Description
I'm relatively new to circuitpython, only started yesterday so apologies for any mistake I've made here.
Device: Teensy 4.0
DHT22 connected to pin D15
Powered from 3v3
PULL up resistor on data pin, actually the same circuit I've used successfully on other devices, just moved to the teensy 4.0
Coding on a macbook pro using Mu 1.0.3
adafruit_dht library copied to /lib from the latest library download: adafruit-circuitpython-bundle-5.x-mpy-20200417
No other modules in the lib folder
Code:
import board
import time
import adafruit_dht
print('Initialising...')
dht_device = adafruit_dht.DHT22(board.D15)
time.sleep(2)
print(dht_device)
while True:
temperature = dht_device.temperature
humidity = dht_device.humidity
print(str(temperature))
print(str(humidity))
time.sleep(2)
Full serial output:
code.py output:
