment LCD.

Features
  • Calculates PM2.5 concentration levels and AQI levels
  • Calculates temperature and humidity levels
  • Offers an 8-character, 14-segment LCD to display calculation results
  • Uses an ultra-low-power MSP430FR4133 MCU with an integrated LCD controller
