Hi Alain,

For the answer of your question;

1.Yes,i have the Comparators module aboard the 4550 which is this 4550 have analog comparators on PORTA and another port.I will attach the picture of PIC18F4550.These 3 sensors were connected through PortA0 to PortA2.

2. Actually i used TRISA.1=1 just for test one of my sensor either it is function or not.I used the TRISA=1 so that all my 3 sensors active but the problem was from the instruction of ADCON1.there seems like the sensors not funtion when i used only 1 ADCON1 to combine all of 3 sensors.
