Fig 3: Flowchart for parking space availability III. AUTOMATIC CAR PARKING SYSTEM This has been implemented on microcontroller. This core task is divided into two procedures. The first duty is to press the push-parking button on the touch panel, which is already in built in the steering wheel. Now, the microcontroller will calculate the distance travelled by the vehicle from WPT and converts the distance. The work of the driver is to choose the available parking…

field. Soil conductivity depends on the moisture content around the probes. This is particularly useful for monitoring moisture levels around roots of crops planted in an organized manner. The network architecture allows real time monitoring. A microcontroller is used to scan the array of sensors for output values by operating a switch IC, to calculate the moisture percentage value corresponding to the voltage output of each sensor, to display the percentage moisture value or to operate the…

NET Framework. In that time, I created a collection of small personal applications and games as I experimented with code and concepts. At age 17, I became interested in interacting with the physical world through the digital one with the use of microcontrollers. With the Internet and a copious amount of trial-and-error, I taught myself a functional understanding of electrical engineering. I completed several smaller projects, such as controllers for lights, motors, and servos, to gain experience…

The HC-05 is a serial Bluetooth module for transparent wireless serial communication. It communicates with the microcontroller using serial port [5]. It operates in the 2.4 – 2.485 GHz frequency band The HC-05 has 6 Pins. Table 3.1 Pin description of HC06 Pin Description Key to toggle between data mode and command mode, if set to high, it works as command mode, but default is data mode. RXD Receive data serially (received data will be transmitted wirelessly by Bluetooth module). TXD Transmit…

CHAPTER 1 INTRODUCTION 1.1 Project Background Recent developments in new technology advances are from fruits of labor as a product of intensive research designed to make an important contribution to the care of older and aged people, both in institutions for elderlies and at our home [1]. Various type of electronic sensors, video health monitoring, remote health monitoring and equipment such as body fall detectors, door security monitors, bed alerts, pressure sensitive mats and smoke and…

Design and implementation of an Electronic system for identification of rebars in reinforced concrete. Abstract- In this paper non-destructive method is implemented in which magnetic self-designed sensor is used to detect position of rebar in reinforced concrete. During the renovation of old buildings it is necessary to locate rebar accurately to avoid damages in construction. This is achieved by Magnetic sensor which is made up of E-shaped core also primary and secondary windings. Due to…

IV. EXPERIMENTAL RESULTS We validated the effectiveness and the advantages of our proposed design by testing both hardware and software. We have divided the validation process in two steps: 1) validating the Microcontroller based dispensing unit and 2) Tracking patient’s adherence to the prescribed medication from the server in two ways a) tracking by central nursing stuff when used within hospital b) tracking by patient’s care taker when used within house. The reason for choosing LPC2148 is…

8. Overview of the Arduino Sketch 8.1 General Codes MediaTek labs states that an Arduino sketch “is a source code file representing the core controlling logic for the LinkIt ONE development board. It consists of two main structures: setup and loop” (MediaTek Labs, n.d.). In this section I will discuss what the above code do. First, LinkIt ONE initializes the Ubidots account, then the sensors, Wi-Fi or GPRS, the location and finally the serial port. To minimize battery consumption, I did not use…

One of the parameters that determines water quality is pH. It is defined as the negative logarithm of the hydrogen ion and is intended to be a measurement of the balance of acids and bases. Temperature affects pH. In pure water, a decrease in pH of 0.45 occurs when temperature is increased by 25°C [11]. There are several methods for measuring pH. The most common is the use of a glass electrode sensible to it, a reference electrode and a measurement device. Another method is the use of…

transmission inside the multi-wire tether act as conductors to give the electrical power to the ROV and its electrical components. ii. Signal wires: Smaller signal wires on ROVs conduct signals which govern the polarity of power to the motors by ROV microcontroller and other components. On our ROVs, the 12V DC power is used to turn on or off the motors by double pole / double throw (DPDT) switches on the surface and this 12 VDC is also used to give power to the modules and sensors. iii. Clear…
