DS18B20 Temperature

The DS18B20 Temperature is a board I/O module in the LabWired part catalog. Its catalog type is ds18b20. It connects to the MCU over GPIO. The catalog gives a supply range of 3–5.5 V. It has 3 pins. This part is its pins. There is no separate device model because the MCU’s own GPIO/PWM/ADC model already is the simulation.

From the catalog: 1-Wire bit timing is not modelled; temperature is host SimInput for labs that abstract the bus.

How to simulate the DS18B20 Temperature in LabWired

  1. Open the Playground at app.labwired.com and place an MCU board.
  2. Add the DS18B20 Temperature (catalog type ds18b20).
  3. Connect VDD and GND to the supply and ground of the board. Use a supply inside the catalog range of 3–5.5 V.
  4. Connect DQ to a free GPIO pin.
  5. Run the firmware. It reads and drives these pins through the GPIO, PWM and ADC models of the MCU. The part has no separate device model.
