Nt18b07 Manual __link__ Jun 2026
When linking the module to an ESP32/ESP8266, configure the UART and modbus controller in YAML. The configuration requires setting the appropriate UART pins, 9600 baud rate, and creating a lambda function to convert 2-byte register values into floating-point temperatures, properly handling two's complement for negative values.
Uses the standard Modbus RTU protocol (supporting function codes 03 and 06) with a default baud rate of 9600.
Before diving into installation, let us review the core technical specifications and physical layout of the board. nt18b07 manual
The NT18B07 breaks out its power, serial bus, and sensor interfaces across dedicated terminal blocks. Proper wiring prevents signal reflections, ground loops, and hardware failure. 1. Power Supply and RS485 Communication Terminals
