Many of you have already checked the energyAware Profiler application from Simplicity Studio and know how to use it, but it is also possible to monitor the power consuen-USTelligent Community 12https://community.element14.com/challenges-projects/design-challenges/energy-harvesting/b/blog/posts/carbon-monoxide-detector-power-consumptionThu, 25 Apr 2013 21:28:51 GMT93d5dcb4-84c2-446f-b2cb-99731719e767:19da3d8a-03f3-425f-b581-906246888545vsluiter1<p>Hello Wojciech,</p><p>&nbsp;</p><p>Have you also looked at getting using the &#39;4 to 20mA&#39; converter (LTC3105)? I&#39;ve been trying it out for harvesting energy out of motion, and it works at a very low starting voltage. The datasheet also describes circuits with Peltier elements.</p><p>For these reasons I think the board is indeed more a demo board than a development board; it would be nice to be able to swap the sources around, and have some jumpers to solder resistors to. Although you can see now how small the circuits can be, it is a bit daunting to patch the circuits.</p><p>&nbsp;</p><p>Good post by the way on using the development kit as a current measurement tool; hadn&#39;t thougt of that yet.</p><img src="https://community.element14.com/aggbug?PostID=15694&AppID=106&AppType=Weblog&ContentType=0" width="1" height="1">
