I'm working on a prototype that will receive 14 Hz IR signal. I'm a bit stuck on finding the proper hardware. I see a lot of 38KHz but nothing in the 14 Hz range. Any ideas or help here. Thanks.
You can use the ADPD1080 as your analog front end. https://www.analog.com/en/products/adpd1080.html. It has integrated Rx and Tx path, you just need to supply the optics.
The optics is one of the things I was having an issue figuring out but I think I've found that I can use the LT1328CMS8#PBF and Vishay BPV22NF to do what I need. I just need to switch on if 14Hz IR is received.
Unless you have a better idea. I'm open for any suggestions. Thanks.
