Build your own Z-Wave temperature sensor with an LCD display using Z-Uno development board.

This sketch shows how to connect I2C LCD display and OneWire temperature sensor DS18B20 to the Z-Uno — Z-Wave development board. Temperature values are read from the DS18B20 sensor, printed on the display and periodically reported to channel Multilevel Sensor.


You will need:

  • Z-Uno board
  • Breadboard
  • LCD display 16x2 (like this)
  • I2C/SPI LCD Backpack (like this)
  • DS18B20 temperature sensor (like this or waterproof variant like this)
  • 1 220 Ω resistor
  • 4 wires
