Question 1

What kind of sensors are they?

Accepted Answer

The sensors are part of our service that we offer our customers with our innovative plant concept. These are sensors that measure air quality.

Question 2

What is the purpose of installing such a sensor?

Accepted Answer

Air quality has a significant impact on employee health and sickness absence.
We have developed our own air quality dashboard, and sensor technology is used to measure nine individual data points that comprehensively represent the air quality in office spaces. Through the various analyses (virus risk, etc.), it is possible to accurately understand and track the impact of air on employees. As a result, fact-based decisions can be made.

Question 3

Which data exactly are or could be collected from us? The homepage talks about "Sound", "Light" and "Virus Index", for example.

Accepted Answer

The sensor measures the following values: CO2, fine dust, NO2, humidity, air pressure, CO, temperature, O3, TVOC.

Through additional sensors we can also measure light and noise.
The software then analyzes these values and provides insights into different topics such as virus risk, comfort, dermatological health, room occupancy, etc.

Question 4

What kind of data is transmitted exactly (air quality data, location, GPS, noise etc.)?

Accepted Answer

Only the data of the parameters (sensors) of the device is transmitted.

Question 5

Do we get access to the sensor data?

Accepted Answer

You get access to our dashboard, where you can access all raw data and the further analyses at any time.

Question 6

Who has access to the data?

Accepted Answer

Only you and us. uHoo, our partner, only has access to the raw readings and if needed they can be anonymized so that uHoo cannot attribute this data to you.

Question 7

Where is the data stored and processed (geographically)?

Accepted Answer

The data is stored on Amazon (AWS) servers in Frankfurt. In addition, our partner uHoo stores the data within the EU. This way we are GDPR compliant.

Question 8

How many devices will you install?

Accepted Answer

The number of sensors depends on the size of your office.

Question 9

What are the specifications of the sensor?

Accepted Answer

Height: 165 mm / 6.5 inches, Dimension: 85 mm / 3.4 inches diameter, Weight: 265 grams / 0.58 lbs. WIFI: 802.11 b/g/n @ 2.4 GHz. Security: AES 128-bit encryption: Power: Micro USB power adapter.

Question 10

Does the sensor need constant electricity?

Accepted Answer

Yes, the sensor needs to be plugged into the electricity continuously.

Question 11

Can the sensor be connected to the LAN?

Accepted Answer

No, the sensors do not have an ethernet RJ45 port. They only support WIFI 802.11 b/g/n @ 2.4GHz (dedicated 5GHz Wi-Fi network not supported)

Question 12

Our SSID will change the password every 90 days/6 months, will it still work?

Accepted Answer

No, unfortunately not. Each time the password is changed, we will need to re-install the sensors.

Question 13

Do you set an IP address on these devices? Can this be done statically?

Accepted Answer

The sensor does not have an option to statically assign an IP address. It takes it from the DHCP server. You may assign a fixed IP on the DHCP server for the MAC address of the sensor and then use that IP address in the firewall.

Question 14

Why do we have to open the described ports?

Accepted Answer

These ports need to be open, so that the sensor can access the server.The device checks for regular firmware updates and downloads them, and it sends the air quality data in a regular interval. However, there is no inward connection opening request towards the sensor.

Question 15

Regarding the ports, is proxying of ports 80 and 443 acceptable for the sensor operation?

Accepted Answer

The sensor does not support authentication through proxy, but if the sensor can access the 5 websites and the ports, and can upload and download data, then it should be fine. There is no option to administer a proxy server on the sensor.

Question 16

Is it OK that the sensors are responding to ping relatively not well?

Accepted Answer

That scenario is normal. The device will only respond to ping when it's connected to the network. However, since the device is not consistently connected to the network (power saving feature of the device), the ping will show a high failure rate.

Question 17

How are the sensors calibrated?

Accepted Answer

After the first time set up, please keep your uHoo device running for 48 hours continuously. During the first time, the readings will be fluctuating to learn about your environment and calibrate. Your actual readings will only be available after 48 hours. Prior to that, the readings are based on what the device is learning about your indoor environment.

Your uHoo also has an auto calibration technology. This technology was developed to ensure the long term performance of the sensors. Auto-calibration happens every 168 hours of continuous use. The CO2 sensor would need at most 3 cycles of auto calibration to achieve full accuracy. Whenever the device is switched off then switched back on, the VOC, nitrogen dioxide and ozone sensors will only start sensing your air after 30 minutes. During the first 30 minutes, they will remain at very low levels.
