Inkbird Humidity Controller Probe Used for IHC200 Humidistat Sensor

My sensor in the controller didnt work correctly so I bought this one to replace it.Now it works fine.Two points to pay attention1. the wire colors might be different to the controller. In this case open the old and new sensor and try to match the order in the socket, for example if the order from left to right in old sensor is red black white blue and in new sensor blue green black white, then connect the red wire from controller to the blue wire from the new sensor, and so one …2 I’m using this for humidity in greenhouse with diggers. If you are doing the same , protect the sensor from the fog. see the right one in attached picture.

As the other reviews have said this ad is one of the most misleading listings on Amazon. This sure isn't what I expected from a company like InkBird. I have been using InkBird products for years in all of my tanks and reptile enclosures. I have found their products to be very accurate and very reliable which is essential for the animals that I keep in large numbers. By looking at the photos provided it makes you believe that you are receiving an entirely new probe with the cable it is attached to and you simply unplug the bad one and plug in the new probe. This isn't the case at all, what you receive is just the sensor itself, not the 12ft cable in the photos. They instruct you to cut the old probe cable and splice this one in. Don't do this, if this is being placed in a humid environment splicing wires should always be avoided. It make work for a while but in time corrosion will set in and you will end up with another bad sensor. Yes, you can use Marine Grade Connectors, Dielectric Grease and quality Electrical Tape that will prevent the corrosion but the average person will not have these and know how to do the splice properly, besides it being unsightly when finished. A far better option is to be very careful and pry the enclosure open, unplug the actual sensor from the housing and replace it with the new one. Before installing the sensor apply some Dielectric Grease to the connector which will prevent moisture from causing the corrosion that destroyed the original. I am shocked that a company like InkBird would sell a product that is prone to certain failure when 2 cents worth of grease would prevent the failure in the first place and then sell a replacement probe that makes the customer believe they are buying something that they will not receive. Everyone makes mistakes, but they have clearly known about this issue for quite some time judging by the reviews. Instead of changing the photos in the ad and changing the written description that makes it clear what their customer is purchasing they chose instead to do nothing about it, and therefore they are no longer my recommended brand to go with for all my climate control needs. I sure never thought that I would ever write a review like this for any product sold by INKBIRD.

This come just like the picture with 4 wires sticking out of sensor which means that the housing doesn't clamp on the wires because the outer insulation is not there. I took apart the old sensor using a razor knife to gently pry apart housing but still managed to crack it getting it apart. The old wires actually have a crimp fitting on the end that plugs into the unit (4 of these). Using hemostats was able to unplug them hoping to reuse all the old wire. Thought I should try plugging them back in before trying to disassemble new unit. They didn't want to plug back in very well so at this point just decided to leave new unit as is and not disassemble and just splice wires. Wires are tiny and hard to strip but doable. Soldered connections and used shrink tubing and electrical tape to finish the job. All worked out and replacement is working fine. From what I have read these sensors don't last that long and glad they sell the part for 15 bucks instead of having to replace the whole controller for 42.99. Would be nice if they had the sensors set up with an outside plug so replacing would just amount to unplugging old one and plugging in new one. The inkbird IHC-200 is a must have for a grow room and I have a complete spare unit in case of a malfunction. Will probably buy another sensor to have on hand in case they decide to quit selling replacement probes.

Adding this review cause there's no instructions for this kind of replacement, and the product works perfectly when installed properly.What you'll need is some kind of flat head mini screwdriver like for sunglasses or similar, and needle nose pliers. The plastic cover on the humidity sensor has one tab in each corner (see my picture). To take off the cover, you need to wedge the flat head screwdriver in the middle of of the edge on one side between the tabs, and gently pry until that edge comes free - you may have to work each corner.Once one edge is free, then simply continue opening the cover in the direction opposite of the starting edge. It may take a little force but should pop off if you do it carefully. Repeat the process for the new unit to expose the wirse in each.When both covers are off, use the needle nose pliers to gently remove the plug from both units (don't lose track of which is which!). Plug the wires into the new unin then snap on the cover and you're good to go!Once I installed the new unit the humidity levels were way more responsive. Definitely worth the price.
