LED Sensor

 

Does anyone know of a good led sensor. I am trying to get feedback from a gate entrance. It is older linear gate device and the only fb I see is an led light on the board that is illuminated when the gate is open. Would like to put an led sensor over it that has contact wire to send feedback to Crestron if gate is opened or closed.

Thanks
 

I use these photoresistor relay modules for various things in my own system https://www.ebay.com/itm/164296219470?mkcid=16&mkevt=1&mkrid=711-127632-2357-0&ssspo=1baxik6MTeS&sssrc=2047675&ssuid=&widget_ver=artemis&media=COPY

For instance I have one with the sensor over the "Done" LED on the panel of my washing machine and it triggers the relay which is ran to an I/O on my processor so I know when the laundry is done. Works perfect.
 

Personally, I would use a garage door magnetic contact for this.  I've had great success with these Seco-Larm SM-226L-3Q Overhead Door Magnetic Contact, 2.75-inch Gap, Open/Closed Loop Circuits (3 Wires), 24" Armored Wire Leads, Weatherproof https://a.co/d/8CzcIxW

I have used this ELK sensitive relay for many projects including wiring it in parallel with an LED to get a contact closure when an LED illuminates. I am getting reliable operation with only 1 milliamp driving the input. ELK-924 12/24 VDC, W/ 1.2 MA Trigger, 125 VAC, Sensitive Relay https://a.co/d/7r9hzvS

You may also have success using this light sensor - EIKS Photosensitive Resistor Module DC 5V Photo-resistor Relay Switch https://a.co/d/iFDBQb7

Please share what worked for you.

Can you solder wires to the led contacts on the board. It should be around 3.3 v dc and use a 3v relay for contact closure?

FYI - I've purchased some of the recommended photo-resistor relay modules.  I plan on trying them out and writing an article about the whole topic if they work out. 

Thanks

I've used these for monitoring power LEDs on cable boxes, a little more finished look then those posted above if using where it may be seen.
