433MHz Remote Control 4 Ch Transmitter with Receiver PCB
 
 
Product Information
 
Remote control transmitter
 
This is a 4 Button 433MHz Transmitter with Extending Antenna.
1.Operating voltage: DC12V (27A/12V battery x1) (NOT included)
2.Operating Current: 10mA @ 12V
3.Radiated power: 10mw @ 12V
4.Modulation mode: ASK (Amplitude Modulation)
5.Transmitting frequency: 433MHZ
6.Transmission distance :50-100M (Open field, the receiver sensitivity of -100dbm)
7.Encoder types: fixed code (Can be changed!!)
 
 
Decoding receiver board
 
1.The operating voltage DC5V, receiver sensitivity is-98db. Leg 7 bits, respectively, VT, D3, D2, D1, D0, the +5 V and GND.
VT is a valid signal high output pin Upon receiving a valid signal, the pin output high, may also drive the relay.
Please note: code can be changed! Obviously must be set the same as the transmitter.
Note: There is an Antenna Fixed already to the Receiver PCB
2.Size: 6.6*22*41mm
 
There are four buttons on the remote control, and respectively correspond to the four data bits on the receiving board output pin D0, D1, D2, and D3.
Press the buttons transmit signal, the corresponding data bit is output high. Can drive a relay.
