1. GoSense Air Kit Contents and Unit Features
GoSense Air Unit Features
Main Enclosure – for protecting the internal electronics
Sensor Enclosure - for protecting sensors.
On/O Switch – turns the unit on and o. A USB cable will power the unit on when
connected to a PC even if the switch is o.
Power Indicator – Green LED light turns on when the unit is powered
Air Vents – Allows fresh air to contact the temperature/humidity sensor and assure
accurate readings
Light Sensitive Protective Window – a circular clear lens allows light to enter so UV
index values can be obtained
Micro SD Card/Slot – allows for data readings to be recorded and downloaded later
USB Port – allows for the user to connect to a PC (computer?) to change parameters
and observe live data readings
Record Button – This button is pressed to start recording and pressed again to stop
recording. A red LED will be visible during recording
Battery Compartment – Houses the two rechargeable AA batteries

2. GoSense Air System Performance Attributes
Run Time: up to 20 hours with 2000mAh batteries provided
Storage Capacity: 32GB with Micro SD card (number of samples stored varies with
sample rate)
Humidity Sensor: range: 20-80%, accuracy ±2% relative humidity
Temperature Sensor: range -40 to +257, accuracy ±0.36 degrees Fahrenheit
UV Sensor: peak spectral response between 300 and 350 nanometers (nm)
Gas Sensor: gas-sensitive element test concentration range: 10 to 1000 parts per
million (ppm)
Instructions in this User’s Guide assume the user is operating with a PC with USB ports as
well as an SD card reader and running Windows 10 with Microsoft Excel installed.
Arduino IDE is the recommended software for connecting to the GoSense Air unit for
configuration or observing live data readings.
A micro SD card will be used in the GoSense unit to record data and so the user may need an
adapter to be able to read the card with a PC.
The air quality sensor is intended for indoor use but may be used outdoors.
Verify that the Micro SD card is installed in the unit (see Appendix 3 - Installing and
Removing Micro SD Card).
Set the date, time, UTC oset, and location to match your location upon first time use of the
GoSense Air unit. (see Section 7 - Setting Date, Time, and UTC Oset and Section 8-
Setting Location for instructions)
Charge the AA batteries fully before each use.

GE N E R AL R E MI N DE R S B E F O R E USE DUR IN G USE
Before the first use, the air quality sensor needs to be powered on and in record mode for 48
hours by plugging it into a computer or powered USB. This is the “burn-in” period. This
does not have to be a continuous 48 hours, and the sensor can be used during this time.
Sensor use under battery power counts toward the burn-in period.
Power the unit and record for at least 30 minutes prior to each use to allow the gas sensor to
warm up and for readings to stabilize.
Do not insert or remove the Micro SD card while GoSense Air is powered. Turn the power
o and disconnect the USB cable when inserting or removing Micro SD Card. Failure to
follow this suggestion may lead to corrupt files or a damaged Micro SD Card.
Avoid blocking the air vent holes and the clear lens of the UV sensor to ensure accurate
readings.
Do not expose the GoSense Air unit to rain or water. Doing so will cause equipment
malfunction.
Do not expose the GoSense Air Unit to direct sunlight for extended periods of time to avoid
damage to the unit.
If the USB cable is utilized, the switch can be left o as power from the PC will be provided.
Power up the unit and record data for at least 30 minutes prior to each use to allow the gas
sensor to warm up and for readings to stabilize. Readings will stabilize after the sensor has
heated up for approximately 30 minutes.

4. Connecting GoSense Air to a Computer
Plug the small end of the USB cable into the GoSense unit in the slot marked “USB”
and the large end into the USB port of your computer. The cable has a USB A style
plug for the computer. If your computer has a dierent style USB port, an adapter
(not included) will be needed.
If you have administrative rights on your computer, you can allow access and
confirm any security or installation warnings.
If you do not have administrative rights, click the “Cancel” button on all Windows
Security Alert dialogs. The security dialogs may look dierent from the one shown.
