One of the first DIY electronic projects I accomplished was building a multi-sensor that contained sensors for motion, temperature and humidity, a light level sensor and an RGB LED indicator. It was also my introduction to the ESP8266 NodeMCU. And while this multi-sensor has continued to run successfully for over three years, it does have some limitations. So, it's time to take some of the new skills and ideas that I've learned and create a new updated version. You can also watch a YouTube video of this project.
