Pure Python library for reading DHT sensor (DHT11, DHT22, AM2302) on Pycom
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
- Instantiate the
DHT
class with the pin number and type of sensor (0=DTH11, 1=DTH22) as constructor parameters. - Call
read()
method, which will returnDHTResult
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)
