DHT22 Python library This simple class can be used for reading temperature and humidity values from DHT22 sensor on Orange PI.
Fork with some patches from https://forum.armbian.com/topic/5718-need-help-with-dht11-temp-sensor-and-python-code/
- Home made to ensure read is available even if there is not exactly the expected data lenght AM2301 usage
- Usage with Python3
- Usage with pyA20 for OPi Zero https://github.com/nvl1109/orangepi_zero_gpio
- Used with a Orange Pi Zero H2+
- Used with a AM2301 setup as DHT22
- Used with a DHT11
- Used within a display SSD 1306 with https://github.com/jingl3s/OrangePiZero_OLED_Dht_display
Example:
from pyA20.gpio import gpio
from pyA20.gpio import port
import dht
import time
import datetime
# initialize GPIO
PIN2 = port.PA6
gpio.init()
# read data using pin
instance = dht.DHT(pin=PIN2)
while True:
result = instance.read()
if result.is_valid():
print("Last valid input: " + str(datetime.datetime.now()))
print("Temperature: %.2f C" % result.temperature)
print("Humidity: %.2f %%" % result.humidity)
time.sleep(1)Please see tutorial: http://www.piprojects.xyz/temperature-sensor-orange-pi-python-code/
