Nt18b07 Manual [repack] Guide

The actual payload (maximum length of 16 bytes ) . Checksum (XOR): Used for error verification . Common Commands

Supports up to 247 modules on a single RS485 bus via hardware address modification (RS485 repeaters are required if cascading more than 16 modules). Physical Dimensions: 60 mm × 37 mm × 14 mm. Weight: 19 grams. Pinout and Hardware Wiring Guide

Connect the to the Relay NO terminal.

According to the Modbus RTU Protocol Guide , the module can be configured for automatic temperature reporting at intervals ranging from 1 to 255 seconds.

For projects requiring more than 7 temperature sensors, multiple NT18B07 modules can be cascaded on the same RS485 bus. By assigning a unique Slave ID to each module (up to a theoretical maximum of 247 devices), a single MODBUS master can monitor hundreds of temperature points. If you plan to use more than 16 modules, an RS485 repeater is recommended to maintain signal integrity. nt18b07 manual

A research project from the 5th International Conference on Agricultural Engineering (AESAP 2023) successfully used the NT18B07 to build a low-cost IoT data logger for monitoring palm sugar drying. The system used an ESP32 to access the seven temperature channels from the NT18B07 and convert the MODBUS RTU protocol into the MQTT format, which was then sent to the Adafruit IO cloud platform and recorded in a Google Sheet. The system achieved a measurement accuracy and precision level of over 99%, showing the NT18B07 is well-suited for industrial IoT applications.

The official documentation is maintained within the IOControl library as part of the Sming Framework, and is available at https://smingdev.readthedocs.io/en/latest/_inc/Sming/Libraries/IOControl/docs/nt18b07/ . The actual payload (maximum length of 16 bytes )
