A Bike Rear Light with some more intelligence.
This might used in STEM education. Everybody can build their own bikelight and take it home and use it in every day life,
With a custom build bike light you can measure a lot of things:
- Jump Sensor with a Gyro, Acceleration Measurement
- Temperature, Humidity and Air Pressure Logging for height estimation and weather changes
- Bluetooth -> App Support to check you measurements during the ride
What is even more educational for Kids: They become more critical about privacy.
With a basic scan of your nearby WIFI Networks you can estimate your location.
This is nowadays quite easy with the Geolocation API that are offered by different companies. In this project I demonstrate a simple way to locate you bike with just the WIFI networks that are nearby. All needed is a simple ESP32 WIFI chip that scans on a regular basis the surrounding. Once three WIFI Networks have found the MAC Adress and the signal level is transmitted over Lora WAN Network.
The benefit of LORA WAN is: It is a long range network. So it may work in underground parking garages or indoor.
With this you can locate your bike even indoors (if Wifi is available)
Goal of this project is to make a dumb Bike light smart and add more features.
