Constructing Smallest GPS based mostly Speedometer with IoT Capabilty

In in the present day’s fast-paced world, correct pace measurement is essential throughout varied domains, from automotive autos to drones and athletic coaching. To fulfill this want, the next is a groundbreaking improvement: a GPS-based speedometer able to measuring speeds as much as 1854 kilometres per hour.

What units this speedometer aside is its compact dimension, 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 type issue.

This makes it the smallest speedometer system, appropriate for any vehicle, bicycle, runner, athlete, pace bot, motor bot, drone, or robotic, enabling real-time pace measurement. As well as, the system additionally offers IoT functionality and connectivity to nearly any Wi-Fi enabled system like a laptop computer, cellphone, or pill to maintain real-time observe of pace and whole distance lined.

The functions of this GPS-based speedometer are numerous and impactful. It may be utilized in cars to offer real-time pace suggestions for drivers, enhancing security and adherence to hurry limits. It may be utilized in bicycles to assist cyclists monitor their pace throughout coaching or leisure functions. It is usually helpful for runners and athletes to offer exact pace measurements for efficiency monitoring and coaching optimisation.

Furthermore, it facilitates pace management and navigation accuracy in drones and robots, which is essential for autonomous motion and impediment avoidance.

Moreover, it optimises efficiency in pace bots and motor bots by monitoring pace in varied robotic functions.

Fig. 1 exhibits the prototype fitted on a bicycle. For making this GPS speedometer for the bicycle, the parts required are proven in Invoice of Supplies desk.

Programming GPS-based Speedometer

For coding, first, it’s mandatory to put in the TFT espi and TINY GPS Plus libraries; the subsequent steps are defined within the code. Fig. 2 exhibits a snippet of the supply code.

Circuit and Working

Fig. 3 exhibits the circuit diagram of the GPS speedometer for bicycles and vehicles. It’s constructed across the IndusBoard, capacitance touchchip CST816, GC9A01A spherical show, and L86 GPS module.

The L86 GPS makes use of the serial port with a baud charge of 9600 to ship the GPS knowledge. The IndusBoard helps each software program and {hardware}. The L86 GPS pins RXD1 and TXD1 are linked to TX and RX1 of the IndusBoard, respectively. In response to the L86 GPS module dataset, the module will be powered from a variety of two.8V to 4V whereas consuming round 100mA in working mode.

The IndusBoard has 4 output pins that may deal with the present and energy. Due to this fact, the three.3V and GND pins of the IndusBoard are used for the GPS powering. For extra particulars in regards to the GPS powering system, discuss with the earlier month’s difficulty of EFY or use its datasheet.

Building and Testing

For the development of the system, solder all of the parts in response to the circuit diagram (see Fig. 2). After soldering the parts collectively, repair them on high of the bicycle deal with or automotive’s dashboard. Now, energy the system and and begin driving.

Based mostly on the change in GPS location with time, it would begin giving the pace, which will be seen on the system, as proven in Fig. 4.
