RF 4 CHANNEL REMOTE KIT
Pin Vcc – Positive power, 5VDC
Pin GND – Ground .
Pin D0 to D3 – These are the output pins which you should connect to device you like to control.
Pin VT – Valid RF signal indicator pin. When receiver receives valid signal this pin will goes high.
IC2272 315MHz 4 Channel Wireless RF Remote Control Transmitter Receiver Module
Operating voltage: DC 12V (27A / 12V battery x 1)
Operating current: 10mA at 12V
Radiated power: 10mW at 12V
Transmission distance: 50m -
Transmitting frequency: 315MHZ
Modulation mode: ASK (Amplitude Modulation)
Encoder types: fixed code
Operating voltage: DC 5V
Receiver sensitivity is -
Leg 7 bits: VT, D3, D2, D1, D0, +5V and GND
VT is a valid signal high output pin upon receiving a valid signal, the pin output high, may also drive the relay
Size: 6.6 x 22 x 41mm
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 transmit signals, the corresponding data bit is output high.
This Simple RF transmitter and receiver is the easiest way possible to add wireless control, painlessly! There's no programming, configuring or addressing -
When button A is pressed, it activates the first pin on RF module (Receiver) -
The RF module make it easy to control your project once its in an enclosure or from across the room, but there are some things to watch out for.
• 1st is that they do not have 'addressing' -
• 2nd is that there's no error checking or bi-
• 3rd, there are a few different types of receivers and each one looks identical but they're act differently!
This is T4 toggle type acts like an alternating toggle switch -
The M4 momentary type acts like a push button -
From test that we did, the control is good within 8 meteres with line of sight. Also please use battery instead of adapter. We notice using adapter (AC to DC) will greatly decrease the range.
