Microcontroller Jobs

I have an IoT project that simulates the smart meter concept : I have sensors to measure the voltage, current and watts. The project uses esp8266 to send data to thingspeak and Adafruit. I use my website to turn on/off the lights and to show the voltage, current and watts by using thingspeak Iframe. I want to have a database that records the watts in hourly basis to calculate the consumption a...
