Logger Multisensor

Logger pour plusieurs appareils comme capteur de noeud via les réseaux Bluetooth (max 8 dispositif)

The cheapest and free solution to make Android devices as server node sensor,

No need to buy expensive sensor nodes !

You can connect with 2 Arduino devices simultanously, using bluetooth 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 temperature sensing and light sense using LDR based sensor module.

This App is one of many project in our released Book (released in Indonesian only)

used as one of example content of my published books :

Inside the App included schematic diagram, Arduino connection and 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 (with adjustable baudrate control), or you can use two Arduino Bluetooth

- LM35 sensor and other electronics part such as CA3140, resistors, capacitors etc (see schematic on App) for each arduino (as sensor nodes)

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 (were attached in pin 13) for each Arduino/

sensor nodes

- power source (can taken from USB port, or you can use 7-15V DC Adaptor)

- small Alumunium heatsink (attached on LM35 sensor), to increase ambient 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 UPLOADED SPECIFIC CODES (AND BE READY TO CONNECT). OR THIS APP CAN WOULD CRASH.

Happy Experiments with Android and Arduino !
