Indoor Air Quality Monitor: Concept and Implementation
Ankit Phougat, Namrata Dalvi
This application note describes the design and implementation of the Indoor Air Quality Monitor (AQM) using Core Independent Peripherals (CIPs) and intelligent analog peripherals of the ATmega4808 microcontroller (AVR® MCU) featuring the 8-bit AVR processor. Microchip’s CryptoAuthentication™ secure element (ATECC608A) and a fully certified Wi-Fi® module (ATWINC1510) are used to securely connect the smart AQM to the Google Cloud™ IoT Core platform. The firmware is available on GitHub (Indoor Air Quality Monitor – Atmel Studio, and [Indoor Air Quality Monitor – MPLAB ® X|https://github.com/microchip-pic-avr-examples/atmega4808-air-quality-monitor-mplab.git]). This appnote is supported by [AN3417|http://www.microchip.com/DS00003417] and [Indoor Air Quality Monitor: User guide|http://www.microchip.com/DS50002966] documents.
