    • Better than I expected & both the unit & probe read temp. & RH. Highly Recommend!
Style: Thermometer with External Probe
Review Image by Yuriy
I was skeptical of Vivosun anything because everything I tried in the past was less than average quality and stick with AC Infinity but couldn't find a reliable temperature and humidity sensor that also comes with a probe that also reads temp and humidity. Unfortunately, most devices with a probe their probe only reads temperature, not humidity even though the unit itself reads both but not the probe. Thankfully, this Vivosun AeroLab TH1S is accurate right out of the box in both temperature and humidity (compared with 10+ thermometer/hydrometers in grow room & curing bags) but in case you need to calibrate it, you can certainly do that through the app which has a ton of other great features including Bluetooth connection and optional Wi-Fi connection via a small USB stick (cheaper option) or a controller 🎮 to monitor with other Vivosun products. ⚠️ NOTE ⚠️ The temperature and humidity stabilizes a bit slower than I'd like but faster than others. It's not terribly long because it gives a very close reading and then over the next 10-15 minutes it stabilizes and the readings change a couple degrees and a few RH percent ... show more

    • Game changer
Style: Thermometer with External Probe
So I bought this little unit to monitor the VPD in my grow tent and trust me it works as advertised. Now the details: I have attempted to 2 other grows in the past but never had the results I wanted. So, this time i decided to see if AI could help. And it has bigtime, but through my reading I kept seeing the three letters VPD. So, what is it? It stands for Vapor Pressure deficit. It refers to the amount of water in the form of vapor in the air and is displayed as kPa. The ideal VPD changes as your plants mature. Whereas a seedling requires a VPD of 0.6 kPa and an adult ideal VPD is about 1.5 kPa. Bottom line. A few minutes after I had this set up, I found I was too low for the growth stage of my plants. And now (a few hours later) after a couple tweaks of my humidifier and my exhaust I am right at 0.8 kPa which is exactly where I need to be. Oh, and by the way there is an app so I can see this info on my phone. It is however only Bluetooth but does track all the details of the grow. Is it perfect? Well, no, what app is? But it is very useful and connects with other Vivosun Smart Grow System products. So much so that I may just shift from my current product line. And to get it for less than $20 Game Changer! ... show more

    • The Bluetooth is aweful and gives false readings
Style: Thermometer with External Probe
Not great! If you’re okay getting your readings while standing next to it, then this is for you. But the Bluetooth is not good. I kept disconnecting 1 floor up from this unit in my basement. I kept having to go down to the basement to reconnect. I’m returning it and will get a WiFi hygrometer because if I have to be next to it to get a reading, I would just have the basic hygrometer without “Bluetooth.” ... show more

    • Perfect for Incubators!

Incubators are notoriously off when it comes to temperature/humidity readings which makes ALL the difference on a successful vs failure hatch. I just wanted something simple with a probe and having used Vivosun for gardening supplies in the past decided to go with the brand again and was not disappointed! First thing I wanted to do is make sure the Vivosun was accurate, placed it next to a couple other temperature/humidity monitors I have in the house and it was pretty spot on. Then I placed the probe into my incubator and just as I knew was gonna happen, both temperature and humidity were off. Upped my incubator temperature and adjusted humidity as needed and had a wildly successful hatch at 94% hatch rate (17 out of 18 eggs)! Will absolutely keep using it for all my hatches and I’m happy to have something that’s dependable and easy to use. ... show more

    • Bluetooth range issues and dropping from MY DEVICES
Style: Thermometer with External Probe
I have three of the THB1S units. Two work, but one keeps dropping from MY DEVICES on my phone. Additionally, the Bluetooth range needs improvement — I sometimes have trouble connecting to the devices when I'm several rooms away.
