I have sensor which gives Analogue output 2-10v, Now I want to operate two Relays (by RAJEEV)

I have sensor which gives Analogue output 2-10v, Now I want to operate two Relays.
First relay I want to operate with 5v output and second relay should operate when my sensor give 9v output.

thanks in advance.

Analog input goes from 0-1024 (1000) for input signal 0-5V.

First You have to divide input signal by two, and then use analog input.

0-10V input is 0-1000
5V is 500
9V is 900

I hope You understand.

Dear Mr. Boris,

Thank you very much for your reply and I really appreciate for your help.

I had seen Samples files of LDMICRO programs. I was little confuse, now its clear.

Can you give any example file related to my program if possible.

Thanks

Microcontroller only works with input 5V, first you need a voltage divider.
Its sensors is 0-10v should divided by /2 through a voltage divider. Voltage divider are made with resistors and not with programming.

Dear Mr. Rafael,

Thanks for your reply.

in interfacing You have:
"Measure a DC Voltage Between 0 V and 15 V"
instead R1-20k use 10k

Check in simulation to see how it works

You can display value on LCD if You want.

Analog sensor (1-5v) display fluctuates (by Mukesh Pandey)

I have sensor which gives Analog output 1-5v. But my display fluctuates. please check the program & suggest any modifications. do I need an averaging circuit? if yes please suggest how to perform. if we have any instructions for the same in Ldmicro. I congratulate & thankful to you for launching new version.

Thanking you for your precious guidance

Is there any way to use Vref- & Vref+ pins to alter analog input reference voltage by using move instruction (by Mukesh )

Is there any way to use Vref- & Vref+ pins to alter analog input reference voltage by using move instruction in LD micro. Please check if this program will change the reference voltage of analog input.
Thanks & Regards
