Another type of thermal switch is a PTC (Positive Temperature Coefficient) thermistor; these thermistors have a "cutting off" temperature at which the resistance suddenly rises rapidly, limiting the current through the circuit. When used in conjunction with a thermistor relay, the PTC will switch off an electrical system at a desired temperature.
Most modern fan heaters have a power setting to determine power output. Some also have a thermostat which switches off heating when the desired ambient temperature is reached. They do not maintain perfect room temperature control, since: the thermostat is usually attached to the body of the heater, and senses temperature there.
A humidistat or hygrostat is an electronic device analogous to a thermostat but which responds to relative humidity, not temperature. A typical humidistat is usually included with portable humidifiers or dehumidifiers. It can also be included with combined air cleaner or humidifier units to control a home's humidity level or any other indoor ...
Smart thermostat, doorbell, appliances, speakers. I read about a guy who couldn’t turn on his ceiling fan when AWS went down. Seriously- who needs a cloud enabled ceiling fan.
A fan controller with LEDs indicating fan status and potentiometers and switches to control fan speeds Another method, popular with PC hardware enthusiasts, is the manual fan speed controller. They can be mounted in an expansion slot or a 5.25" or 3.5" drive bay or come built into a computer's case.

A thermostat exerts control by switching heating or cooling devices on or off, or by regulating the flow of a heat transfer fluid as needed, to maintain the correct temperature. A thermostat can often be the main control unit for a heating or cooling system, in applications ranging from ambient air control to automotive coolant control.
The study, which followed healthy older adults for 5 years, found that antibiotic use was not associated with an increased risk of cognitive impairment and dementia.
