How to use it

• i2c-tools package is required, so you should install it before you get temperature as following command:
  

sudo apt-get update && sudo apt-get -y install i2c-tools

• Enable I2c function by editing /boot/config.txt,make sure it contain this two parameter as following:
  

device_tree=bcm2710-rpi-3-b.dtb
dtparam=i2c_arm=on

• • Or you can use this command to enable I2C:
    

sudo raspi-config

• • Select as this picture, then you can enable I2C easily.

• Please Remember to reboot your Raspberry Pi.
