Ambient Weather WS-3000-X5 Thermo-Hygrometer Wireless Monitor w/ 5 Remote Sensors - Logging, Graphing, Alarming, Radio Controlled Clock

Works great. I had a minor programing issue, and the manufacture customer service was quick to respond to my email and resolve my issue. Unit is perfect for monitoring my outbuildings during winter from the house. Thanks again Ambient for great customer service.

This is simply the coolest and best Thermal monitor I've had the pleasure to own. Let's break down why- 1). It's super easy to set up. Just put batteries in all of the remotes. Set the dip switches for what channel you want them to be. THEN plug in the base station. It set's itself up, including time, (although you have to set the std time) . Then you see 5 channels displayed within minutes. And for simple basic temperature display, you're done! Distribute them up to a football field away (line of sight), or ~100 ft thru walls etc. 2). Each sensor has a local display, so you can pick it up and gawk at it on site, instead of having to go back to the main unit. I like that. Temp and Rel Humidity. And you can read heat index at the main unit (if set up to do so). 3). It graphs a history of all 5 (up to 8) sensors at once, in color. Up to 72 hours. And it can store a history for years on a micro usb chip (just buy a small cheap one-not needed if you don't want this). ....now if you have the time and desire: 4). It has temp/rel hum/heat index alarms hi&lo for all 8 channels! 5). The display for all 5 on-screen channels (and 6-8) can be independently programmed to display temp/hum/Heat Ind for each channel (or all at once - it scrolls for that). So it's a super flexible display. It's all in the manual. I recommend grouping them all together a few feet away from the base unit, then you can calibrate them to each other (what I did - to the middle one), or to a liquid bulb thermometer. Most of mine did not need more than .2 degrees F of tweaking. Then scatter them about your environment and have fun watching the graphs. I use lithium AA batteries for their long life, but a requirement if any of your sensors expect to get much below freezing. So I've got 1 at the base in the kitchen, 2 Outside, 3 in the bedroom, 4 downstairs and 5 in the cave. Now the one subtle downside: after you hit the menu key, there's a + key that functions as 'Enter', which takes you to screens where often you can increase '+' or decrease '-'. So it's confusing at first because you'd think + is incremental, not 'enter'. They should have come up with an 'enter' icon different from +. Didn't take me long to figure that out, but that was odd at first. Just know that and you're good. This is a great unit for basic users that want 5 spots T monitored (up to 8), or for tweakerheads that want more control. Best Thermometer + more I've ever owned. (The last was an Ambient Weather one too).

While it was expensive it was the only multichannel data logging thermometer I could find.

I have used the Ambient Weather WS-3000-X5 for a little over a month now and haven't experienced any of the negative issues I've read about in some of the comments submitted. The instructions were clear and the set up was simple, although I haven't used the pc connection extensively but the installation was straight forward and easy. The display was a little smaller than expected but no problems reading the info, and it doesn't take up much space on my desk. The sensors and receiver all appear well made both in form and function. When placing any sensor outside you should take care in positioning them so that the don't receive direct sunlight and are protected from rainfall or other water sources. Initially I set the units up in my study arranging them with at least a 5' distance from the others and set up to display the temperature and humidity, then left the room and waited. Around an hour later I returned and the temperature readings had settled out and were the same with the exception of two being 1/10th of a degree higher than the others and in agreement with the settings on my air conditioner thermostat. The humidity readings were displaying similar readings with each other, no more than 1/10th of a percent difference. After monitoring them for two days I relocated one to the attic, the garage, my home gym, and my gun safe, keeping the 5th in my study temporarily, where they've been for the past month. All have been operating well within my expectations. With the history graphing it is easy to visualize changes that have occurred as you would expect the differences in temperature and humidity to be in the respective locations throughout the day and night. I have not had any sensors drop connection with the receiver at this point. I am unsure what the battery life will be in the sensors but not really worried as the batteries are easy to replace. This morning I moved sensor (ch1) from my study to an outside shaded area of the backyard, The receiver indicated the correct outside temp within 15 minutes as you can see from the picture. Within an hour the humidity reading raised from 42% to 54%. While the attic (ch3) shows 57% humidity, the attic generally indicates 20% less humidity than weather sites report, probably because my ac and furnace units are located in the attic. I expect (ch1) humidity reading to continue to rise as it updates. Overall I am very satisfied with the devices and price point, I definitely recommend the product.
