摘要:
A monitoring apparatus includes a detecting unit with a humidity sensor configured to sense humidity and output a corresponding humidity signal. A controller is configured to receive the humidity signal and output a ventilation control signal when the humidity signal exceeds a preset humidity threshold. A first driving unit is configured to receive the ventilation control signal and drive a ventilation device. The monitoring apparatus detects a humidity condition in an environment with a humidity sensor. When the humidity signal exceeds the preset humidity threshold, such as when the humidity is high, a ventilation control signal is output by the controller to control the first driving unit to drive the ventilation device. When the humidity is low the ventilation device is turned off.

A switch assembly includes a switch cover and a switch base. The switch cover fixedly couples to the switch base with engagement protrusions integrally defined in the switch cover and corresponding apertures defined within the switch base without fasteners or requiring tools. From a disassembled configuration, the cover couples to the switch base by aligning cover protrusions with corresponding base apertures, pressing the cover against the base, sliding the cover in a first engagement direction, and locking the cover protrusions into the apertures by applying a threshold level of engagement force in an engagement direction. From an assembled configuration, the cover de-couples from the switch base by applying a threshold level of disengagement force in disengagement direction oppositely oriented with respect to the engagement direction, thereby unlocking the cover protrusions from the base apertures.

A system for controlling a power input to a load includes a gate action monitor configured to transmit a door activation signal corresponding to an opening or closing of an access way to an enclosed space, a double signal sensor configured to transmit an occupancy signal corresponding to a detected occupancy of the enclosed space and a temperature signal corresponding to a detected temperature of the enclosed space, and a controlled load switch configured to detect one or more of the door activation signal, occupancy signal and temperature signal, and enable or disable the power input to the load.

摘要:
A switch control circuit and a switch control system includes a plurality of parallel-connected signal processing units. A first voltage signal and second voltage signal control turning-on and turning-off of the first controllable switch, and converting the first voltage signal into a third voltage signal; and the third voltage signal being connected with the first port of the controller; and the controller, configured to send a switch control instruction to a to-be-controlled terminal based on the third voltage signal. This circuit converts a electrical signal of a high voltage in strong electricity into a stable electrical signal of a low voltage in weak electricity, implements multiplex switch control in conjunction with the controller, and only processes voltage signals in the whole circuit, thereby avoiding processing signals of a plurality of types, and guaranteeing the reliability of the multiplex switch control.
