What are the dimensions of the load cell? (The diagram says 3.4mm and the description says 34mm)

Hi friend, the dimension of the load cell is 34mm. We change the diagram now. Thank you.

Do you have a version that can be used to measure a total of 2kg over 4 sensors. For example to monitor the weight of an item on a small platform?

The following are other 2 types sensor I have, https://www.amazon.co.uk/Amplifier-Electronic-Kitchen-Weighing-Arduino/dp/B07T48VZZF/ref=sr_1_33?keywords=wishiot&qid=1567048855&s=gateway&sr=8-33 https://www.amazon.co.uk/dp/B07G2QVVH3/ref=twister_B07G2RRNSQ?_encoding=UTF8&psc=1

Can I connect these to an arduino, which when walked upon triggers the arduino to subsequently open & close a sliding door?

They’re ideal to connect to an Arduino and you can then connect the board to motor drivers or a relay to drive your motors. However, these are quite thick, so they’d have to be within a step or over a void in the floor. They’re not thin enough to just tuck under a floor covering.
