It causes exception ETIMEOUT
native GitHub micropython driver source here:
Code: Select all
import dht import time aPin = 14 #Pin = machine.Pin(aPin, machine.Pin.IN, machine.Pin.PULL_UP) Pin = machine.Pin(aPin) Obj = dht.DHT22(Pin) time.sleep_ms(250) Obj.measure() -> exception : ETIMEOUT

However this driver works good on micropython wirh DHT22 sensor
It seems that DHT21 and DHT22 are similar. Or not?
On a raspberry i use another python driver from Adafruit_DHT and both DHT21 and DHT21 are working good
how to solve this problem using micropython on ESP8266 chip?
