DS18B20 Temperature Acquisition Module Control Board TTL Communication Interface | Бытовая техника

Powerful:TK-DS18B20The module provides three optional interfaces.TTLInterface,232Interface and485Interface.

TTLInterface: Suitable for MCU,ARMThe serial port connection of microprocessors,TTLLevel signal.

RS-232Interface:PCOfCOMPort connection, implementationPCandDS18B20Data transfer.

RS-485Interface: Long-distance communication, capable of acquisition500~1000MExternal temperature data to achieve remote monitoring.

Module Addressing: In485In the interface mode, the bus connection can be realized. Each module can set a hardware address, and the address range is0~255So, there can be as many as256Each module consists of multi-point acquisition.

Communication mode: serial communicationBaud rate9600No check.
