GPS based Speedometer for Cars and Bicycles

In today’s fast-paced world, accurate speed measurement is crucial across various domains, from automotive vehicles to drones and athletic training. To meet this need, the following is a groundbreaking development: a GPS-based speedometer capable of measuring speeds up to 1854 kilometres per hour.

What sets this speedometer apart is its compact size, utilising the Quectel L86 GPS + GPS module and the IndusBoard with the 3D accelerometer and compass sensor, all packaged in a tiny 3cm IndusBoard coin form factor.

This makes it the smallest speedometer device, suitable for any automobile, bicycle, runner, athlete, speed bot, motor bot, drone, or robot, enabling real-time speed measurement. In addition, the device also provides IoT capability and connectivity to almost any Wi-Fi enabled device like a laptop, phone, or tablet to keep real-time track of speed and total distance covered.

The applications of this GPS-based speedometer are diverse and impactful. It can be used in automobiles to provide real-time speed feedback for drivers, enhancing safety and adherence to speed limits. It can be used in bicycles to help cyclists monitor their speed during training or recreational purposes. It is also beneficial for runners and athletes to provide precise speed measurements for performance tracking and training optimisation.

Moreover, it facilitates speed control and navigation accuracy in drones and robots, which is crucial for autonomous movement and obstacle avoidance.
