    Questions on the Air Quality Egg
    Hi, sorry for the delay in responding, this is an unusual place for us to receive inquiries. In the future, please feel free to email support@wickeddevice.com directly.

    The data can be downloaded using the OpenSensors.io APIs, e.g. using a Python script or similar. I've been working on fleshing out this capability recently, and would be happy to work with you to see if what I'm doing meets your needs or if we can make it friendlier.

    The sampling, averaging, and reporting intervals are runtime configurable using a terminal with the Egg in config mode. The default settings are 5 second sampling and reporting intervals, and 160 second averaging interval (moving average). With the right settings you can disable averaging (i.e. sampling interval equal to averaging interval).

    The Egg is environmentally resistant, but not truly water proof. It is intended for outdoor use in general though. We typically recommend that the Egg be kept out of direct sunlight and that it be sheltered from the rain (e.g. under the eaves of a house)

    The sensors used on the Egg are capable of measuring 0 to 20ppm for NO2, and 0 to 1000ppm for CO. Much larger ranges than what would typically be found in nature.

    Questions on the Air Quality Egg
    Hi, I'm hoping to do two experiments with the AirQuality Egg, and I have a few questions regarding the device:

    How can data be downloaded? (specifically we are looking for time point data with associated measurements in a flat file)

    What is the sampling frequency of measurement in the egg? Is data reported as a single point measurement or integration/average/median/etc of a set of values collected over a time interval?

    If the egg is used to collect outdoor data, are there problems associated with rain/dust/etc?

    What range of CO and NO2 concentrations can the egg measure accurately?

    Wish List for sensors
    Programmable light wavelength. .....
    To measure dust and have digital display , how about consider laser dust sensor , with much better accuracy
