Introduction

一个MT-DS模块的单独图片

MT-DS is a temperature processing module designed for Dallas Temperature Sensors. This module works as a bridge between Dragino MS12 and Dallas/Maxim Onewire temperature sensors. it read temperature from Dallas Temp Sensors and send it to Dragino via UART port. Dragino MS12 will forward the temp info to remote server.

Features

• Support devices:
  • DS18B20
  • DS1822
  • DS1820
• Use ATmega168-20au MCU.
• Show Sensor ID + Temp pairs as result.
• Support 8 OneWire buses (with pull up 4.7K Ohm resister) and up to 80 Dallas Temp Sensors in a single Dragino.
• Provide 5V power and GND to Dallas Temp Sensors.
• Auto-detect new added sensors or removed sensors.
• Remote upgrade via internet.
• Compatible with Arduino IDE for easy debug.
• Completely open source in both software and hardware, free to modify and change.
