Hi guys,
I am using two HG-C 1100 measurement sensor for measuring the width of the metal. In the top of the sensor I will be having the measurement value. The sensor is capable of measuring the dimensions from -35mm to 35mm.
So I am using the formula:
If I use this code, I will get the proper width of the metal. But when I place the metal in between the sensor, I am getting the exact width in the serial monitor. But at the top of the sensors the values are different.
I don't why the analog values are different on the serial monitor and the top of the sensors. But the output of the sensor is perfect in the serial monitor.
Can anyone help me with this?

While teaching the sensor also, I get +35.00 and -34.98. But when I place the sensor, I get +35.70 and -35.70. Why is this error occurs in the sensor?
How can I rectify the errors?
Is this errors adding to my other values?
Kindly help me,.
@manoj_maniyan no-one here is familiar with this sensor. I have read parts of the document you attached. It is more like a sales brochure or a user instruction manual than a data sheet. The document focuses on the sensor's display and controls. There is no detailed description in the document about the analog output and how to interpret it's value.
It might be more accurate to use the Arduino's interval voltage reference, which is 1.1V for Uno. It will be necessary to use a voltage divider to reduce the signal from the sensor down to below 1.1V.
But when I add the arduino code and see in the serial monitor, the values aren't as like the top of the sensor. if the first sensor is -17.5, it is taking as -17.78. if the second sensor is -21.5, it is taking as -21.12.
I have to know why there is a difference.
But the metal I place between the sensor gives me the proper output.

RosettaCNC Board A is an ETHERNET motion controller that manages up to 4 interpolated axes. The ETHERNET port (instead of USB) ensures fast and secure transmission thanks to the protocol and at the e galvanic insulation with the PC connection.
Does not require the use of external electronic parts or protectors. The power supply is integrated and protected, The inputs and outputs are equipped with opto-insulator that guarantee, together with the metal container, high resistance to electromagnetic interference. The outputs are protected from short circuits and allow you to directly connect inductive loads (relays or solenoid valves), without having to add external components.
The control outputs of STEP/DIR type are generated by a powerful FPGA That allows to reach operating frequencies of 2MHz (with stable duty cycle at 50%) making it possible to use both step-by-step drives and servo drives.
Rosetta CNC Board commands the axes using a look ahead that allows you to achieve high interpolation speeds.
The product can possibly be equipped with a handwheel, supplied already complete with connector, alternatively, it makes available inputs for the jog connection joystick type and other useful control signals.
Rosetta CNC Board is equipped with removable spring connectors to allow quick wiring, highly reliable and free to vibrations.
RosettaCNC Board it's powered in low voltage, 24VDC, the I/O line are opto-insulated and the PC connection is galvanically isolated, therefore the device is not a direct threat to the health and life of the user.
The design of a complete control system (electric panel), should draw attention to different aspects of, so that the whole machine system does not become a danger during the use.
It's good practice to always use NC contacts for the limit switches and for the emergency button So that a wiring error or a wire disconnection always lead to machine shutdown.
Special attention must be paid to the emergency stop circuit: The control system must be designed in such a way the that when you press the button for emergency stop, the machine immediately interrupts the movement of all axes. You should also consider the possibility of failure of particular components of the system, as the main controller, or the axes control units.
In the below picture, is used a safety device Pilz model PNOZ X7. The emergency button, and possibly other alarm signals (safety barriers, crankcase opening, etc.) must be connected to the input circuits. An output must be connected to the EST1 input of RosettaCNC Board And in series also the drive ok outputs. The other exit of the safety module must be used to stop power to drives.
S1 is the Restore button.
S2 is the stop button in emergency.
The wiring must be carried out by specialized personnel and provided with appropriate anti-static measures.
Before handling the instrument, remove voltage and all parts connected to it.
To ensure with the CE compliance, The supply voltage must have a galvanic insulation of at least 1500 Vac.
If stepper motor drivers are used, for a satisfactory user experience that minimizes vibrations and resonances, it is recommended to set at least 32 or 64 microsteps. However, the appropriate value must always be chosen considering the maximum frequency set and the characteristics of the driver.
In the following example we see a wiring diagram of three stepper drives. The HOME switches are also used as a limit for the direction of movement where the homing procedure is executed. For the other direction, uses three NC switches in series and connected with the LIM input.
In this case the correct setting of the inputs in the configuration panel will be:
If RosettaCNC Board controls also the spindle rotation speed then you must connect the analog output 010V to the analog input of the drive. In the maximum speed parameter, you must set the the speed reached by the drive to the maximum voltage of 10V.
Starting from software version 1.9.4 it is possible to connect the IQ023 accessory to the control PC.
The use of this accessory must be enabled in the board settings.
The resources of the accessory are mapped as follows:
