General discussion • DHT22 Sensor with Pi 5 - import board error

Hi,

I'm trying to use a DHT22 humidity sensor with the Raspberry Pi 5. I figured it would be simple to do but I am struggling and I would appreciate any help. I've downloaded Raspi-blinka after activating my venv. However, I keep receiving the error that there is no module named 'board' when I run the following code (that I found online):

import time
import board
import adafruit_dht

# Initial the dht device, with data pin connected to:
dhtDevice = adafruit_dht.DHT22(board.D4)

# you can pass DHT22 use_pulseio=False if you wouldn't like to use pulseio.
# This may be necessary on a Linux single board computer like the Raspberry Pi,
# but it will not work in CircuitPython.
# dhtDevice = adafruit_dht.DHT22(board.D24, use_pulseio=False)

while True:
try:
# Print the values to the serial port
temperature_c = dhtDevice.temperature
temperature_f = temperature_c * (9 / 5) + 32
humidity = dhtDevice.humidity
print(
"Temp: {:.1f} F / {:.1f} C Humidity: {}% ".format(
temperature_f, temperature_c, humidity
)
)

except RuntimeError as error:
# Errors happen fairly often, DHT's are hard to read, just keep going
print(error.args[0])
time.sleep(2.0)
continue
except Exception as error:
dhtDevice.exit()
raise error

time.sleep(2.0)


I am very confused. Please help me.

Thank you.
