Android Bluetooth Control Device

 

Android Bluetooth Control Device Application is to allow you to control various electricaldevices up to eight devices and independentlycontrolled.
Use Android Bluetooth mobile device to  remote control your device with Bluetooth Receiver hardware Device.

เป็น Application ที่ทำให้คุณสามารถควบคุมอุปกรณ์ไฟฟ้าต่างๆได้ ถึง 8 อุปกรณ์โดย แยกควบคุมกันได้อย่างอิสระ

ผ่านระบบ Bluetooth ของเครื่องโทรศัพท์มือถือ Android เป็นตัว Remote Control ไปยังอุปกรณ์ภาครับ ( Bluetooth Receiver Hardware Device )

The program features.

- control up to  8 devices.
- Can be set Timer to ON / OFF the device and show the time.(the timer can be set to 1minute, 15 minutes, 30 minutes, 1hour, 2 hours,4 hours).
- Use with Receivingdevice (Bluetooth Receiver Hardware Device see below).

Design for the Android version 4 and a screen resolution of 480 x 800 (WVGA).

Freeware with AD (free software)

คุณสมบัติโปรแกรม

-          ควบคุมอุปกรณ์ได้ 8 อุปกรณ์

-          สามารถตั้งเวลา ปิด/เปิด แต่ละอุปกรณ์ได้ และแสดงเวลาการทำงาน และเวลาคงเหลือการตั้งเวลา 

(  (  เวลาที่สามารถตั้งได้ 1 นาที,15 นาที, 30 นาที, 1 ชั่วโมง ,2 ชั่วโมง , 4 ชั่วโมง ) 

-          ต้องใช้งานร่วมกับ อุปกรณ์ภาครับ ( Bluetooth Receiver Box )

ออกแบบ ค่าเริ่มต้น สำหรับ Android version 4 และ หน้าจอความละเอียด 480 x 800 ( WVGA )
