Arduino/iOS – Bike speedometer tracking using bluetooth

Scope of the project,
add a speedometer on my MTB to store and track the trip using only Bluetooth transmission, send data to iPhone and store to cloud for later data-analysis.

Used components:

digital display (controlled by the iOS app). Can show current speed (km/h), total km, current temperature, current humidity.
GPS module
bluetooth module
DHT sensor for temperature and humidity
Swift backend
mongoDB as database
Swift iOS App
