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. Review: Works very well - 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. ## Features - The humidity controller ranges from 5 to 99.99% RH - It's a digital humidity controller, easy to read; Accuracy: plus or minus 3% RH - Designed for use in a mushroom, grow tent, or greenhouse; It also works as a reptile humidity controller - You could plug a greenhouse humidifier or a grow tent humidifier, and a dehumidifier for a grow tent - Switch the modes between humidification and dehumidification automatically; Supports calibrate the humidity accuracy ## Technical Specifications | Specification | Value | |---------------|-------| | Brand | Inkbird | | Color | IHC-200 | | Display Type | Digital | | Item Weight | 15.84 ounces | | Material | Plastic | | Material Type | Plastic | | Voltage | 120 volts_of_alternating_current | ## Product Details - **Brand:** Inkbird - **Color:** Ihc-200 - **Item Weight:** 0.99 Pounds - **Material:** Plastic - **Voltage:** 120 Volts (AC) ## Images ![Humidity Controller IHC200 Humidistat for Mushroom Greenhouse - Image 1](https://m.media-amazon.com/images/I/71O34JbGu8L.jpg) ![Humidity Controller IHC200 Humidistat for Mushroom Greenhouse - Image 2](https://m.media-amazon.com/images/I/61a6nq1nEjL.jpg) ![Humidity Controller IHC200 Humidistat for Mushroom Greenhouse - Image 3](https://m.media-amazon.com/images/I/51XtXhaIlYL.jpg) ![Humidity Controller IHC200 Humidistat for Mushroom Greenhouse - Image 4](https://m.media-amazon.com/images/I/61bF96WRAkL.jpg) ![Humidity Controller IHC200 Humidistat for Mushroom Greenhouse - Image 5](https://m.media-amazon.com/images/I/81c2qHKsHfL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Works well *by D***D on June 3, 2026* Works great.

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 (- ## Frequently Bought Together - Inkbird Humidity Controller IHC200 Humidistat Mushroom Greenhouse Pre Wired Outlet Dual Stage Humidifier Dehumidifier. - Inkbird ITC-308 Digital Temperature Controller 2-Stage Outlet Thermostat Heating and Cooling Mode Carboy Homebrew Fermenter Greenhouse Terrarium 110V 10A --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/31349750-humidity-controller-ihc200-humidistat-for-mushroom-greenhouse](https://www.desertcart.us/products/31349750-humidity-controller-ihc200-humidistat-for-mushroom-greenhouse) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-08-19*
