/challenges-projects/project14/photonics/b/blog/posts/ir-break-beam-ifttt-sensorIf you are into home automation or just starting with home automation, then this is a simple project to undertake. Basically as part of this project I am putting together IR break Beam IFTTT node, which send a message to the IFTTT cloud based on whi.en-USTelligent Community 12https://community.element14.com/challenges-projects/project14/photonics/b/blog/posts/ir-break-beam-ifttt-sensorThu, 16 Apr 2020 09:54:32 GMT93d5dcb4-84c2-446f-b2cb-99731719e767:e9cf6902-8fc2-44e4-954d-283afee45753Fred271<p>Do you know if the beam break sensor modulates the IR it sends? That tends to make it far less susceptible to interference from sunlight, etc. I don&#39;t see it mentioned in the Adafruit documentation. It might be an interesting side bar to find out.</p><p>&nbsp;</p><p>You can probably tell I&#39;m looking at all the Photonics projects, as I&#39;ve just realised the next two projects I read would be useful to a) measure this and b) demonstrate that many IR LEDs sensors are modulated at 38kHz for this reason.</p><p><a class="jive-link-blog-small" href="/challenges-projects/project14/photonics/b/blog/posts/simple-light-flicker-meter">Simple light flicker meter</a> </p><p><a class="jive-link-blog-small" href="/challenges-projects/project14/photonics/b/blog/posts/photonics-wireless-communication-with-infrared">Photonics:&nbsp; Wireless Communication with Infrared</a> </p><img src="https://community.element14.com/aggbug?PostID=9035&AppID=254&AppType=Weblog&ContentType=0" width="1" height="1">https://community.element14.com/challenges-projects/project14/photonics/b/blog/posts/ir-break-beam-ifttt-sensorSat, 04 Apr 2020 23:17:21 GMT93d5dcb4-84c2-446f-b2cb-99731719e767:e9cf6902-8fc2-44e4-954d-283afee45753genebren0<p>Cool little project!&nbsp; Thanks for sharing.</p><img src="https://community.element14.com/aggbug?PostID=9035&AppID=254&AppType=Weblog&ContentType=0" width="1" height="1">
