IC2262/2272 4 Channel 315MHZ 4 Key Wireless Remote Control Kits

Features: 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. Specifications: Remote control Operating voltage: DC12V Operating Current: 10mA @ 12V Radiated power: 10mw @ 12V Modulation mode: ASK (Amplitude Modulation) Transmitting frequency: 315MHZ Transmission distance :50-100M (Open field, the receiver sensitivity of -100dbm) Encoder types: fixed code With 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
