I am looking for a non-contact measuring device that will allow me to measure the distance away from a piece of wood with a range of 6 inches down to one half of an inch. I need an accuracy of approximately 1/32 of an inch. If possible, the unit should be able to fit through a half-inch diameter hole.
Hi,
You can take a look at our Infrared Range Finders or our Ultrasonic Range Finders.
This 30cm Infrared Distance Sensor might interest you.
If I use the Sharp GP2Y0A51SK0F, which seems to have the perfect range I’m looking for,how does it output the information? Do you have a small screen to list the distance?
The Sharp GP2Y0A51SK0F outputs analog voltage depending on the distance to the reflective object.
Here is the analog voltage output vs the distance graphe in the Sharp GP2Y0A51SK0F datasheet.
Regards,
Thanks for the data sheet but I am new at all this. What I need is a sensor that will detect the distance of a piece of wood that is between about 1/2" - 6" away, send that signal to a screen and display it in decimal or better yet, fractions. I would also like the screen to be able to receive a second input from a second sensor and give the difference between the two.
Are there off the self items that can so this?
In addition to the IR Sensor, you will also need a microcontroller that will receive the voltage output from the distance sensor in its ADC and translate it to distance then send it to an LCD display.
You can use for example an Arduino UNO microcontroller board and an LCD Shield for Arduino.
