Our surroundings are constantly degrading, and there are innumerable disease that can be caused by living in unhealthy, impure and polluted surroundings. I know there are a number of devices in the market that will measure the concentration of harmful pollutants in your house. But, I decided to build one so, I get to choose the functionality I want.
He used anRF52382 board for BLE, a DHT11 for humidity and temperature monitoring and a Raspberry Pi. It sounds like a lot of parts, and it is, but [Vaishali] managed to build this, an enclosure, and used Adafruit IO to monitor it all.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
