Passive infrared sensors (PIR), use Infrared (IR) light to detect motion. Unfortunately for you, infrared light does not travel through glass so well.

You can probably replace the switches with those sensors, but you're going to have to do some creative wiring to work around the fact that they're not 3-way switches, but the switches you're replacing with them are. You'll likely end up with the light being on whenever either of the switches is on. You also might run into trouble if they ran the 3-way ...

Many occupancy sensors allow you to adjust the amount of time that they can't see you before they shut the lights off. I'm not sure what model you have, so I can't instruct you exactly how to adjust, but setting the timeout time to something longer would probably save you the trouble of building something to circumvent it. For example, a panel on this ...

Unless the sensor/light is connected directly to power, the switch will always have to be in the ON position for the light to come on. The switch is installed to interrupt the ungrounded (hot) conductor, so that when it's in the OFF position no power goes to the light. If you want power to the light, you'll have to leave the switch on. In other news, ...

There are more choices than you might think http://www.leviton.com/OA_HTML/SectionDisplay.jsp?section=38557&minisite=10251 I am thinking you might want a 3-way, manual on, auto off. But whatever Pattern, Coverage, Time delay, or Switch type, you will likely find it here. You can get leviton stuff anywhere, it is likely one of these would be a special ...

You didn't say if you already had lighting in your closet or not. If you don't, I would suggest buying a stick-up (battery-operated) LED light with a motion sensor. (In my area, most retailers have several models like this.) Most interior motion sensors are combined with a switch, so if you don't want a switch then you may be out of luck.

The motion sensor's circuits are probably being confused by a voltage spike caused by an inductive kick from the fan. The voltage levels in the device are disturbed, reversing some voltage comparison so that the light is activated. The problem can be attacked at either end. Containing the surge at or near the fan, or preventing its entry into the motion ...

What you are looking for is a VOC (volatile organic compounds) monitor or a IAQ (indoor air quality) monitor. They do exist for residential applications and are way much cheaper than the industrial counterparts; however, their detection/sensitivity level may not be as great. You can try your luck by searching for "iaq monitor" on Amazon and eBay. Prices may ...

Well is it to be used indoors or outdoors? Because a lot of the technology is generally used for detection indoors. That is not to say you do not get them for outdoors it's just in my experience the ranges are more limited. You get detectors that work on four different technologies they are:- Passive Infared (PIR), Microwave, Ultrasonic and Tomographic. The ...

Many models seem to be sensitive to power surges. A lighting storm or frequent episodes of lights flickering have destroyed several of my sensors over the years. Some models have a switch on the detector head. The switch may allow you to test the unit by placing it in test mode. If that option is not available you will have to disassemble the fixture and use ...

This tree, not the one you should be barking up, is. PIRs do NOT work though glass. Put it outside.

Put the sensor in the space you are trying to light, and suddenly this "common need" becomes "not a need at all" which is why you can't find them, since that's how it's done, when done conventionally. Either move the switch into the room or get a remote sensor switch and put the sensor in the room.

No, such an arrangement will either flat out not work, or have very poor reliability. The motion detector logic requires full uninterrupted voltage and a dimmer switch is going to inject noise into the power which will disrupt the motion logic or its sensor. Additionally, even if the motion sensor continued to work, the cycling of the light on and off ...

It defines the physical size of bulb that can be accomodated. The most commonly used A-series light bulb type is the A19 bulb, which is 2 3⁄8 inches (60 mm) wide at its widest point, approximately 4 3⁄8 inches (110 mm) in length, and has a one-inch wide (type E26, i.e. approximately 26 millimetres wide) Edison screw base. From Wikipedia Any CFL that ...

After wrestling with 3way (i call them "two pole" but to each their own) switches I have learned that the only way out is patience and testing. Don't trust the wire colors. Unhook the switches from both sides (or just one switch if you are sure the other hasn't been altered since it was working), put wire nuts on the open wires, and power the circuit back ...

Most people find that a switch that activates when the closet door opens is simpler, easier, and more efficient than what you are describing.

If you have one nearby then I think you should have a look at Ikea. They have a range of affordable low voltage LED lighting systems many of which have integrated sensors which turn on/off the light when a door is opened/closed I understand they use an infrared sensor of some sort to detect the proximity of the door. Links are for Ireland, but I'm sure you ...

The blinking red light on the sender would indicate that they are mis-aligned. The best way to test this is to remove them from the mounting brackets and hold them a couple of inches apart with the sensors aligned. Have somebody hit the door closer, then point them away from each other. If they work as expected that way, you'll just have to fiddle around ...

Can't find that one. Another company's model that gives numbers (after looking more - MANY don't, which seems sketchy) claims 10mA @ 24v, or 0.01A x24V = 0.24W - less than 15, yes; Quite a bit more than 0.002, though. Whether it's actually worth buying (since you mention that it's expensive) would depend on how much you pay for power and how many hours it ...

If this is in your home office where you have some control over things it seems silly to have to design or build some gadget to override the occupancy sensor. The whole purpose of the sensor is to shut the lights off when you leave and forget to do so. You could just as likely leave and forget to turn off your override gadget!! In this instance I would ...

You will have to install the motion sensor (if it is rated 110v) in the feed to the low voltage system. that is, hot going to switch, then motion sensor, then low voltage transformer then low voltage lights. that is, sensor powered by 110v, feeding transformer

All motion detectors have an override mode. Typically this is done by either flipping the wall switch off/on in a certain pattern, or by a switch on the motion head. Thing is, when you put it in override mode every one I have seen reverts back to motion after the next night/day cycle. I have NEVER seen a motion detector that has a permanent manual override ...

You can use one sensor for each light (looks weird but cheaper than below) -- buy sensors that fit the standard gang wall plate and buy a two-gang wall plate to cover both. Alternatively, you could move both to a single occupancy sensor using a "dual relay" occupancy sensor. More expensive, but looks better and saves you from messing with wiring between ...

A 2-gang box simply holds 2 single-gang devices. You need the single-gang device, the hard part will be finding the correct faceplate to use.
