summary:
This module uses digital signals instead of traditional analog signals for transmission, reducing interference during the transmission process. Imported sensors and industrial grade high stability microcontrollers are used, which have the characteristics of long lifespan, low cost, high accuracy, and good long-term stability. The default baud rate for serial communication is 9600, with 8 data bits, 1 stop bit, and even parity; Its output interface is TTL output signal or RS485 signal, which can be confirmed by contacting sales personnel.
