Advise on the esphome weight sensor

I want to make a small automatic feeder using esphome for chinchillas with a portion measurement function. Please advise on a small sensor I can use for this project. The portion size is 30-60 grams.

Also, if you know of a better way to do this, any advice?

I dont have a pet, but these I see regularly in sale for around 60 euros:
