Logger Multisensor

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 application is for monitor multiple location (where node sensor is installed),
with theoretical bluetooth coverage limit 30 m.
For example, Arduino implement with LM35 sensor module as Ambient temperature sensing and ligjt sensing (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 :
- Arduino Uno or compatible (1 or 2), with bluetooth shield (with adjustable baudrate control)
- LM35 sensor and other electronics part such as CA3140, resistors, capacitors etc (see schematic on App)
those parts are quite popular. You can buy in any radio shack / electronic parts store near your region.
- A single LED connect to pin digital 13, or just use on board LED (were attached in pin 13)
- power source (can be use from USB port, or an DC 7-15V Adaptor)
- small Alumunium heatsink (attached on LM35 sensor), to increase ambient temperature sense accuracy
- USB cable for uploading program to Arduino
Happy Experiments with Android and Arduino !
