This makes them suitable for remote control applications, as in where you need to control some machines or robots without getting in touch with them (may be due to various reasons like safety, etc). Now depending upon the type of application, the RF module is chosen. For short range wireless control applications, an RF Transmitter-Receiver Module of frequency 315 MHz is the most suitable type. This RF modules are works with PT2262(encoder) and PT2272(decoder) as remote control.

Specification: Frequency: 315Mhz Modulation: ASK Transmitter input voltage: 3-12V Transmitter(RF-TX-315) and Receiver(RF-RX-315) Range in open space(Standard Conditions) : 100 Meters PT2262 Is a remote control encoder paired with PT2272 utilizing CMOS Technology. It encodes data and address pins into a serial coded waveform suitable for or IR modulation. PT2262 has a maximum of 12 bits of tri-state address pins providing to 531,441 (or 312) address codes; thereby, drastically reducing any code collision and unauthorized code scanning possibilities. PT2272 Remote Control Decoder PT2272 is a remote control decoder paired with PT2262 utilizing CMOS Technology. It has 12 bits of tri-state address pins providing a maximum of 531,441 (or 312) address codes; thereby, drastically reducing any code collision and unauthorized code scanning possibilities. This IC has Latch or Momentary output type. Features: CMOS Technology Low Power Consumption Very High Noise Immunity Up to 12 Tri-State Code Address Pins Up to 6 Data Pins Wide Range of Operating Voltage: 4v-15V Single Resistor Oscillator
