Objective

Developing the speed measuring unit for any car project

Hardware

Sensor

1. Sharp 2D120X F 09

The Sharp distance measuring sensor is used to determine the speed/ velocity of the car unit. In this case, two identical sensors were used. According to the manufacturer SHARP, the range of the sensor is 4 cm to 30 cm, typical response time apprx. 39 ms, typical start up delay apprx. 44 ms, Average Current Consumption: 33 mA. The operating temperature is -10°C to 60°C, so that is ideal for this project as it is initially an indoor project. according to the stamp on the sensor, the manufacturing date was September 2016. According to the data sheet, the sensor should be mounted on any frame in such way that it gives the optimum result. For that the general instructions are available on the Data Sheet.

Current status of the Speed Tracker

It is not fully functional. Need to reset it before every time measuring speed. It is giving random result even if there is no testing. Probable cause: 1. Error in measurement algorithm 2. Error in source code 3. Faulty wiring 4. Defective sensor or other hardware parts

Display

Instead of using a led based display we can implement MQTT protocol to get the end result from the sensor in our smart phone with help of raspberry pi. That will allow to record the result more conveniently.
