ESO8266 IoT

My new project consists of HW with cost under 20€. It is able to accurately measure electric power consumption and sends data via WiFi. Great source of knowledge is openenergymonitor.org which includes also Arduino library.

I successfully run DHT22 battery ESP8266 temperature/humidity IoT sensor so my next project is a simple IoT Door Sensor. It is up and running and sending a simple event to my HTTP server via wifi chip ESP8266 (ESP-01 in my case). HTTP server is serving simple php script, that stores the data locally and also sending events to DWEET.IO and also sending email via Amazon SNS (AWS CLI api).

I learned how to program ESP8266 so I created my first temperature IoT ESP8266 project. I used DHT22 as a temperature and humidity sensor and also I did some testing of power consumption using LIGHT SLEEP (LIGHT_SLEEP_T) mode on ESP8266.
