6.CR2032The button battery（Seat），Require Shunfeng Express not to generate batteries。

7.Wake-up distance1-6m

8.standby power 15ua。

Operation process：

1.Base station board mountedCR2032Battery，The sending board is connected to the computer by an Android cell phone data line（Or plug inDC12VPower Supply）。

2.Receiving boardThe ideal position of the antenna is parallel to the antenna at the receiving end.（The furthest distance）。

3.Turn on the power switch，Power Connection of Base Station Board，Base station board starts sending wake-up signal（Base station board433The waiting time for the data returned by the radio frequency prepares to receive the remote control board is4SNo data relay buzzer on left or right），Send outLFWake up signalStudyIndicator lights on once，After receiving the wake-up signal, the remote control boardSTCSingle Chip Microcomputer Wakes Up，Simultaneous adoption433MSingle-chip Microcomputer Simulation of Radio Frequency Transmitting ModuleHCS300/301 66bitFixed code（You can also customize or scroll codes）Continuous data transmission3second，The sending board decodes the received data，Open relay after validation、A buzzer rings.1-3sound、StudyIndicator light。

High frequency data to be received（wait for4S）。

5.Explain：On Receiving Board Waiting4SReasons for Rear Base Station Board Not Acting：

1）.Receiver is far away（The board is a test board.，The actual effect of high frequency remote controller is poor.，Non-commercial grade for testing only use，Nonfeasance Assessment of the Performance of the Test Board，Of course, the low-frequency correlation test conforms to the project application and the actual scope of use.， Attention should be paid to the matching of antenna resonant capacitors，To further enhanceLFEffect，AS3933Internal32PFStep by step transferHarmonic Vibration capacitance）。

2）.Is the Remote Controller Learned，Re-study。

6.Control rough flow：The remote control board is awakened--->Post-wake analog coding433MSend out--->Sending board433MReceived signal--->base station Check whether received data is legitimate on board---->Turn on Relay Output、Indicator light、Buzzer。

7.Detailed instructions for operation。Please ask for instructions，It's a little different from the above.，But roughly the same way.。

Shipping list：
