A remote control device having capacitive touch controls may be configured to enter a sleep state (or mode). For example, the remote control device may be configured to enter the sleep state upon expiration of an interval of time since a most recent button press. The remote control may be configured to awaken from the sleep state when one or more portions of a housing of the remote control are deflected, for example, when a user grasps the remote control to actuate one or more of the capacitive touch controls. For example, the remote control device may include a switch. The switch may include a carbon structure that may be configured to contact an open circuit pad on a circuit board to close the corresponding circuit when the housing is deflected and awaken the remote control device from the sleep state.

Provided is a communication system for an air conditioner including a housing and a control board accommodated in the housing. The communication system includes: a communication conversion unit accommodated in the housing and configured to acquire a required electric signal from the control board and to convert the electric signal into a digital signal for wire transmission; a cable having a first end connected to the communication conversion unit, the cable being drawn out of the housing to outside; and an antenna unit connected to a second end of the cable located outside the housing, the antenna unit being configured to establish wireless communication with a base station.

A sensor device includes an oscillator element that is suppliable with a trigger signal, an activation and deactivation of at least one sensor element of the sensor device being initiatable with the aid of the trigger signal and an activation element, and at least one piece of sensor data of the at least one sensor element being storable in a register after the at least one sensor element is activated; and an interface connected to the register and via which the piece of sensor data is transmittable to the control device.

An exemplary method includes operating an access control device in a standalone mode, which involves controlling a locked/unlocked state of the access control device locally, and operating a wireless transceiver of the access control device in a lower-power state in which the wireless transceiver is operable to receive a lockdown signal from an external device. The method further includes operating the access control device in a networked lockdown mode in response to receiving the lockdown signal from the external device. Operating the access control device in the networked lockdown mode involves placing the access control device in a locked state, establishing a wireless communication connection with the external device via the wireless transceiver while operating the wireless transceiver in a higher-power state.
