Temperature and Humidity Monitoring with Adafruit IO

This project shows you how to send temperature and humidity telemetry to Adafruit IO using the LYWSD03MMC and a Raspberry Pi. Using Bluetooth communication we find the broadcast of the LYWSD03MMC and communicate its readings to Adafruit IO. It’s a cute little temperature and humidity sensor with LCD display as...

AQI monitoring with Adafruit IO

Air Quality Index (AQI) uses pollutants such as Particulate Matter 2.5 microns (PM2.5) to indicate air quality. This is a topic that I have been interested in for quite a while as PM2.5 is an important indicator of air pollution. It is invisible, yet it can cause serious health effects.... [Read More]

PIR Activated Cam

This project records videos whenever there is any motion detected. This could be used as a security camera for your snacks, a backyard wildlife monitor, and more. My Raspberry Pi had some issues with its GPIO pins and I also learned that some specific sensors do not work well with... [Read More]

ZotBins Community Edition (ZBCE)

A continuation of the ZotBins Project, called ZotBins Community Edition (ZBCE), an open-source project. I further work with the ZotBins team at UCI to help expand the concept of ZotBins where any city, business, university, classroom, or home could implement a smart waste metrics system. [Read More]
