We're selling off our stock of Thermopile Shields that we built for our KickStarter. They all work perfectly fine and we have good software support for them. However, they have a BOM of about $45 in quantities of 100 which means we have to spend $4500 building them in one go and then we have to sell them for about $100+ each to make ends meet which is too high of a price for most folks. If there's a lot of interest in the Thermopile Shield we can build more. Otherwise once we sell out no more will be built. However, we will continue to support any modules sold. We're selling the ones we have in stock at our manufacturing cost. When we bought the sensors they cost us $55 each versus the $40 or so they are at online now.

Anyway, if you buy one of our Thermopile Shields thanks for supporting us!

The Thermopile Shield gives your OpenMV Cam the ability to see heat. It features a 16x4 60°x16° field-of-view (FOV) sensor array capable of measuring object temperatures between -50˚C to 300˚C while measuring the room temperature (between -40˚C to 85˚C). Your OpenMV Cam's firmware has built-in support for controlling the Thermopile Shield using the fir module.


The Thermopile Shield is great for temperature measurement applications or security applications. For example, you can use the Thermopile Shield with your OpenMV Cam to detect the presence of heat which will allow you to detect if there is a person in the field-of-view. This makes the Thermopile Shield excellent for detecting people in pitch black.
