Smart Thermostats

Wi-Fi–enabled smart thermostats showcase a range of circuit protection and sensing solutions Littelfuse can deliver. Our ESD protection devices prevent damage from human–machine interactions with the unit or a smartphone. Our overcurrent, overvoltage, and thermal protection devices prevent shorts and overloads. And our diodes, solid state relays, and temperature sensors ensure efficient operation.
