Introduction

nodemcu-reservoir is a bucket with water pump that buffers water from an air-condition. The purpose is to buffer the water during daytime and pour in the midnight. But Why? Here is the scenario,

  1. We have a room of servers.
  2. Our office building do not provide professional air-condition device for those servers
  3. Though we are allowed to install our own air-condition, we are not allowed to let the water flow out of window during the daytime.

We made this bucket (mostly for fun) to buffer the water during daytime and use a crontab to trigger a pump in the midnight to let the water go. Here are some photos of the device,
