User questions & answers

Question:	Will this illum a led and send to a ext dev for when ir strikes reflective tape or connection is interrupted. I have 5 to 15 volts 150mA
Answer:	Hello Jason: I think the question you are asking is: Can this device be used to trigger an L.E.D. by sending a signal to an illuminating circuit (i.e. switching circuit) if and when the built-in Infra-Red led transceiver's reflected beam is broken or interrupted by an object or obstacle placed in the path? Is my assumption correct? If so, then yes it is possible to perform this task with this device as the sensor/activator front end to either the Arduino (for processing) or an adequate momentary logic circuit and an IR reflector designed to make this happen...Kind of like an "electric-eye" type of intrusion detecting device. Hope this helps.
Question:	Will these work with a Raspberry pi
Answer:	The quick answer is YES, they will. The longer answer is BUT, there are not that many I/O pins on a Raspberry Pie so it would be easy to use up your pins with just a few of the IR devices. So possibly a analog or digital multiplexer would allow you to use say 8 of the IR devices using 3 output pins to select which IR unit you wanted and a pin to read the value of the IR device. There maybe some Raspberry hats that have this kind of thing all figured out though.
Question:	Will this work for a 24 volt solenoid
Answer:	These devices, by themselves, will not handle a 24 volt ac or dc solenoid. The output of these devices is strictly a T.T.L. or RS-232C level. You might want to interface a trigger interface that could handle the current involved, to do the job; which could easily be done. But the answer to your question is no, they cannot by themselves handle 24 volts. Hope this helps.
Question:	What is the repeatability of these sensors? I'm trying to use them to measure length
Answer:	You can't measure length with these sensors. They are photo-switches. The emitter reflects off the surface back into the photo-diode. You set the level at which the photo-diode meets the comparator threshold by way of potentiometer on the sensor. So how "repeatable" is the sensor - fairly under ideal conditions. You can detect the position of an object to a few millimeters repeatably, but the "repeatability" is affected by a number of other factors:1. Distance - as the distance increases the reflected light decreases (as a square of the distance - both out and return) so the sensitivity wrt distance drops. 2. Emissivity of the surface - it has to reflect the IR ligth afteral3. Angle of the surface relative to the transmitter - a smarter man would say something about solid-angles4. Ambient light - probably the worst gremlin, especially as distance increases and you drop the sensitivity. In my experience, when you get out past 20 cm, sig/noise goes to hell outdoors.5. Direction/speed object is moving - There is a bit of a hysteresis, We've never noticed any timing delay, but YMMMV.I'm sure there's more, but you get the idea.

User questions & answers

Question:	What do these sensors do? What do they react to
Answer:	I have 4 of the blue chairs, the color is not teal or navy. The photo is almost exactly how it looks in person.
Question:	Can the sensor range be adjusted
Answer:	I wouldn’t say they would be too small, and they are comfortable enough to sit and talk. This is definitely not a lounging chair, or binge tv chair. We have four of them in our office, for customers, so they do not get a lot of continuous use like that. They are great looking and get a lot of compliments.
Question:	How can you tell which prong is ground, neutral or hot
Answer:	They are definitely more for looks. Comfy isn’t a word I would use to describe them. I’m 5’8”. It is definitely a nice chair though.
Question:	How long do these supply power after triggering
Answer:	It's faux velvet. The chair pad has a zipped cover that can be removed.

User questions & answers

Question:	How long do the sensor batteries last before needing to be changed
Answer:	I have owned this product its been in constant operation 24/7 for 6 years now. My sensors have been outside ever since the day they came out of the box. Zero problems from any of the 5 sensors I have in use. I change out the batteries in each sensor twice a year to ensure that I avoid problems. So I know that the batteries are good for 6 months or more. CAUTION....PLACEMENT OF SENSORS IS CRUCIAL FOR THIS PRODUCT TO BE A USEFUL TOOL IN HOME SECURITY! It will take a bit of trial and error as the sensors are highly...well...sensitive! Be patient and they will become a valuable part of your security system.
Question:	Where can I purchase the AC adapter for the receiver
Answer:	I bought a Gemini universal adapter years ago.
Question:	How loud is the alarm mode
Answer:	The receiver has an "alarm" mode and a "ding dong" mode. It is also equipped with another switch that controls the pitch of the setting you choose. These options are loud, normal, and silent. Silent mode causes the light to flash only. NO MATTER WHICH SETTING YOU PREFER, I GARAUNTEE IT TO BE LOUD ENOUGH THAT IT WILL NOT BE PLEASENT ON THE EARS! Excluding silent mode obviously. And because of its range and expandable features, you can place a receiver on your night stand. Don't know abt the other answer, but if this alarm is set to loud and happens to go off when im sleeping, the first thing im gonna do is take out the sensor with my 9mm. YES THIS PRODUCT IS LOUD!!
Question:	What type of batteries
Answer:	The kit I received includes a window/door sensor which requires a CR2032 "button" battery. The chime-unit requires two AA batteries. I had mistakenly read these prior answers to imply everything *except* a button battery. (I prefer to avoid items where a button battery is used and a pair of AAA batteries would have sufficed, mostly out of safety for my grandchildren and the serious medical complications that can come from swallowing one.) I may still have made the purchase. It's just that I would have spent more time looking elsewhere on the off chance of finding a unit without button batteries.

User questions & answers

Question:	Has anyone used these for a gate opener? I'm not sure how to install on our Co-z gate opener
Answer:	We started w that sauna. However, when we tested it for EMF's we found it was way over the safe limit. We returned ours and purchased a $4500 safer sauna for 2. We love it. As I recall, it would fit someone that size, but then you'd be mighty close to the heaters.
Question:	Will this sound a loud noise, from the device(s), when the beam is passed through
Answer:	I found this in the reviews "EMF rating between 0.07 - 13.5mg. I saw the highest emf rating at the center of the sauna 12-13.5emf"
Question:	What is the maximum distance between transmitter and receiver
Answer:	I have done it both ways. I thought the infrared rays would be beneficial for the facial skin as well. I use a much smaller stool for the inside.
Question:	Will this wire into a home security system panel as a usual window/door zone? More specifically an Ademco Honeywell system
Answer:	I would not recommend using any steam. After approximately 7 minutes you will feel the internal sauna working! The panels on the side produce the heat which has far greater benefits than just steam. No steam necessary. During a heavy metal detox, I used the same sauna. I removed the chair and put a towel on the floor of the sauna and sat in the middle meditating with the top closed. Rarely, if ever could I make it the entire time. So far it is working great! I love my purple sparkles!
