Kali ini saya akan menjelaskan mengenai bagaimana cara membuat alat pengaman dengan menggunakan 3 device berbeda yaitu sensor kemiringan GY-61, GPS EM-411 dan sms gateway modem wavecom. Sebenarnya kegunaan alat ini yaitu untuk pengaman sepeda motor, jadi saat dicuri akan ada GPS yang melacak, dan juga jika sepeda motor dibawa maling pasti akan terdeteksi kemiringannya, kemudian sms gateway digunakan sebagai media pemberi kabar ke pemilik sepeda motor bahwa motornya dalam keadaan bahaya. Sms gateway yang digunakan yaitu modem wavecom fastrack serial port. jika si pemilik sepeda motor telah mendapatkan pesan bahaya maka untuk mematikannya tinggal sms balik dengan pesan #L. fungsi GPS disini yaitu jika motor dibawa maling pasti akan ada perubahan lokasi, dengan perubahan itulah maka akan memberitahu kepada pemilik via sms. Terlebih dahulu lokasi harus disimpan koordinatnya baru bisa dipakai.
