MMM-HDC1080

This module shows the temperature and humidity of a HDC1080 Sensor by using the I2C of the RaspberryPi and displays it at your MagicMirror² https://github.com/MichMich/MagicMirror. The Pins 2 and 3 are used for I2C and can not be changed. The main function and code is from @Bangee44 (https://github.com/Bangee44/MMM-DHT22) where he used it for a DHT22-Sensor.

Dependencies

• Enable your I2C of the RaspberryPi by going to Settings->RaspberryPi Configuration->interfaces->Enable I2C
• An installation of MagicMirror²
• [WiringPi] (http://wiringpi.com/download-and-install/)

Installation

Navigate into your MagicMirror's modules folder:

cd ~/MagicMirror/modules

Clone this repository:

git clone https://github.com/MichaelF1/MMM-HDC1080

Setup the address (default is 0x40) of your used I2C - HDC1080 Sensor in the ReadHDC1080.c-file at ~/MagicMirror/modules/MMM-HDC1080/:

int iI2cAddress = 0x40; //put in your I2C-Address here

If you do not need to change the file you are fine now, but if you have to you have to compile it with:

cc -Wall ReadHDC1080_Pi.c -o ReadHDC1080 -lwiringPi

Navigate to the new MMM-HDC1080 folder and make ReadHDC1080 executable.

cd MMM-HDC1080
chmod 755 ReadHDC1080

You can change the ReadHDC1080.c file for your own needs if you like to. You'll have to recompile it using wirinpi lib.

cc -Wall ReadHDC1080.c -o ReadHDC1080 -lwiringPi

Configure the module in your config.js file.

Using the module
