Are sensors new and how are they packaged? (picture?)

They're new and made by Chamberlain. They're packaged in the human-proof plastic packaging that is so common. Installed 1/2 [the component that wasn't working] over 6 months ago, so NO picture=sorry.

They are packaged new with everything needed. Just like you'd get them from lowes

2 sensors came in the box. I actually need 2 sensors and ordered 2 boxes by mistake. Returned the second one.

No nothing comes with the sensor. They were susposed to remove them from selling as they have issues. I returned mine as they didn't work at all.

Sorry. Don't buy it. It consumed batteries (costly) and after a while the sensor is not functional anymore as expected. Better buy one with foot mechanism. It will last longer. Hope that helps.

As far as I know, mine was new. They work great and the price was unbeatable.

These sensors should work with units that have 2 wire connections to the main system board. They are quite simple and work very well. You should not have any trouble replacing your old, damaged, non-working sensors.

I want to know this too, I don't see anywhere to purchase the sensor by itself.

Perhaps not, I had recently ordered two knock sensors and intake gaskets, they where combined in one box, the sensors was tucked in the corner with some air pillows not much protection IMO. One thing I will mention they come in plastic bags from manufacture as well no box and I`m sure the person stocking your order from Amazon has no clue the sensitive nature of the sensors. BTW both of mine had no problems but I'm sure one keeps in the back of there mine, as I did `I hope they work' as it's a fare amount of work installing them just to find out they are defective from miss handling or poor packing.

I have not done much with the sensors to date. Most of the sensors are simple digital/ analog I/O interfaces which would just require an appropriate I/O selection on the microcontroller. If you have questions about a specific module, I could take a quick look and let you know. I had the same reaction with the lack of documentation but I am an electrical engineer so I am not particularly worried about figuring out the details.

All the hardware required for installation is included with the sensor. Unfortunately all four of the sensors stopped working!

I agree with Jose. We also bought 3 and 1 was bad. Honeywell replaced it with one that works. Looks like the magic number is a 66% rate of good sensors. Hopefully Honeywell will improve their quality control. The units that function properly work very well.

Yes, it is the photo-sensor.. Just return the item and get another.. A few of the items have quality issues.. 2 different revisions of the board.. Overall good and reliable product when you get one that works.. Do not forget to remove the outer lenses cover and silicone seal the threads. Will short-out the electronics should condensation get inside. I have 8 of the units working now for 1-1/2 years thru sub-zero to 105 degrees..

Yes, but the sensors only work for a few weeks, I had to returned mine. It's not worth it. It's will cost you more to install than the product.

I have had mine for almost a year, and have had no issues with it. So, I don't know if mine is a "new" unit.I would guess if is aluminum, if that is what you are seeing in the pictures.

I have no idea. You would have to contact Amazon or the manufacturer. My feeling is, why not get the sensors? They can't be that much more money and then you'll have extra parts just in case.

no, only one sensor comes in the box, to find the exact replacement for your vechile which, it is either threaded or flanged mounted, go to the denso web site

YOU GUYS ARE WRONG AND I BOUGHT IT WITH THE INTENTION OF IT BEING 4 SENSORS, NOT 1!!! I picked up my package and there was only 1 sensor
