I opened this thread to explore alternatives for laser rangefinder models. That is, a portable measurement sensor that calculates the distance between the observer and a target object. My specific use case involves detecting black objects (briquettes used for electrode paste formation ).
However, when using it, I noticed that the sensor struggles to take measurements beyond 15m. I need a sensor that ensures minimum measurements of 15m, considering that the target is the surface of a layer of briquettes.
I would like to know if you could recommend any reliable manufacturer models that you have tested under the conditions mentioned above. The communication interface could be I2C, USART, Serial, RS485, among others, and preferably with a protection rating suitable for operation in industrial environments.
I would like to highlight that this BOSCH model operates through manual reading, requiring the user to press a button for the measurement to be performed. In my case, I want the start and end of the measurement to be carried out via digital communication.
The target objects (briquettes) are not very large when we talk about a single unit, which does not exceed dimensions of 10cm x 10cm. They can vary within this range. The issue is that I don’t need to measure just one unit, but rather a surface or layer of multiple objects of this type. The accuracy I require can vary around ±10cm, as high precision is not necessary. However, the sensor must be capable of measuring the dark object at distances of up to 15m.
Regarding the price, I was expecting to spend up to 300 USD, but if you have suggestions that are more expensive, feel free to present them to us.
I purchased a unit of the TF03-100 UART model from Benewake for testing. It should arrive next week, and I plan to evaluate its performance for my application.
Thank you in advance for your collaboration, and any guidance is greatly appreciated.
