The temperature variations achieved using our
prototype is of the order of 20-550 C. The DC power
source to the Peltier element is a solar cell panel. The
prototype can be modified according to specific
requirements by changing the Peltier element by a
series-parallel combination (Thermopile Peltier
element) to achieve greater degree of temperature
variations. Further, the prototype can be made a
intelligent system by incorporating signal processing
and signal conditioning elements.
