Inkbird Humidity Controller IHC200 Humidistat Mushroom Greenhouse Pre Wired Outlet Dual Stage Humidifier Dehumidifier

Great product, keep the humidity at the level y ou set

This humidity controller is OK when it functions as intended. Programming is relatively easy and it seems consistent. However after a few weeks I started getting an ER- code. The device emits a loud tone when this happens and ceases to function. After inspecting the device I found nothing amiss with the setup. After an hour or so the unit clicked back on and resumed normal function. This pattern continued and increased in regularity resulting in semi-regular humidity dips and as a result the plants suffered greatly. This behavior became more and more regular as use of the device continued. Eventually the ER- would not clear and the device was removed from use. Upon further inspection and disassembly of the sensor whip it appears as though one of the leads was not seated all of the way into the connector, resulting a short and the ER code. After reseating the lead the device was tested and functioned per normal. That sensor whip contains a strain reduction loop which the sensor cable wraps around prior to reaching the sensor. While this is a nice feature... it results in the leads being almost taught within the sensor enclosure and likely was the root of the failure I experienced.

Easy to use after the You Tube video on it. Don’t know what I’d do without it. Works perfect

I use it to maintain humidity levels at 95% in a mushroom fruiting tent. Its a game changer. Previously I had used a number of humidity meters made by other companies. All of them malfunctioned at high humidity levels. The inkbird maintained 95% levels well. I realized that that could be done without condensation in the tent.

There are two ways to control humidity and this device controls both. I used it to turn humidifiers on when the humidity dropped too low. This unit can also turn on ventilation when humidity gets too high. (But I didnt use that feature.) Makes humidity control easy!

I bought this to cycle my console humidifier because the onboard humidistat failed. I used the calibration to roughly calibrate the unit. I keep gauges throughout the house so the actual set point is a reference setting but it is still real close in the end. Keeps the humidity within 1% to 2% in my application and environment. I purchased a second for my dehumidifier in the basement to be used in the summer months. If these continue to work without failure I will upgrade to 5 stars because they do work.

Update: a couple days later and now it just beeps and says err and wont take any readings Out of box my unit is reading 75-85 humidity in my house. Tried a table salt calibration test and it was reading 86-90 (should be 75). Seems like it is atleast 15-20 percent off and fluctuates pretty wildy. Calibration only compensates up to 10 percent +/-. Looks like the actual sensor has a plug connector so it should be easy to be replace but I havnt been able to pry open the plastic casing that protects it. Contacted the amazon product support and they didnt understand the issue but offered to help me return it.

great product, a bit hard to setup all the features, but once you do it is fantastic.

Ball pythons need a decently high humidity, but nothing insane like a chameleon. We use a glass terrarium with some vent holes, so keeping the desired humidity was a daily struggle. After a quick setup, this now keeps his terrarium at the perfect humidity levels. The directions seemed vague and confusing at first. But we did not need most of the settings and then realized we just needed to set basic humidity levels.

I use this to control the humidity in my snake tank after my girlfriend accidentally set the humidity too high and I came home to a very wet tank!! :O The accuracy seems very good as I have 3 other humidity sensors in the tank and the read almost exactly what this device reads. I only use it to turn on and off the humidifier, and I do not have a dehumidifier device attached. It works great. I expect that this device will cause the life of my humidifier to be significantly less because it is turning on and off, BUT this is expected with electronics. The more you turn on and off things, the less life they have. None the less, my snakes health is most important so I love this so I know her humidity is perfect. I will update if the product dies but so far it is running great!
