This document provides information regarding participation and use of See Sense ICON during data trials.
While collecting data, your phone will send one request per second to the server. Our tests show that given two lights collecting data over a 3 hour period, this would amount to approximately 60MB (or for one light, ~30MB) which is around 20MB per hour for two lights or 10MB for one.
If for example you are on a 1GB mobile data plan, collecting See Sense data for one hour at 20MB/hour equates to 2% of your 1GB data plan. Consider that it would take 50 hours of continuous See Sense data transmission to exhaust 1Gb of data!
NOTE: If you are using two lights, this will double the data usage.
The rate of smartphone battery power consumption depends on many factors. When using the See Sense app in a data trial capacity, the following functions need to be activated:
All three functions will require power from the battery which will likely be shared with other apps running on your mobile device.The following table shows the battery runtime for two lights running over a 5.5 hour period of continuous use on a typical journey while transmitting data. On a typical ride, your runtime will vary depending on flash rate, variant and type of light you are using.

Phone (Samsung Galaxy A3 2016) battery runtime is shown left for the same 5 hour period.
During this period, both ICONs are transmitting data continuously once per second over BLE to the phone, therefore the phone is also transmitting to the database over the mobile network.
Over a 5.5h period, the app demands 42% of battery resource over the measurement period.
NOTE: If using a single light, energy consumption will be halfed.
It is important that you use your lights in conjunction with the See Sense ICON app (download from App or Play Store). Check the following before you set off on a ride:
The light should now be transmitting data to the See Sense app on your mobile device over Bluetooth. The app then forwards the data to See Sense.
NOTE: You need to have a compatible Android or iOS smartphone that supports Bluetooth Smart (4.1 and above).
NOTE: See Sense ICON bike lights collect data only when they are either flashing or on constant mode and connected to the app.
Yes. If you previously purchased light or are considering purchasing another ICON while using a trial light, both lights will work together and will not interfere with the trial. You can connect both lights and the app will recognise them automatically. It is only the trial light that will collect data.
The light is measuring characteristics about the road conditions such as location and formation of potholes, situational information such as near-miss events, and also how often cyclists use roads, cycle lanes and greenways.
Yes. We will issue updates to the firmware and app on an on-going basis to improve user experience and add new features. When new firmware becomes available, the app will alert you automatically to download and install it.
We will share highlights of the data collected at feedback sessions for participants at regular intervals throughout the trial, as well as via a participant newsletter.
There are 3 entities involved in the Manchester data collection trial, they are:
Your data will not be shared with any other third party and is used solely for the purposes of the trial.
