Anyways: what kind of technology is used for the sensor? How many years is it stable for???

Maybe that's a question for the manufacturers. Western humidor has a call line for questions at 1-877-627-4798. I own 4 of the caliber III. For over a year now, it's been running steady and accurate. Reacts almost immediate to humidity changes.

Next week my SmartThings will turn 1 year old. Here are my current battery readings for each of my original devices and their function: Motion sensor in my living room that gets lots of use: 13% (uses AA batteries) Garage Door Smart Sense Multi (this product) which gets opened and closed at least twice a day (maybe more and sometimes stays open all day): 50% (uses AAAA batteries) Garage People Door SSM (this product) (entry to/from garage into house) which gets opened at least a dozen times a day (wife and kids): 50% (this is after an entire year!!) Garage Motion Detector which sits in garage for security purposes: 13% (uses AA batteries) So despite some who think that the usage determines battery life, it would appear in my situation that my devices are wearing evenly despite differing usage patterns.

I also have one sensor dead two years after purchase on Amazon (P409S Retrofit TPMS). I am considering getting another complete system since if one battery is gone, can the rest be far behind? Given the good performance of three systems in three of my vehicles I might spring for another complete system. Peace of mind is priceless.

Mine had been working just fine for about two years. Battery life is still very good and no recharging problems what so ever. And the pressure sensor worked great until now ! It's kind of hard to ignore the sensor's very bright red light on the display !

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

Same here, it's 10 months old and the sensor is broken. Seems to be a trend! Anyone contact the company about fixing it or warranty info?

I use temperature monitoring on a multi-sensor and it provides updates every 20-30 minutes, I believe, unless there is a serious change in temperature.

Just bought this model, so can't answer long term. However, I have 3 other HZ lamps with dusk-to-dawn and motion sensor electronics and have owned other similar lamps in the past. In my opinion, the electronics are reliable for 2-10 years. Plan to replace these lamps every couple/few years. They don't work well with any other than incandescent bulbs. Put a 40-60 watt bulb in it and plan to change bulbs a couple times per year. If you don't expect it to last 20-years and don't expect bulbs to last 5-years you should be okay.

Certainly- The platform (R Pi, Arduino, chipKIT, etc.) isn't a central factor. The important points are: type of sensor (digital vs. analog, though most sensors are analog), operating parameters (temperature, environment, etc.), power requirements (if an active sensor vs. a passive), and dev board inputs (analog, analog with PWM, digital).

I've had mine over a year now. Never had a single problem with it. Accurate and dependable.

I purchased several motion sensors, and some are able to detect motion at 20 feet and others are only able to detect it at 12 feet (even if I adjust the sensitivity). I also found some units to be more prone to activating false alarms than others. This all points to poor quality control and testing with their production, but most of units have proven to be very good and continue to perform well after 18 months of use.

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.

I bought only the sensor. I'm on my second sensor now I got about a years use out of the first one.

Sorry our trees are to far away to trip the sensor. Our trips are from people, pets and vehicles, the larger the object the farther away the trip seems to happen. As a side note still running on batteries installed 10 months previous.

If I remember correctly there is an adjustment screw inside the sensor that determines how long the sensor stays on so I've checked that before I got another one

Seriously, this sensor works only part of the time 5 feet or 100 feet away. I strongly suggest you use a reliable solution for anything that is important. It will false alarm, or lose track of the sensor or not alarm when it should. Then sometimes it works fine. I have 2 base units and 4 different sensors. None work reliably.

That's approximately the date the sensors will start to deteriorate. It will start beeping and keep on so, until you change it out. It will also keep beeping even without a battery for some 3 or 4 days.
