Final Year Project (Heat Sensor)

It is a sensor that provides information to the gas valve on your gas water heater. It tells the gas valve when and if it should release gas. It also tells it how much gas to release.

Figure 1 shows basic block diagram of Temperature sensor based rate responsive pacemaker. The first block defines the temperature sensor which converts the physiological variable in to an electrical signal. Which then taken in to account and work as input to analog to digital converter that convert analog signal (Temperature) into its equivalent digital

Thermoelectric cooling uses the Peltier effect to create a heat flux between the junctions of two different types of materials. A Peltier cooler, heater, or thermoelectric heat pump is a solid-state active heat pump which transfers heat from one side of the device to the other, with consumption of electrical energy, depending on the direction of the current. Such an instrument is also called a Peltier device, Peltier heat pump, solid state refrigerator, or thermoelectric cooler (TEC). It can be used either for heating or for cooling, although in practice the main application is cooling. It can also be used as a temperature controller that either heats or cools.

For heat pumps producing warm air the temperature should not drop below 38°C to prevent risk of

This project was performed as part of my Master of Electronics and Computer Engineering/Master of Electronics and Energy Engineering dissertation from Griffith University, School of Engineering, Australia. For this project I worked under the direct supervision of Prof. David Thiel, who was a source of immense help and motivation through the course of this entire project. In my project I also encountered problems with surface modelling in which I sought invaluable assistance from Dr. Hugo Espinosa.

* Its aim is to perform as an energy-dissipating device to reduce energy level of water flows.

So when the wires have been put into the correct order, you can trim the wires and then insert the wires into the clip. You would then use the tool to clamp the wires into position so they do not fall out of the clip.

In Exp # 1, the voltage was continuously changing until the heater temperature (T10) reach the steady state condition and at this time, T10 was recorded to get Qr and Qc. In Exp # 2, the voltage was kept constant while the air velocity was changing continuously and T10 was recorded at the state condition to determine Qf and Qr. In Exp # 3, the angular position and air velocity were changing continuously and T10 was recorded at the state condition. The error percentage in Experiment #1 between Qc experimental and Qc theoretical ranges is between 0.95% and 10.7% while the error in Qr experimental and Qr theoretical ranges from 7.9% to 21.5%. Finally, the error percentage in Experiment #2 between Qtot theoretical and Qtot experimental ranges from 5.6% to 6.22%, while the error in Qt theoretical and Qin ranges from 50.5% to 80.5%.

If you are looking for solutions for heating inside your home, you need to first understand the basic differences between a boiler and a furnace. If you have no idea about what we are talking about, do not worry at all. It is completely normal to not have proper understanding of such technical terminology. It is why Levine Heating is there to take care of all your worries.

Thermal conductivity heat is transferred as a consequence of temperature difference between 2 bodies, heat energy passes form a hotter to the colder body. Specific heat capacity is the amount of heat energy required in joules to raise 1kg of a substance by 1 degree Celsius, different substances absorb heat energy at different rates not all substances require the same amount of heat energy to increase the internal temperature of a substance this depends on the mass and the material it’s self. To demonstrate specific heat capacity of a solid an experiment was carried out using 1kg aluminium mass and 1kg copper mass heat was conducted to the masses by

The circuit is power up by 9V to 12V input and voltage regulator reduces the input voltage to 5V. LM voltage regulator is operating the microcontroller circuit, LCD display, DTMF circuit and the L298N motor driver. The green LED indicates that the power supply circuit is functioning and working perfectly.

The aim of this paper is to design a wireless sensor node using FPGA for fire monitoring and control. FPGA is used in the wireless sensor node design in order to enhance the processing capabilities of the system to meet the target applications. The sensor nodes in a wireless sensor network are normally microcontroller based which are having inadequate computational capacity related to various applications. This paper describes the selection, specification and comprehension of a wireless sensor node using the field programmable gate array (FPGA) based architecture for an early detection of hazards (e.g. smoke and fire). The FPGAs in its place are more proficient for complex computations in compare to microcontrollers. Another benefit of using FPGA is also due to its reconfigurable characteristic without changing the hardware itself. The node is implemented using Spartan 3A FPGA board from Xilinx. A design of simple hardware circuit with different type of fire sensors enables every user to use this wireless fire security system. The FPGA will constantly supervise all the sensors and if it senses any security trouble then the FPGA will send the information to the PC central monitoring station wirelessly using Zigbee technology. The system is based on the Lab VIEW software.

At the circuit this time, it connects the output of the detection circuit with the negative input of the signal detector and it makes the voltage of the positive input constant.

The sensors need 2 voltages, heater voltage (VH) and the test voltage (VC). VH used to supply certified working temperature to the sensor, while VC used to detect (VRL) on load resistance (RL) which is connect inseries with sensor. In order to make sensor at the better performance, suitable RL value is needed.
