DHT22 1 wire

Christopher Whitney · 31 Jul 2016, 03:02

Working with DHT22 one wire and I have done https://wiki.onion.io/Tutorials/Reading-1Wire-Sensor-Data

and I have gone thru everything on this community pages here. It seems as if my w1_slave is missing?

when I run this command
cat /sys/devices/w1_bus_master1/00-180000000000/w1_slave
I get this.
cat: can't open '/sys/devices/w1_bus_master1/00-180000000000/w1_slave': No such file or directory

@Christopher-Whitney What do you see when you issue this command?

ls -l /sys/devices/w1_bus_master1/

@Christopher-Whitney DHT22 doesn't use 1-wire protocol, it uses its own single-wire protocol.

EDIT: Whoops, I just replied to a 6 months old thread.
