Python program for interfacing a raspberry pi with a cellular modem, ip camera, and other apparatus to construct a SMS based pig trap
You will need the following hardware:
- A Raspberry Pi (Any version as long as it has the same GPIO)
- A fenced in area with a door set to be closed by releasing a solenoid
- A Fona 3G module
- An IP camera with an ethernet cable to directly connect to the Pi
- A motion detector
- A PiFace relay plus
You will need to set up hostapd on the Raspberry pi to act as a network for the IP camera
- You will need to compile and install OpenCV on the Raspberry Pi with the Python extensions
- Simply install the python requirements as follows:
python3 -m pip install -r requirements.txt
- Wire up the components as shown in the
PigPenSchematicschematic file - Set up the configuration YAML file
```
owner:
- The phone number the SIM card is registered to
camera:
relayNumber: The index you want to use for the camera
relayAddress: The index of the relay the camera power is hooked up to
cameraIP: The IP address of the camera on the network you set up with `hostapd`
user: The username required to access the camera
password: The password required to access the camera
port: The port the camera uses
channel: The channel of the camera you want to use. Usually 1
subtype: The subtype of the camera you want to use. Usually 0
maxBytes: The maximum amount of bytes you want to use before triggering the image culling process
gate:
relayNumber: The index you want to use for the gate
relayAddress: The index of the relay the gate solenoid is hooked up to
detectionPin: The pin the solenoid state detection is hooked up to
motion:
pin: The pin the motion detector is hooked up to
delay: The minimum amount of time required to pass between detection events
```
- I would also recommend setting up a systemd service file that runs the program on system boot
