Thermopile : Construction, Working, Interface with Arduino & Its Applications
The thermocouple was first designed after the examination of the thermoelectric phenomenon in the year 1821 by Thomas Johann Seebeck. He observed a circuit that contains two wires made with two different metals like platinum or bismuth & antimony which are connected jointly at their ends. So heating one of the junctions will produce a weak electric signal that is simply proportional to the variation in temperature among the two welds. So this type of arrangement is known as a thermocouple. … [Read more...]
