How to interface a measuring light curtain with Arduino or Raspberry Pi?
Yes, you can interface DADISICK DK-QL measuring light curtains with Arduino or Raspberry Pi using the RS485 output. For Arduino, connect via an RS485-to-TTL module. For Raspberry Pi, use a USB-to-RS485 adapter. Both read measurement data through serial communication.
Quick Start Steps
Arduino: RS485 to TTL
Connect MAX485 module: DI to TX, RO to RX, DE/RE to digital pin. Power from 5V.
Raspberry Pi: USB-RS485
Use USB-to-RS485 adapter. Connect A+/B- terminals. Install pyserial library.
Read Data
Configure 9600 baud, 8N1. Send read command to DADISICK device address. Parse received measurement bytes.
This is ideal for prototyping, education, or custom measurement applications. For production systems, DADISICK recommends PLC-based integration for industrial reliability.
