Title of Activity:

Project Progress.

ü  Testing the Thermoelectric Module (Pelteir)

Objective:

- For make sure this Thermoelectric Module are functioned.

- Measure the output value from the Thermoelectric Module.

- Determine the maximum performance using this Thermoelectric Module.

Content/Procedure:

- For make sure this Thermoelectric Module are functioned, using the power supply to testing this Thermoelectric Module.

- Measure the voltage and current output produced from the Thermoelectric Module using Multimeter.

- To produce the max output, try to give the different temperature on each side of the Thermoelectric Module.

Using the ice and human body temperature as a different input value of the temperature

Result and Analysis:

As a result, for make sure the Thermoelectric Module is functioned;

ü  The batteries have been used as a power supply.

ü  And the Peltier will produce the different temperature each side of that module (Seebeck effect).

ü  When the value of the power supply is high, the different of each side temperature also high.

And for measuring the output value produced from the Peltier, the ice have been used to get the 0^o Celsius temperature. And the other temperature that have been used is the human body temperature, 37^o Celsius. As a result, the output value reading that produced from that 2 different temperature on the Peltier have gain some voltage value, based on Seebeck Effect. So, to measure that output the multimeter have been set to 2V to measure the voltage gained from the Peltier. And the voltage that produced are around 500mV~600mV.

Lastly, based on the experiments the output value can be produce more, when the different of each side temperature are also high. The temperature of human body can be replaced with the other temperature that are more heat. As an improvement to gain more output value, it could be to using some heated object that can give more high temperature.

 Output voltage is 517mV

Output voltage is 588mV

Output voltage is 696mV

Conclusions:

           As a conclusion, the Thermoelectric Module can be operating when we supply the power and there will give some different temperature of the each side of that module. And this Thermoelectric Module can produce a small output value, and this part will combine with the other part for make sure all combined parts will give a high output value.
