3.6 Wireless Data Transfer
We transfer the control signals in our project using wires from PC to the PIC microcontroller.
To advance the project we use the radio frequency transmitter and receiver module for a wireless control transfer signals as another options.
The Compact FM Hybrid transmitter and receiver Modules are used in this project to receiving a signal data at up to 9.67kbps of the state of the transmitter with rang up to 250 m with CMOS/TTL Compatible Output, offers low current consumption , which uses no adjustable components ,and requires No radio license to operate . The transmitter is attached to the serial port on the PC to send data on the 433.92 MHz carrier to the motion control subsystem.
