Description

The cheapest and free solution to make Androiddevices as server node sensor,
No need to buy expensive sensor nodes !
You can connect with 2 Arduino devices simultanously, usingbluetooth network,
or you can modify the source code to enable connect max 8 devices(max Bluetooth piconet limit),

This app usage is for monitoring multiple locations node sensor(Arduino based), with theoretical bluetooth coverage approx 30 m(line of sight).

For example, using LM35 sensor module as Ambient temperaturesensing and light sense using LDR based sensor module.

This App is one of many project in our released Book (releasedin Indonesian only)
used as one of example content of my published books :

Inside the App included schematic diagram, Arduino connectionand link to the source code (Android and for Arduino).

Minimum Android & Software specifications :
- Android OS Gingerbread (API 9) or the latest
- Standard Bluetooth connection
- Internet connection, (only for access the advertising content,applications can still be used by offline)
- Android Application-Service Provider Amarino_2_v0_55 Amarino.apk
(for bluetooth connection to the Arduino)
can be directly downloaded by link:https://amarino.googlecode.com/files/Amarino_2_v0_55.apk
- Arduino software for uploading the program.

Hardware requirements :
- Two Arduino Uno or compatible, with two bluetooth shield (withadjustable baudrate control), or you can use two ArduinoBluetooth
- LM35 sensor and other electronics part such as CA3140, resistors,capacitors etc (see schematic on App) for each arduino (as sensornodes)
those parts are quite popular. You can buy in any radio shack /electronic parts store near your region.
- A LED connect to pin digital 13, or just use on board LED (wereattached in pin 13) for each Arduino/
sensor nodes
- power source (can taken from USB port, or you can use 7-15V DCAdaptor)
- small Alumunium heatsink (attached on LM35 sensor), to increaseambient temperature sense accuracy
- USB cable for uploading program to Arduino
- Amarino library (required for arduino codes).

BEFORE USING THIS APP, PLEASE PREPARE 2 ARDUINO WITH UPLOADEDSPECIFIC CODES (AND BE READY TO CONNECT). OR THIS APP CAN WOULDCRASH.

Happy Experiments with Android and Arduino !
