The sensor is hand-soldered onto a custom made PCB in the STEMMA QT form factor, making them easy to interface with. That said, for general environmental sensors, it will give you a good idea of trends and comparison. But it's important to keep that CO2 balanced - you don't want too much around, not good for humans and not good for our planet. International Orders - the following rates are for New Zealand and will vary for other countries: If you order lots of gear, the postage amount will increase based on the weight of your order. Adafruit have of course broken out all the pins to standard headers and added a 3.3V voltage regulator and level shifting so allow you to use it with either 3.3V or 5V systems such as the Raspberry Pi, or Metro M4, or Arduino Uno. Mmm isn't it wonderful? The success of this project made me want to create a smaller, more subtle version that I could carry with me to meetings. For advanced hackers, they can cut/solder the backtraces to change whether the regulator is enabled and what I2C logic level is desired. Products that weigh more than 0.5 KG may cost more than what's shown (for example, test equipment, machines, >500mL liquids, etc). Detect a wide range of Volatile Organic Compounds (VOCs) and H2 and is intended for indoor air quality monitoring. Another nice element to this sensor is the ability to set humidity compensation for better accuracy. Mmm isn't it wonderful? If you have any questions then feel free to contact us.
