To provide a remote controller maintaining battery life for long time use, and hygienically and conveniently used by non-contact operation.
A toilet seat device includes a body 200 installed on a toilet bowl 110, and a remote controller 400 using the battery 450 as a power source, the remote controller 400 includes an illuminance sensor 440, and a control unit 500 for detecting the operation movement of a user in a non-contact manner by fluctuation of detection voltage of the illuminance sensor 440, the control unit 500 includes a sensitivity adjusting section 550 for correcting the detection sensitivity of the illuminance sensor 440, the sensitivity adjusting section 550 switches a plurality of resistors to adjust the detection voltage of the illuminance sensor 440. Accordingly, the illuminance sensor 440 dedicated to detect the change of ambient illuminance does not need to be installed, the illuminance sensor 440 maintains the battery life, and the toilet seat device highly saves energy, is precisely operated, and hygienically and conveniently used.
