Optimizing power consumption has been a problem for us in the past.

For this purpose, one of our developers took the initiative to construct a Data Logger using a WEMOS D1 mini.

The purpose of this IoT project was to:

  • Monitor power consumption at the premises.
  • Identify data patterns and use it to reduce utility costs.
  • To eliminate any redundant power consumption.

List of Components Used

  • WEMOS D1 Mini Development Board (Includes ESP8266 WiFi Module)
  • Burden Resistor 33 ohm
  • 4051 Multiplexer for the purpose of extending the analog inputs for reading 3 phases
  • 1 LED
  • 10K Resistor

WEMOS D1 mini as the Wi-fi capable development board with 4MB flash based on ESP-8266EX.

We used Thingspeak for the purpose of data logging, tracking & updating data.

It’s an open source IoT analytics service which allows you to have a dashboard for analyzing live data streams in the cloud, coming through your IoT device.

You can read the full article here with an in-depth explanation of how this Data Logger was installed on our premises.

Feel free to tell us what you think about it. Cool
