TRACK YOUR RIDE You can leave your phone in your pocket or pack and still get all the data you want from your ride. With Auto Start enabled, all you have to do is start riding, and Trek Central will record all the metrics including distance, speed, elevation, power output, and more. You can also export your ride data to Strava or Komoot, and you can even share your rides to other Trek Central users. HOW FAR WILL YOU GO? See how far your Trek or Electra eBike will take you with real-time range calculations. Trek Central shows you how far you can go in each assist mode and will adjust accordingly as you adjust assist modes. You can even find your destination on the Range Cloud map to make sure you have enough battery to get there. Trek Central calculates range using advanced algorithms that factor in not only rider weight and battery capacity, but also topographic terrain data as well as historical rider behavior. DIAL IT IN Trek Central provides customized setup recommendations for your suspension settings and tire pressure. Select models like Fuel EXe 9.9 even incorporate Quarq TyreWiz and RockShox AirWiz sensors that let you know whether your pressure is high, low, or just right with a quick glance at Trek Central’s Ready to Ride screen. One-click connect pairs your sensors to your phone automatically when you connect to your bike. *Please note that the Trek Central app currently only works with Trek eBikes equipped with TQ or Hyena motors.

Pixel Size Calculator, calculate pixel size of camera sensor base on the megapixels input and common sensor format template. Features: • Input megapixel value and selects the input sensor size from preset. • Support custom sensor size. • Output sensor size in width, height and diagonal in millimeter. • Output x pixel value and y pixel value. • Output pixel size in millimeter. The formula to calculate diagonal from sensor width and height: Diagonal = √(w² + h²) where: w – sensor width. h – sensor height. Reference: 1 megapixel = 1000000 pixels 1 mm = 1000 µm Sensor width x Sensor height = X pixel value x Y pixel value Pixel size is the key factor in producing better quality images, the bigger the pixel size the better the image quality especially on noise reduction and low light capability. The image sensor format of a digital camera determines the angle of view of a particular lens when used with a particular camera. In particular, image sensors in digital SLR cameras tend to be smaller than the 24 mm × 36 mm image area of full-frame 35 mm cameras, and therefore lead to a narrower angle of view.
