A customized HCS301 remote control for houses is a radio transmitter using Amplitude Shift Keying (ASK) technology. This technique is especially useful when modulating and demodulating digital data.
When a button on the customized HCS301 remote control is pressed, the remote will send a signal to control the state of the relay in the receiver. The signal is modulated by baseband digital data into the form of a radio frequency carrier.
A customized HCS301 remote control for houses converts baseband digital data into a radio frequency signal and transmits it through the antenna. The receiver of the customized HCS301 remote control will receive the signal and restore the baseband digital signal through the demodulation process. Then, the receiver controls the state of the relay according to the instruction to perform the corresponding operation.
In addition, the customized HCS301 remote control for houses adopts some security methods to ensure the confidentiality of communication. The remote control processes the data using an encryption algorithm and sends it to the receiver. The decoder of the customized HCS301 remote control decodes the encrypted data at the receiver side. This makes communications inaccessible to unauthorized users.
