hi all, hi admin i hope you and us to success in this good forum

my problem is to make a proper wireless communication to send data (temprature sensor reading data for example) using RF transmitter and receiver (RXS 433, TXD 433).

the transmiter is located on the mobile robot, the receiver (RXS 433) is conmected to a PC through a serial or parallel port and special terminal software will be used to read the data from the RF receiver throgh the PC port

r u have any idea or suggestions about this problem
thanks much
i am waiting

You will probably need a micro-processor. Did you have one in mind like an AVR or PIC or something. Then the MCU reads the tempurature, converts it and sends it to the TX chip.

Then you will read it in from the RX chip (probably connected to serial port on PC if you are using a terminal program). Or you can read it directly from printer port if RX chip connected to parallel port.

The rest is software, conversion and timing.

If you have only one sensor that you want to read, you MIGHT be able to configure your RX/TX chips to send "live" and eliminate the MCU but the data from temp sensor would probably need to be digitized first, something that most modern MCUs have built-in. Then your PC would poll port for readings.

More details would help.
