Connecting a pull-up resistor is very important.
I have tried 4.7K and 10K resistors - did not help
And remember to use 3.3V instead of 5V.
I'm using this sensor: R1B1 DHT11, in tech specs it has "Working voltage: DC 5V". Anyway, I tried connecting to 3.3V - did not help
Did you checked if the CPU frequency is not simply to low ?
On this board I have also connected DS18B20 with 4.7K resistor - and it works fine Copy the Code
- # cat /sys/devices/system/cpu/cpu1/cpufreq/cpuinfo_cur_freq
Is there a way to check - what is wrong? Like, is the sensor working, maybe it is broken?
Did I connect correctly?
