I have purchased a little environment tracker which tracks Humidity, UV light and Temperature. I wanted to write a review about it because I find it really cute cloud-shaped device which I can place it in any place I want and measure HUT and I think it worths its money ($25-$55) in my opinion.
The device’s case is made of plastic and on the box it mentions that it is drip, slash and sweat resistant IPX4. However I wouldn’t mind paying more for an anodised aluminium case.
It comes with a Stand in case you want to place it on top of you night stand, table, bookcase, etc and with a Lanyard in case you want to carry it with you. It also has a nice physical feature which is a magnetic back, not enough strong to hold itself but if you own a small neodymium magnet you can combine them and use it on your fridge or placing it on your clothes like a wearable…
As I mention before I find its cloud-shaped form really cute but it doesn’t make it really attractive to the general public or formal enough to wear it with you everywhere.
It works with a coin-sized Lithium battery CR2032 and it claims that can operate up to 6 months on normal usage. Although I would love if it had a small Solar panel on the front next to the UV sensor, infinity energy.
Temperature: The temperature sensor is quite accurate but don’t expect high precision±2ºC. I have compared it with 3 more devices and they mostly coincide.
RH Humidity: It’s less accurate than the temperature sensor by ±5% based on my experiment, but it is Relative Humidity as its name says it is relative!
UV: A bit disappointed about it to be honest and I will explain why. I think the way they have place it on the device isn’t the optimal way to read always the correct UVI value from sun. You see sun’s rays hit the earth on an angle and the device must be on 90º angle with those rays if you want the device to tell you the highest value (highest=right value). One more thing that I don’t like is the frontal face because it can cast a shadow on the sensor and as a result no UVI reading.
The iOS app that I have been using is super nice, but with some small bugs in the history tab. The app is divided into 4 Tabs. The first calculates the time you should be exposed on UV rays to avoid sun burns, the second is the History tab with Day-Week-Month overview of the HUT, the third tab is the main tab with all the current stats plus a little plant that tells you if it’s confortable or not and the last one is a social tab with a camera integration.
It uses Bluetooth 4.0 technology and it works with iOS 6 or newer devices and any Android 4.3 or newer.
P.S The device is under the brands Adam Elements CliMate and Rooti CliMate.
