Ultrasonic Sensor SI 2
(USB/Modbus)
The SI 2 is an extremely light and small ultrasonic sensor with digital signal output, which can be transmitted via USB or Modbus RS 485.
- Ultrasonic sensor with USB interface for the simplest realisation of applications
- 
Industrial-grade Modbus RS485 interface for smooth scaling 
- 
High flexibility, either use the appropriate Senzoro software for data analysis or develop your own software 
- 
Adheres magnetically (gluing also possible) 
- 
Python-API
