I purchased my InkBird IHC-200 February 2022. I have multiple InkBird products and count on them for accuracy and reliability. My IHC-200 had a fatal malfunction, this was past the warranty period. InkBird did not even blink twice before sending me a replacement. Customer service is a priority for me when I decide to purchase from a company. I will continue to do business with InkBird without any reservations. Thanks InkBird.

We purchased 1 initially to control the humidity in a 5x5 grow tent that was consentally either at >98% or <20% no matter how we ran our humidifier, fans, and exhaust fan. Received the controller and immediately set it up. We live in a very dry climate and have no need to use a dehumidifier in this particular tent. Set work 1 (again not using work 2) to 58% with an 8% range. And just like magic we had 48 hours of perfect humidity. Decided to buy 2 more for our flower tent and drying tent. Set them up and calibrated 1 because it was a little off. Almost immediately started having problems with our drying tent. Couldnt get it keep the humidity above 25% (even the unit itself was showing low) when the humidifier was plugged into the controller, but if we run the humidifier directly into an outlet it would climb up approximately. The flowering tent isnt holding the settings/% we program. It goes right back to default of 50% with a 5% range. Luckily its default is close to what we need, but we shouldnt have to be forced to keep it that way. It completely defeats the purpose of having this all together. Now, on day 5 we wake up to or our original controller in our vegetative tent not functioning and running to humidifier all the time. It was 99% in there, even though the controller is still show our 58% with 8% range. I tried changing it down to 50% and 5% and the unit goes right back to showing 58% and 8%. So, now we have 3 controllers and not a single 1 is working as it should. I am going to replace these 3 as defective and try again with their replacements but I dont have much hope that they will do what theyre supposed to do. Will probably end up with 0/6 and will update after the replacements get here and are set up.

Very dependable, easy to navigate and goes what it is supposed to do A+

Bought on 2/2/17 for dry aging/salami fridge. I used it for 2 months without a hitch for dry aging steak. Its been off for the past few months, then when I wanted to start a few hams it wont work. Its an intermittent short circuit happening inside the controller itself. I contacted InkBird to see what develops. I will update. Update 9.30...they sent me a new unit stating the black sensor can go bad if it sits for a while while unused. I wired my controller through the fridge bottom so I just swapped sensors, not touching the unit. Seems to be working fine. So I guess if I ever unplug the fridge for a while Ill take out the sensor

If you’re here because you saw willy myco setting up a 5x5 tent, I URGE you to join a cultivation group and get real advice on how to set up a grow tent before you waste $600 dollars and weeks of your time. The problem with this sensor is that the plastic casing of the sensor allows moisture to bead up on its surface and stay there, falsely giving you a reading for near 90% humidity or even above. It’s not an easy fix because the only thing I’ve found to try and correct this issue is wiping the sensor casing down with a dry, sterilized towel twice a day. That’s really tedious considering everything else about my setup is fully automated and controlled from my iPhone. The fact that the sensor controls when the fogger comes on or cuts off is really the only reason to try to figure out a way to jerry rig this product, but as is it’s not really functional.

I love my humidity controller. It works perfectly for maintaining the perfect humidity in my terrarium. I’ve tested it against other Hygrometers, and it’s pretty accurate, plus you can tune it. Recently used it to run a room humidifier, to increase the humidity in the bedroom at night. The possibilities are endless! I wish it had some smart integration, I would like to see a historical graph over time. Also, disabling the Alarm for high or low Humidity would be nice as well.

If you are dealing with a situation with high humidity, this unit will without fail alarm and turn off your dehumidifier / fan, making it mostly useless. You cannot set the unit to not alarm, so you will have to listen to it blearing, knowing that you now have to manually have to get power to your dehumidifier / fan. You can set the calibration down by a max of -10%, and then set your dehumidify set point down a corresponding -10%, but amazingly it will STILL alarm at high humidity and shut off your dehumidifier / fan. Amazingly disappointing.

Would be 5 stars if it did not present the “Err” issue the first2 weeks of use. Fortunately an amazing buyer here (thank you) found out that it is the prone being a little bit loose. Once I removed the cap and shakes the sensor and tighten it up, I never had this issue again in 2 months and counting.

Didnt have instructions. Had to search the deepest corners of the internet to find it. But YouTube saved me. Great product just needs instructions.

This is a simple On/Off controller with adjustable hysteresis. Accurate readings and control require a minimum amount of air moving across the sensor. The Relative Humidity will always fluctuate around the set point with this type of controller ( Or any controller). With some tweaking of this controllers settings and the output level of the humidifier. I can get +- %5 RH. Good enough for most mushroom cultivation fruiting tents. It is a good value compared to a $200 PID controller that cannot do much better.
