Low power consumption, suitable for battery-operated devices.
Connect the TXD of the NT18B07 to the RXD of your microcontroller (e.g., Arduino, STM32) and the RXD of the NT18B07 to the TXD of the microcontroller. Ensure a common ground (GND) is used. 4.2. Initial Testing Power the module using 5VDC. Connect the module to a PC using a USB-to-TTL converter. Open a terminal emulator (e.g., PuTTY) set to 19200 baud. Present a 125KHz card.
: NTC thermistors are non-polarized resistors. Connect one lead to the channel signal pin and the other to the shared channel ground terminal.
Serial UART (TTL level or RS232 depending on model). Operating Frequency: 125KHz. nt18b07 manual
Note: Some NT18B07 units are "Code Search" compatible. In that case, follow your universal remote's auto-search manual.

The designed for industrial automation, smart building monitoring, and data logging systems. Operating on the Modbus RTU protocol , this compact hardware unit allows hardware engineers and developers to aggregate up to seven independent temperature sensors over a single serial communications link, minimizing wiring and maximizing data density.

The raw Modbus value must be divided by 10.0 to obtain the temperature in Celsius. For example:
Ensure the NTC thermistors are 10K B3950 type. Other NTCs will not provide accurate readings. Open a terminal emulator (e
Typically 5VDC (check specific module version for 3.3V compatibility).
This article serves as a comprehensive manual for the NT18B07, covering specifications, wiring, protocol details, and integration examples. 1. Technical Specifications
All temperature readings and parameters are mapped to 16-bit holding registers.
The temperature data is typically stored in input registers. The data format is usually a 16-bit signed integer or a 32-bit float, often with a scale factor of 0.1 or 0.01 depending on the specific firmware version.
