Erha sensor's color recognition is still very accurate and fast. We will perform multiple color recognition this time. First, we need to set it to "learn multiple", which is the same as the setting for face recognition.

(1) After we turn on the Erha sensor, turn the "Function Key" and select "Color Recognition".

(2) Press and hold the “Function Button” to enter the secondary menu parameter setting interface of the color recognition function.

(3) Toggle the "Function Button", select "Learn Multiple", and then short press the "Function Button". The progress bar turns blue. Short press the "Function Button" again to confirm the parameter.

After the settings are completed, you can perform color recognition. When Erha recognizes the color, a white selection box will be displayed. Then press the learning button to recognize the color.

Object recognition and color recognition are similar, and the settings are the same. After the settings are completed, any object can be recognized, but... I found that Erha failed to recognize objects. It seems that it can only recognize "bird" and "bottle", and the object recognition is wrong.

I took a pair of diagonal pliers and a pen, one to identify as a bird and the other to identify as a boat.

Then I searched the internet for a small ball and it was identified as a "bird" and a "bottle". Not sure why?

So how can we set it up to recognize the correct object? The manufacturer's firmware needs to be updated.

Does object recognition require training? Or is it built-in to the manufacturer's firmware?

It comes with the manufacturer. It seems that I haven't found how to train it.

That accuracy is indeed difficult to improve.
