Simple homemade Arduino based alarm system. It emails and texts me when me door opens! It consists of:
- Ethernet Shield
- Piezo Buzzer
- Blue LED
- Two long strands of 22 gauge wire
The system is not connected to a computer. Instead, it connected directly to the internet with an Ethernet shield. I get emails or texts when:
- the door opens
- the door has been kept open for more than 15 seconds (so if the door sensor falls off or something, I know.)
- the system reboots, so if I lose power I will know.
Uses a DHCP library to get an IP address. SMTP server is hard coded (as is the email address to send texts/emails to).
