Devices dedicated to this purpose can be pricey in and of themselves, but enterprising Arduino users have created a brilliant answer. Here's how modders created a home energy monitor from an ...

11:25 am June 17, 2020 By Julian Horsey Lucía Garbo has created an Arduino powered noise pollution monitor, powered by an Arduino Mega micro-controller and housed in a 3D printed case.

Still, it's a handy project if you need to monitor and track the air quality in your home. Hit up the link below for the Arduino source code, a build guide, and all the details of the tests.

An Arduino Uno provides the processing power and drives the serial monitor. A joystick and a Hitachi H48C accelerometer are mounted on a breadboard and wired to the Uno.

Why lug around your PC when you can make your own External Serial Monitor! [ARPix] built this fully functional serial monitor based on an Atmega328 and a 102 x 64 LCD display.
