I want to start a project at home and because the start has to be good, i need some help by choosing the right components.
First i want to build a smoke system = > an arduino with a smoke sensor MQ2 / DHT22 and a buzzer (so i get notified) in several rooms when there is an alarm i get a mail.
a weather station so i can program when i need to close the sun protection, so one smoke detector has to commucate with the weather station for the weater conditions and with an other arduino for closing relais (motor sun protection)
and maybe after a while some lights ....
i want to control the hole system with gsm or internet.
first i have to make a webserver ( ethernet shield and an arduino uno ?) for all the smoke sensors an arduino nano with esp8266 or ethernet ENC28J60 ?
i'm i making the right choices for the webserver and the smoke sensors?
