MULTI-ULTRASONIC SENSOR SYSTEM - SERIAL COMMUNICATION

SUMMARY

As the MSP432 runs the ultrasonic sensor begins to check if any object is in range of its sensors. Once an object is 2 to 400 centimeters in range of the sensor it begins to measure the distance of the object in units of centimeters. Each MSP432 board transmits the distance of their corresponding ultrasonic sensor to the adjacent board, which then receives and outputs that given distance onto its serial monitor.

ULTRASONIC SONAR RADIO COMMUNICATION

SUMMARY

As the MSP432 is running the ultrasonic distance sensor begins to check if any object is in range of its sensors. Once an object is 2 to 400 centimeters in range of the sensor it begins to pick up the signal. When one person enters a “T” on their serial monitor and sends it the ultrasonic distance sensors signal from that person’s board is then sent to the serial monitor of any MSP432 board that is in wireless distance of the NRF2401+ 2.4GHz wireless RF transceiver module. Once sent to the other person the module picks up the signal with the distance and displays the measured distance of the object from the other persons MSP432 onto their serial monitor.

SENIOR DESIGN PROJECT - IR ROOM TEMPERATURE MONITOR

SUMMARY

Using the Raspberry Pi as the main microcontroller, in conjunction with two Arduino Uno’s, this project proposes a method to set an accurate and efficient, energy-saving solution to control the temperature of a room. By acquiring the parameters of temperature inside and outside of the room with sensors we can get a series of appropriate control signals to control the heater ensuring a comfortable temperature is kept within the room. This proposed system of ours can greatly reduce energy consumption and ensure real-time monitoring of the room while giving the end-user the required room temperature he or she needs.

DATA LOGGING

Two microcontrollers pick up the temperature in the room from its two opposing sides and then send the averaged temperature to the third microcontroller, which will then begin to change the temperature of the room by controlling the heater using Pulse Width Modulation (PWM) modulation to vary the average power delivered to the device. A PID control voltage will be used to set Pulse Width Modulation.
