Thermopile Sensor Schematic

Commercial thermocouples are inexpensive interchangeable.

Thermopile sensor schematic.

A thermopile is a device that converts thermal energy into electrical voltage. There are lots of cool applications they can be used for including motion sensors temperature probes fire alarms heat flow detectors robot sensors forge temperature monitors or low resolution thermal. It s what you find in those in ear infrared thermometers or remote temperature probes used in the food industry. The pins on the thermopile sensor a2tpmi are vulnerable and yes it may very well be a smart idea to connect a minimum of one of the unused pins to an isolated solder pad for mechanical steadiness.

This circuit is optimized for co 2 sensing but can also accurately measure the concentration of a large number of gases by using. Just about all parts in the diagram are as looked at from top meaning through the component angle of a pcb. A thin thermopile sensor called the heat flux microsensor hfm was described by hager et al. 1991 and is manufactured by vatell corp.

Vatell corporation 2002 because it is made with thin film sputtering techniques the entire sensor is less than 2 mm thick fig. A thermopile is an electronic device that converts thermal energy into electrical energy it is composed of several thermocouples connected usually in series or less commonly in parallel such a device works on the principle of the thermoelectric effect i e generating a voltage when its dissimilar metals thermocouples are exposed to a temperature difference.
