4 Channel Wireless Four button remote control Transmitter Receiver Module with Non-Locking mode can be composed of a fixed code four radio receiver circuits, remote control of four four-bit data output code corresponding to the module, you can easily make up a wireless remote control receiver circuit, the products are widely applied in the majority home electronics enthusiasts, industrial remote control electronic product design and development, can be very good as a single-chip signal input source, especially for students and colleges electronic circuit design, graduate design of the remote control circuit portion.
With super-regenerative receiver module can decode four remote control and transmitter consisting of four radio receiver circuit. The module is widely used in the majority of electronic enthusiasts for domestic, industrial remote control electronic product design and development can be very good as a single-chip signal input source, especially for students and colleges electronic circuit design, the graduate design of the remote control circuit section. Receiver module self-locking, non-locking, interlocking three models, please describe in the remarks before ordering.
- There are four buttons on the remote control and respectively correspond to the four data bits to the receiving board output pin D0, D1, D2, and D3.
- Press the buttons to transmit signals, the corresponding data bit is output high.
How it Works:
When a key is pressed, the IC is connected to power supply battery and it starts transmitting packets at 433 Mhz frequency consisting of its ID and Data byte which indicates which key was pressed. This information is used in remote control applications.
Each transmitter has pre-programmed unique ID set during manufacturing and cannot be changed. The receiver board usually stores the transmitter ID in its memory before so receiver only responds to known transmitter IDs for secure applications.
The RF part inside remote is SAW based 433 Mhz transmitter, which can be received by any 433 Mhz type ASK RF Receiver followed by decoder chip.
These remote comes in different operating Mode:
Non-locking Mode, Self-Locking Mode, and? Interlocking Mode
Output also has known jog output data pin output level is instantaneous and the transmitter and whether transmission corresponds, can be used to control similar to jogging, a remote control signal data pin is high, the signal disappears when the remote data foot immediately restored to the low level, for applications such as electric doors, electric door locks, and SCM docking requires only a high level of circuit and other circuits and so on.
Here Data output pin enables the trigger to flip operating logic, and data can be kept as long as the successful reception of the corresponding level state change until the next time the remote data changes. Self-locking independent of each other four, four simultaneous remote control, such as lighting control and the like.
The?Output is any way the road will be able to receive the signal remains high state corresponding received data in any other way is the return to the original state, only four interlocking turned all the way, practical applications such as electric fans position switch circuit.
