Links for code samples about sensors with WiPy2.0



  • I need to know if there are some working code for WiPy2.0
    for any "sensors". I know it is starting project but maybe somwhere are.
    I am interested in sensors like:

    • temperature:
      * ds18b20
      * DHT11 and DHT22

    • display:
      LCD 16x2 (HD44780)

    • distance
      HC-SR04

    any other...

    I'm using a PCF8591 I2C extender with a HD44780 compatible display. You can find several code examples and libraries for micropython on github that require minimal changes.

    HC-SR04

    This one requires Timer support to be implemented first (hopefully in tomorrow's firmware release).

    Never used the DHT* sensors so not sure about their communication protocol.

    We are working on finishing an example project with a PIR sensor, expect this soon on the forum. I hope that will help you to get started implementing your own sensors.
