Microwaves. They give off microwaves!
Also light bulbs (visible EM), heating coils (infra-red EM), and ovens (infra-red EM).
Also radios and TVs receive radio waves, garage-door openers generate and
transmit radio waves, blow-driers irradiate the air passing through them with
infrared (heat) waves, smart and dumb cellphones all send and receive radio
waves, laptops on wireless home wi-fi send and receive radio waves, and their
screens generate and radiate visible light waves which make it a lot easier for
us to see what they're computing.
Radio waves, sounds waves arn't electromagnetic waves.
Solar flares emit electromagnetic waves.The electromagnetic wave interrupted cellular phone communications.Satellites can be damaged by electromagnetic waves.

WiFi uses electromagnetic waves in the microwave band, around 2.4 GHz or 5 GHz.
There are two types of smoke detectors:Alpha particle - these do not use electromagnetic wavesPhotoelectric - these use a beam of either visible lightor near infrared electromagnetic waves
