DHT Pure Python library for Pycom board

This simple class can be used for reading temperature and humidity values from DHT11 and DTH22 sensors on Pycom Board. Thanks to szazo for the original source code.

Usage

  1. Instantiate the DHT class with the pin number and type of sensor (0=DTH11, 1=DTH22) as constructor parameters.
  2. Call read() method, which will return DHTResult object with actual values and error code.

For example:

import pycom
import time
from machine import Pin
from dth import DTH

pycom.heartbeat(False)
pycom.rgbled(0x000008) # blue
th = DTH(Pin('P3', mode=Pin.OPEN_DRAIN),0)
time.sleep(2)
result = th.read()
if result.is_valid():
    pycom.rgbled(0x001000) # green
    print("Temperature: %d C" % result.temperature)
    print("Humidity: %d %%" % result.humidity)

For working example, see `dht11_example.py` (you probably need to adjust pin for your configuration)
