Introduction
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.
