Overview
This Dust Sensor gives a good indication of the air quality in an environment by measuring the dust concentration. The Particulate Matter level (PM level) in the air is measured by counting the Low Pulse Occupancy time (LPO time) in given time unit. LPO time is proportional to PM concentration.
This sensor can provide reliable data for air purifier systems; it is responsive to PM of diameter 1μm.
Note: This sensor uses counting method to measure dust concentration, not weighing method, and the unit is pcs/L or pcs/0.01cf.

„Alexa, who is at the door?“ - A face recognizing Arduino camera using AWS Rekognition for my grandmother
I created this project and my target is improve the comfort of my home. Taking a look around I noticed that home automation solution proposed by the big market player are too much expensive for me and, above all, I should create new wires connections between light, plug, etc.. and the control box.My idea is use what we already have without spend lot of money to buy a owner solution, so I started with arduino, my android mobile phone, some relays and my home.I have a nice home, 2 bad rooms, kitchen with living room and it was very nice tka e the control of the lights, gate and door with my mobile phone. [Mattia] have realized home automation via internet, using: [...] an Arduino 2009 with ethernet shield and the game is very easy, I send some http message to arduino, he moves some relays and give me back a JSON response. Not so hard, but the hard business is interfacing with the electrical wiring of home, with some patience I found what I need and I linked those wires at the relays. A chi non è mai capitato di restare chiuso fuori casa senza le chiavi? Beh a noi spesso e ci sarebbe piaciuto aprire il nostro cancello o porta di ingresso usando il telefono cellulare che abbiamo sempre con noi, il bisogno aguzza l'ingegno...ed ecco fatto! Ci siamo guardati un attimo in giro ed abbiamo recuperato un po' di informazioni su Arduino, la sua filosofia a "brick" ci è sembrata l'ideale per fare quello che avevamo in mente, il mio HTC Hero con Android OS ha fatto il resto. [Mattia] ha realizzato un progetto di automazione domestica usando Arduino Duemilanove e Ethernet Shield: [...]Bisogna far comunicare Arduino con il nostro telefono, la soluzione più pulita che mi è balzata in mente era quella di usare il protoccolo http per farsì che la comunicazione avvenga e JSON per scambiarsi i dati agilemente.
