In this paper, we will discuss how we built, programmed and designed a system to monitor the temperature of a person's home to make sure that if the temperature of the house falls below a threshold, a notification will be sent to a smart phone, tablet or PC to warn the person of the situation. An additional notification will be sent to let the person know that the house is back above the threshold...
Renewable energy exploitation becomes more and more important as consumption type energies are being exhausted. This paper presents the utilization of photovoltaic power applied in LED street lighting and an intelligent street lighting system is developed. The system consists of photovoltaic panels (12V, 60W), a lithium iron phosphate battery(12V, 40Ah), a LED array, a photovoltaic charge controller(CN3722),...
Disasters create mass casualties and the number of casualties usually surpasses the capability of medical resources, hence, medical teams must attach paper triage to casualties for determining the priority of treatments based on the severity of their condition. However, since casualties' condition could change at anytime, the paper triage cannot provide the latest information of their health condition...
The development of a microcontroller-based system design course using the PSoC Lab Manual and customly designed project assignments are presented in this paper. Due to the natural segregation of computing blocks on these devices as digital vs. analog blocks, microcontroller-based systems can be taught in 2 terms, for digital and analog systems design separately. The presented course is designed to...
A novel temperature sensor suitable for continuous monitoring of the health of a solar photovoltaic (PV) panel that powers an earth bound satellite is presented in this work. The method proposed here employs one of the photovoltaic cells of the panel itself as the sensor for measuring the solar panel's temperature. In order to make the sensor work even when the panel is not receiving sunlight, that...
In this paper, a device is developed and designed to measure CO2 concentration in fuel cell system for evaluating the generating power efficiency and the environmental quality. Also, it can be used to measure the temperature and humidity of the generating system at the same time. For the device, MSP430 based design scheme is presented to measure the signals from CO2 sensor, temperature sensor and...
This paper depicts the implementation of a colorful RGB-LED light source with an 8-bit microcontroller. The microcontroller regulates LED light output with pulse-width modulation current and changes the light color with the current ratios of red, green and blue LEDs. While the LED light output varies with temperature, the microcontroller stabilizes the light output of LED with feed-forward compensation...
One of problems of the most common used industrial controllers is in their very expensive price. Moreover, they not offer any other features except some basic ones, how to affect controlling process (e.g. settings of PWM (Pulse Wide Modulation) switching frequency). On the other side, developing of a new analog controller to control a simple system is not reasonable due to financial or time issues...
Most systems are controlling by common PID controllers. These PID controllers are available in variety possibilities. They are divided by types of controlling systems, by speed of action interference, by complexity, by robustness etc. Most of industrial controllers are very expensive and except of some basic setting they are not offering any other way, how to involve into controlling process. On the...
