Quick Start
What is Sensor Node?​
Unboxing​
Thank you for choosing Sensor Node. We really hope you will be delighted with your air quality sensor, and that it will help you to look after for the well-being of your families, classmates or your business.
Inside your Sensor Node air quality sensor, you will find
User Guide​
To save on paper we've printed the user guide on a tiny business card. On one side we've put QR codes to download the mobile app and go to date online documentation. We will do our best to keep these up to date.

On the flip side, we've put an at-a-glance guide to thermal comfort and ventilation. It's good to know what we're aiming for after all. It might be good to stick this next to your monitor. Especially until you've got a feel for the readings.

Insert Batteries​
If you have purchased either of the smaller battery powered Sensor Nodes, you'll need to insert the batteries. The smaller LP WAN device takes 2 x AAA alkaline batteries, while the larger WiFi device takes 2 x AA batteries. In both cases, the batteries should last for several years. The plastic enclosure will pop apart quite easily without using any tools. It's important to use good quality batteries. We recommend Varta High Energy or Long Life (they have a 3000 mAHrs capacity) which you can find in Bunnings for a good price. Good batteries will extend the operating lifetime by up to 3 times against standard cheap batteries.

Installation​
Placement​
Sensor Node should be attached to an interior wall away from windows or drafts, or on a bookshelf or similar. Be careful not to place it in direct sunlight as this will affect the readings. For best accuracy, it should be placed between 1.2 m and 1.8 m above floor level. Make sure the air slots and sensors are not obstructed.

Carbon Dioxide and Other Variants​
If you have purchased a CO2 Sensor, Particulate Matter Sensor or one of the other product variants, these are attached to the wall with 2 standard screws, placed in a vertical line 35 mm apart. Before putting the sensor in place, loosen the anti-tamper bolt on the bottom and ensure that the USB cable is connected. Locate the sensor onto the screws and lower it into place. Tighten the anti-tamper bolt again. The unit is now securely attached to the wall, and the USB cable cannot be removed at the device end.

PRO TIP
Use the QR code on the quick start guide to download the app
Register An Account​
In the app, you will be prompted to provide a user name, email address and a password. If you forget your password, no worries, just use the "I forgot" link in the login page to reset it.
Add/Scan New Device​
Once you've signed into your account, you can register your first sensor node device. First click on "Add/Scan Device" from the Home page in the mobile app. A QR code scanner will appear. There will be a QR code on the sensor node device, and on the box it came in. This contains unique credentials are used to register the device to your accout. Once you have scanned the QR code, follow the remaining steps in the add new device wizard. If everything goes well, at the last step, the sensor node mobile app will ask if you want to connect to Wi-Fi next.
Connect to Wi-Fi​
WiFi Connection Wizard​
After you have successfully registered your device, click "Configure WiFi" to link you device to your network. Before you proceed, push and hold down the mode button on the back of the sensor node device. After about 3 seconds, the device will restart. Once you see the Bluetooth Symbol appear, the device is ready to connect securely via Bluetooth with your phone. Back in the mobile app, click "Configure Wi-Fi". If you experience any problems during this phase, just press (and hold for 3 seconds) the sensor node mode button again to set up a fresh Bluetooth session and try again.
PRO TIP
If this process succeeds, you will see the "Success" page in the app. However, occassionally the communications between the device and yuor phone can complete early. In that case, check if the little WiFi icon is present on the device to confirm that the process has worked.
Changing / Updating your WiFi Connection​
If you need to repeat this process in the future, or move to a new WiFi network - no problem. In the home page of the mobile app, click on the device. At the bottom of the device page there is a WiFi button. Click this to go through the WiFi Connection Wizard again.
Sensor Node Web Portal​
In addition to the mobile app, Monkeytronics also provides a full featured Web portal. This was designed to enable organisations with a large number of devices to manage their fleet of devices and quickly filter and report on them to get maximum value from their data.
The web portal is available as a complete stand alone alternative to the mobile app. However, in order to add new devices to your account, you do need to use the mobile app. This is because we use QR code scanning to register the device's Porting Authorisation Code (PAC), and we also need to communicate directly with the device over Bluetooth LE as part of the WiFi provisioning process.
