Humidity Controller IHC200 Humidistat for Mushroom Greenhouse

Works great. I have it hooked to a dehumidifier in my basement. The dehumidifier is set to the lowest setting so the controller will turn it on and off. ie... the controller will turn the unit on/off and the unit will not stop it because of the dehumidifier settings. It is was hard to figure things out. But I wrote on the instructions on what the setting is. It keeps the setting even if the power is lost. I used different Inkbird at my parent's home for a light bulb attached to it under a sink so it would turn on/off and keep things from freezing - That is not this controller. Well worth the money.

This device works very well for my purpose of controlling a dessicant dehumidifier. I use this dehumidifier in a large "box" I built to dry the soundboards for the harps I make. Previous to purchasing this controller I used a humidity/temperature controller that one would attach to a wall in your home or office. This previous controller was awful at gauging the relative humidity in the box or a small room. It required that I constantly keep checking its measured RH to that of a separate, small humidity/temperature measuring device that seems to work very well and can be checked and adjusted fairly easily. This new humidity controller is designed very smartly and its measurements of RH seem to correspond very closely with the small measuring device, unlike the previous controller I used. Also very nice is the fact that I can now have this controller OUTSIDE of the box with the soundboard and dessicant dehumidifier. It has a short cable with an AC receptacle that the dehumidifier can be plugged into, but the actual humidity measuring device is attached to the controller via a fairly long cable. I have the humidity measuring device inside the box, and the AC cord for the dessicant dehumidifier comes out of the box to be plugged into the short cable off of this humidity controller. So I can easily check the RH inside the box without having to open up the box (and thereby raise the RH level). And you can adjust the controller to automatically turn on when the RH reaches 1% to 5% above the desired RH level set on the controller. The only thing I do not like about this device is the god AWFUL english instructions! Can the people at the company in China who make this controller please hire someone who can write clear understandable english, PLEASE!! You will eventually make sense of their nearly non-sensical instructions, but it does take awhile. Just so you know, their "differential" RH level means how far above the target RH the actual RH will get before the device turns on. You can set this differential RH level for 1% to 5% over the target RH level.

Perfect. My Dehumidifier works great but the woke programming inside it is terrible. In order for it to do it's job, witch it is quite capable of doing, I have to run it 4 time harder and longer. Now I set it on continuous run and use this controller to turn it on and off. Wow. What a difference. I live in a big 5th wheel in Florida, so I'm constantly fighting the humidity. In the last few days, my dehumidifier has run a heck of a lot less than it runs without the controller. I am actually looking forward to seeing my electric bill this month (-

This product works well once you've got it figured out, but the instruction sheet is an amateurish translation from some foreign language and very difficult to understand. I've used this controller for two years now to cycle a small humidifier on and off in response to the room humidity level and it does well at that, but the instructions need to be rewritten for clarity for English speakers.

Works beautifully to detect and give an easy reading on humidity in the space it's in. I used it along with a humidifier to achieve precise humidity in an aquarium and it's a beautiful piece of electronic. Pair it all with a digital timer and you've got a hands free fully automated humidifier system for your needs. Get this is you're on the fence. It's exactly what you need.

My wife runs 3 egg hatchers and our Inkbird controller makes environmental control for these a breeze. This unit is very easy to program, very accurate and dependable. The alarm system that notifies us when the humidity is outside our set parameters relieves from having to check the hatchers multiple times a day. We use a baby monitor placed near the controller with the receiver in the house, works great to notify us of any issues. After nearly a year of use, one of our controllers stopped functioning. I contacted Inkbird, they responded quickly and sent us a replacement within a couple of days. THANK YOU INKBIRD!!

The item is good, but their customer service is outstanding. They were very kind, helpful, and professional.

I've used one of these to maintain humidity levels in dry winters and dry air-conditioned air in summers by connecting it to two 1.5-gallon hot steam vaporizers. It's tenth of a percent RH control provides healthy humidity levels without peeling the paint off the walls.

Pour le commun des mortels quelques complications sur la programmation,mais avec du temps et de patience tout ce règle.L'instrument est très bien conçu et fonctionne tel que décrit sur le site. Je le recommande.

Funciona perfectamente

Using it to control a humidifier in a humidor. It's working flawlessly. The humidity sensor is super sensitive. Unlike analogue gauge, when I open the cabinet I see the humidity escaping in real time. And when I close it and the humidifier goes on I see it slowly climb to level. Amazing product. Can also attach a dehumidifier on plug b and if humidity goes too high it will start reducing it. Pro level stuff

Amazing product. helps me with proofing my bread without any worries of over humidifying the proofing chamber

It works like it should if you are hooking up a humidifier and dehumidifier that is analog digital, if its analog digital it won't work properly as it will turn off the humidifier and dehumidifier but the 2 units won't turn on again, the 2 units must have a on / off switch that if the power goes out and comes back on then either units turn on property hence the mechanical switch 😉
