upcycling-interactive-humidifier

Let's make upcycling interactive humidifier with legacy humidifier and openHW

SW upcycling

Reuse Adafruit DHT unified sensor library sample.

Reuse Adafruit Neopixel library sample.

HW upcycling

Reuse a legacy humidifier

HOWTO

1. Upload combined upcycling-interactive-humidifier.ino to Arduino Nano.

2. Install neopixel strip to wall for humidity state notice with ambient color.

3. Install DHT11 sensor to wall for gathering humidity.

4. Connect Realy Multi Tap to legacy humidifier for interactive control.

5. Connect external 5V DC power supply for LED control.

6. Attach Home Humidity Board

• In our home, first daughter drew it after understood 5 level meaning.

Ambient Color Notice

• Humidity <= 20% : Red Color

• 20% < Humidity <= 40% : Yellow Color

• 40% < Humidity <= 60% : Green Color

• 60% < Humidity <= 80% : Cyan Color

• 80% < Humidity : Blue Color

Humidifier Relay Control

• Humidity <= 50% : Turn On Humidifier

• Humidity > 50% : Turn Off Humidifier

7. Now transform legacy humidifier to interactive humidifier

• Just check water tank of humidifier sometimes whether it's empty or not. :)
