Anyone with a poorly ventilated bathroom knows the unpleasant and damp feeling after taking a shower, not to mention the creeping growth of mold and mildew on surfaces. It can be a particular problem in a one-bathroom home with many users. A humidity sensor and fan control is a device that solves the problem and detects changes in humidity. It’s designed to control any bath fan and creates an atmosphere and environment for everyone to enjoy, no matter how often the room is used.
To install the device an electrician will charge $115, which includes the labor and material. If you have experience with electrical projects and tools, you can buy the device for $40, install it and save 65 percent. You’ll need a bladed and Phillips head screwdrivers, wire cutters, pliers, voltage tester, wire nuts and electrical tape. Read the manufacturer’s directions thoroughly before you begin. Don’t forget to turn off the source of power at the electric panel.
