IOT Alarm: First prototype

This is the first solution I built:

All the elements were commented before. I’ll share with you the Arduino code, but first some comments about this approach:

1. The solution is not a good approach. It had problems between ESP8266 and Servo. Both needs more power than the one provided than Arduino, and even both can’t use the same power source (not sure yet why).
2. I connected using an instance in thingspeak.com. And I detected the stability to detect the signal of some of the sensors was not good. But I guess it’s related to the code and not with the architecture.
3. After doing some researching about ESP-8266 I found there’s a powerful processor (also better than Arduino’s!). Also I’ll share with you my research.

The conclusion it’s a nice way to start with something to understand the interaction between Arduino and different kind of sensors. Tough It’s not a best stable alarm even for a hobbyist solution. So, I’m going to digging into the ESP-8266 + Arduino plugin + I2C to give more independence between both chips. Maybe I’d find something more reliable.
