Sensor-transceivers-pic 16f877a-gsm

[aadebola5]

please i need a guide on how to interface a pir sensor with a rf315MHz transmitter, and how to interface the rf315MHz receiver with the PIC16F877A, and how to interface the PIC with my gsm module (SM5100B-D)..i dont know if a PIC is needed with the transmitter to send the data to d receiver.. please i dont really know much on this am kind of new to these...and i have been reading some materialls on how to intterface and program this project but dey are not really helping..lease i need help from y guys...thanks

do one thing first start to study about that sensor,tx,rx,and microcontroller (hardwere,softwere)k then u ll get some knowledge then u tried to do your self (just imagine and do it k) then u ask others for help bcz i faced same problem...

 

[aadebola5]

please i need assistance on these codes am goin to paste now, the function of the code is to switch on the LED wirelessly if a motion us detected i used CCS to write the code but it is givin me errors..please i need help..thanks

the transmitting side
