STC-3028 AC110~230V All-Purpose Temperature and Humidity Controller with Dual Displays and Dual Relay Outputs(Shipping with 2 Sensors)

Used to control a dorm fridge to make a cheese cave. Easy to use and did the job

The product seems legit, even though I haven't used it yet. But, it does not come with the receptacles built in. This will require you to cut the power cords and hook the whites(neutrals) together then land the blacks(hots) under the relay lugs for the temp or humidity(whichever you are controlling. The reviews say that this board does ok in the humidity, but having been an industrial maintenance electrician for 18 years, I know that it will lead to issues with corrosion and eventually short out. I will be installing mine in a box outside of my tent.

Works in extreme humidity, I used mine in a modified monotub with humidity 85% to 100%

This unit is for temperature and humidity control. If you look at the plugs at the end of each sensor you will see that they are small plugs. The plugs where they plug into are different. The temperature will fit into the plug but the humidity will not fit. You need to cut the wires in order to get them to fit but there is no wire schematic to show which wires are which. This is just more junk from China

This item was bad out of the box, would not recommend this product to anyone

I don't know if this thing works or not. There aren't any directions that explain how to connect the sensors. I'm an electrical engineer and I gave up and sent it back.
