## A project using:

- [50m/164ft Laser Distance Measuring Sensor](https://www.aliexpress.com/item/32793950499.html?spm=2114.12010610.8148356.13.781e399eK4pNj7)

(do not recommend this model, it has [very tiny pcb pads](laser.jpg) for soldering RX/TX wires - different from the shop's photo, 100m model should be better)

- Arduino Uno

- I2C LCD

- button for tare

## Used for a proper positioning of bales:

## USB to UART - it does not shift rx/tx to 3.3V - it is better to use Logic Level Converter https://www.aliexpress.com/item/4000587260340.html (although maybe not necessary)
