This project use Arduino UNO and a current sensor called STC-013.
Arduino UNO read the value by the sensor, and after put the data on Cayenne Dashboard by using MQTT protocol.
You can see the value and monitoring the values in time.
Also you can trig the value. When the consumption goes up a threshold, you can send a mail to you or your family.
We really need to allow you guys to customize those notification emails. There are so many possibilities for the tone of email you might want to send out when someone leaves on all of the lights in the house…
