WS-08

This weather station is reasonably accurate, by which I mean the probes will report temperatures and humidities that are within one degree Centigrade and 3% relative humidity of a scientific instrument. It is not terribly precise because the thermometer can err in either direction, hot or cold, and the same is true for the hygrometer, so I wouldn't imagine you'd want to use it for any industrial or scientific applications. If you just want to know what temperature it is inside and outside and/or in different living areas, it'll work just fine. I've had mine for a couple of months.A few finer points: while these record min and max temperatures and humidities, and either clears them daily or leaves them as records, they aren't really responsive to sudden weather changes. You can take one of these from indoors out into the winter air and it will take a while for it to respond, and vice versa. If a sudden cold front comes through, there's going to be some lag before your sensor starts reporting it (my guess is it reports its average reading over the space of a few minutes or so). Aside from the lag time, direct sunlight really warms these up so be careful how you position them.The wireless connectivity is mostly ok but occasionally wonky, especially if they're more than 20 feet or so away. It's low power for obvious reasons. By wonky I mean you can lose output on one of the sensors, temporarily, or until you move the sensor to a more favorable location.It can take a couple of tries to get all the sensors to get picked up by the WS-08, especially if any of the signals are distant.Assigning channels to new sensors or changing old ones is very simple, it's just a matter of flipping a couple dip switches and the instructions are right there.The battery cover for the sensors is secured into place with a screw, so have a Philips head screwdriver handy.If you dig in the manual you can find out how to calibrate the WS-08. Individual sensors can not be tuned or calibrated, but if you benchmark a sensor and find that it reports high or low by a set amount, you can modify that result on the main WS-08 screen (you just can't change what the LCD readout on the sensor displays).The bottom line is that these are an okay-to-decent product, which may sound like faint praise... but considering how cheap and shoddy many of these inexpensive weather stations are, it's a win. I'd probably buy it again if I needed to.

I purchased the Ambient Weather Wireless Indoor/Outdoor 8-Channel Thermo-Hygrometer with Daily Min/Max Display with eight sensors by Ambient Weather only a week ago and it has helped tremendously with balancing the temperatures in my house. I have a ranch with a basement and have been trying for years to adjust the vents upstairs so that every room, including the basement (which only has two vents), feels about the same. Silly me to try to do that without actually measuring the temperature! The great thing about the Ambient Weather Wireless Indoor/Outdoor 8-Channel Thermo-Hygrometer with Daily Min/Max Display is that it comes with the sensors that track both temperature and humidity. I have a "whole house" humidifier that I run upstairs in the hall near the bedrooms during the winter. Because I have a newer forced air furnace that constantly runs a low fan to circulate the air, I was also curious what the humidity throughout the house was. After only a week, and two adjustments to the vents, the house is now almost "perfect," with consistent temperature and humidity throughout. I mounted the display just above my thermostat control for the furnace so that it's easy to check the whole house and make any adjustments to the programming. I love the huge numbers on the display. It is so easy to see what is going on. The min/max feature is also brilliant! I love that I can see those values for each room to know truly what is going on rather than just right "now." The only feature this product is missing is a back light for the display. My thermostat control is backlit all the time (I wish it would turn off when not needed) and the back light makes a huge difference in readability, especially dusk to dawn. If this product was backlit, it would be perfect!! As is, it nearly is perfect, so four stars! As a side note, I also appreciated the simple packaging and there wasn't a lot of the packaging that I had to throw away, but only some of it is recyclable, another reason for just four stars.

This works fine and has reasonably good range between the sender/receiver. The sender has a screen showing the temp & humidity too, so if you put it on a porch or something, you get an extra outdoor thermometer/hygrometer. The display is big enough that you can read the large numbers for current temp and humidity across the room.I am, ultimately, not a huge fan of the display design. Basically, you get a lot of data for each station - current temp, daily low and high (or - if you want- an all time low and high), and the same current, low and high information for humidity.There is no way to make the humidity display into a second temp. temp display for the outdoor station. So that means you have one of two choices to see the info. A manual mode where you actually have to press a button to move from station to station, or a cycle mode where it constantly cycles the display between all active stations and the home station every few seconds.It turns out that the constant, automatic cycling of the numbers between inside and outside makes the display a bit distracting. I would not put this on my desk in my direct line of sight while in that mode, for example. If you just want a static display of indoor and outdoor temp, this is not for you. If you can put it somewhere where the cycling of the numbers isn't annoying, you'll get a lot more information out of this unit despite its relatively small size. So that is the trade-off with this unit.For me, it is fine, I put it where I wouldn't have to look at it constantly and could just consult it whenever I wanted to.
