ADAFRUIT DHT LIBRARY

by khriss75 on Fri Feb 15, 2019 8:42 am

Dear,
I'm using DHT22 sensor and noted some isse:
ver. 1.2.3 work fine but loop time is about 270ms
ver. 1.3.2 loop time about 5ms (good) but I have some "spike". I read humidity and temperature every 3 minutes. Sometimes and random I have a value that is the half of previous measure. Example previous measure: 12.4°C the spike after 3 minutes is 6.2°C and the last measure is 12.5°C.
ver. 1.3.3 Works on my breadboard, loop time about 5ms but returns "nan" if the cable length about 2 meters or more (ver. 1.2.3 and 1.3.2 works with my installation and cable about 5 meters).
