This is the DIY Kit for the frischluft.works project.
frischluft.works is a CO2 Measurement device that has a RGB Led and a Buzzer and notifies you when it is time to open the windows and let some fresh air in.
The LED shines in bright green when the PPM (parts per million) is below a certain threshold and turns yellow if it rises above that value and plays a short notification sound.
If the CO2 reading is far too high it will start to blink red and produce an alarm sound.
The bright OLED Display shows the current PPM reading.
We use a high accuracy CO2 Sensor based on NDIR technology.
It includes all the parts needed to build your own frischluft.works device.
This kit includes:
- 1 High precision CO2 Sensor
- 1 Microcontroller Board with the Software already installed
- 1 OLED Display yellow/blue
- 1 Buzzer
- 1 RGB LED (10mm)
- 1 Resistor Array
- 1 Capacitor
- 1 Pushbutton
- 1 Power Plug
- 1 PCB
- 1 Enclosure
- 1 Lasercut Acrylic Cover
