Laundry Room Monitor


This started as a quick project to provide an alarm and phone notification when a water leak was detected in our second floor laundry room. A couple of years ago the drain hose from the washer somehow came out of the drain and the water made a bit of a mess in the living room below. In a classic case of scope creep (and a reluctance to dedicate an Arduino to just this one task) it ended up as a more comprehensive laundry room monitor that:

  • Does the leak detection and notification
  • Monitors the dryer vent for an over temperature condition
  • Monitors power consumption (and thereby cost) of washer and dryer operation (for each cycle and on a running total basis)
  • Provides notification of washer and dryer cycle completion
  • Provides detailed information on washer and dryer cycle progress
  • Provides a system to notify and record the need to replenish detergent and dryer sheet supplies

All this is implemented with an Arduino, the nifty Blynk app and a variety of sensors.
