What sensor for monitor network with camera and wifi
My ultimate goal is to install a series of weatherproof systems around my farm that: when a sensor is tripped, a camera takes a picture and a base station is notifed. At that time the unit reporting the activity is accesed from the base and the picture is downloaded.
I have an Arduino Uno and a Raspberry Pi and want to use Arduinos as the monitors and the RPi as base. I am working through Arduino tutorials now and I am just about ready to start on a prototype monotor. My first question is what should I use for a sensor? The PIR modules are less expensive the the Sonar sensors, a factor since I plan on five or six stations. But if I enclose them in clear boxes (Adafruit 905 or Otterbox 339) which sensor will work best in an enclosure?
