vAir Introduction

The "vAir - CO2 Monitor" is a device to monitor Indoor CO2 Levels.

Recent studies suggest that a high CO2 concentration is linked to reduced decision making skills, adverse health effects and bad sleep. On the other hand this may have or not have the same effects on everybody and the indoor air may be or not be contaminated.

Up to now - the price tag to validate such assumptions was quite high (> 100 Eur). All devices are quite geeky focusing on the raw numbers. Those were the two main factors that lead to the development of the "vAir" line of products, with it's only device as of now - the CO2 Monitor:

• Stay as cheap as possible, by sacrificing some gimmicks not really delivering value
• Design the device with simplicity in mind and yet add as much features as feasible

What has been done to keep the price low:

• Use cheaper CO2 Sensor with ~85% accuracy, compared to more expensive ones that offer 5% accuracy - We have decided that for the majority of users it is not important if their CO2 Levels are 2000 or 2300, if it is anyway around 2000
• Use 3D-Printed enclosure instead of industrial-grade plastic box
• Instead of nice software - spend the resources on using existing services for data logging and display, and do configuration by connecting the device via USB Port
• Don't use fancy carton boxes which are anyway thrown away, but cost money to print and design

Features:

• CO2 detection in the range 400-3000ppm (>85% accuracy)
• Values are displayed with 6 Leds
• Auto-dim feature for the leds based on ambient light
• (Optional) OLED Display to show current CO2 Value or a graph with the history for the last 12 hours
• (Optional) Wifi Connection - data can be logged to thingspeak.com and other providers, and monitored via their tools
• Configuration of the device via the USB Cable
• (Optional) 1000 mAh Battery (which allows for 10 hours of autonomous work)
• Power via Micro USB cable and USB power adapter (~100 mAh consumption)
