foglamp-south-dht11 (Raspberry Pi)

FogLAMP South Plugin for DHT11 temperature and humidity sensor, for Raspberry Pi.

Hardware

A DHT11 plugged directly into the GPIO pins of a Raspberry Pi, the default configuration is to use GPIO4 for the data.

Installation

The plugin can be installed with given requirements.sh or with below manual steps:

$ pip3 install -Ir python/requirements-dht11.txt --no-cache-dir
