Rpi Motion and temperature sensor
Raspberry pi motion and temperature sensor
Basic setup for Rpi with the camera module using Motion and a DS18B20 temperature sensor on Raspbian
Materials:
4.7k resistor for the temperature sensor
Sd Card with Raspbian
network cable or USB wifi adaptor
case for the raspberry pi
optional IP65 waterproof box for outside deployment

To do list after burning new Raspbian image to card:
expand file system on card
change password
activate Rpi Camera - test with: raspistill -o image.jpg
turn SSH on
set time and location

Deployed inside the house for trials using a wifi adaptor
Note: The Raspberry Pi even inside the house in the winter at -17 degrees Celsius had the SD card fail but this was probably due to the fact that the SD card was a no name cheap one.
