Connect to server
= Set up general
- change host name = basestation-01, edit in /etc/hosts, and /etc/hostname then "sudo /etc/init.d/hostname.sh"
- eth0 connect inet DHCP
= Temp/Humidity Sensor
- get pigpio library, install.
cd ~ wget abyz.co.uk/rpi/pigpio/pigpio.zip unzip pigpio.zip cd PIGPIO make make install
- get dht22 example
- set up pigpiod at boot
- if using DHT11 the set up different file for DHT11! here is replacement to modify call to include (true) for DHT11)
- make sensor script file and change chmod 755 for executable

Camera sending image to Server
