Question: Discuss about the Electronics Engineering Report. Answer: Introduction Sensors are capable of detecting the three-dimensional motion that has been available commercially for many decades and has been used in ships, aircraft and automobiles. However, its price, power consumption and size have saved it from the massive adoption of electronics products (Guna et al., 2014). Moreover, there are other motions sensing, or detection technologies are commercially available. Choosing the right sensor is not a complicated process. We can define the sensor to be a simple device that measures a physical quantity such as pressure or speed and then transmit it to an electrical signal that can be measured. Sensor that is Best for Detecting a Fast Moving Rope There is particular procedure to choice the right sensor such as Accuracy, Resolution, and Type of sensor and Range. There are various types of classified sensors such as Flow Sensor, Humidity Sensor, Proximity sensor, Position sensor, Pressure Sensors, Temperature, Heat or Thermal sensors, etc (Fan et al., 2012). Among all this primary and principal types of motion sensor the right choice for this project is Ultrasonic sensor. The primary object or purpose of the Proximity sensor such as an ultrasonic sensor is to produce high-frequency sonic waves and obtain the reflected resonate or echo by the target. It is best to detect the fast rotating object in this case rope the best sensor we can consider is Ultrasonic sensor. Figure1: Ultrasonic Sensor (Source: Li et al., 2013, pp-1094) The Ultrasonic sensors are such application devices that are used for transformation of electrical to mechanical energy to calculate the distance from the target object to the sensor (Yamada et al., 2016). Ultrasonic sensors have multiple features such as they can not only measure the distance but they can also detect the objects, can sense the position of the object, etc. In this case of an experiment, we are looking for such sensor that can detect the object position and generate some electrical signals that can help in rotating the jumping rope automatically. The idea is to sense the movement of the string once and generate the rotation of the rope till it's is stopped. Reasons to Included Proximity Sensor (Ultrasonic Sensor) The Ultrasonic sensor works on the principle of sound waves. The primary objective of this sensor is to detect the object without any physical contact while the detection is done. A particular kind of sonic transducer has been used for the ultrasonic sensor that allows alternative reception and transmission of the sound wave (Lynnworth, 2013). The sound or sonic wave is reflected by the transducer and received back in the transducer. There are some positive points that we need to look why we are considering the Ultrasonic sensor. The output of the ultrasonic sensor is linear between the target and the sensor. The detection is accurate even if it is a tiny object. It can perform the best in critical conditions. They are designed in such a way that for detecting the object without any contact. It is easy to implement it in custom designs because they are available in cylinder and cube forms (Donovan et al., 2013). But there are some drawbacks as well that need to be addressed. The environmental changes can affect the response of the sensor such as temperature, pressure and humidity. It has a minimum sensing distance that needs to be considered when we choose the sensor. It needs to be viewed in a high-density surface rather than using a low-density surface because they can absorb the sound waves that are produced by the sensor. This sensor can be used in ultrasonic motion detector for detecting the motion or movement of the object in a limited or small space. It is the most cost-effective solution that can be used for the present project. The transmit sensor will use to produce alarm or signal in that section and when the transmit alarm or signal will be block by any moving component, then the signal receiver would obtain the signal and then it will strengthen the signal using the transistor. Generated signal can be transmitted to a connected motor which will help the electrical signals to be converted into mechanical energy and rotate the shaft of the motor that will assist in turning the rope automatically. Conclusion A general concept of involving a sensor that can detect a single motion of the object and keep looping the same rope multiple times till the system is stopped. So the research idea is presented that the Ultrasonic sensor will be installed, and when the sonic wave is blocked by any object movement then it will send the electrical signal and convert it to mechanical energy, and then the whole principle of automation is done.
