2 Decoding receiver board

• 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.
• Size: 6.6*22*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 of. Press the buttons transmit signals, the corresponding data bit is output high.
