Arduino LM35 Temp Logger & LED

This application usage is as temperature logger based on LM 35 sensor (analog type, see the datasheet for details), LM35 should installed on Arduino Board using the Bluetooth SPP module or shield). Also to communicate your device with Arduino using through Bluetooth network.

Minimum Android specifications :

- Android OS Gingerbread (API 9) or the latest

- Standard Bluetooth connection

- Internet connection

- App Android Application-Service Provider Amarino_2_v0_55 Amarino. apk

(for bluetooth connection to the Arduino, without it the device cannot directly connect to Arduino)

can be directly downloaded by link: https://amarino.googlecode.com/files/Amarino_2_v0_55.apk

- Arduino software for upload the program.

Hardware side requirements :

- Arduino Uno or compatible, 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

- Amarino library (for arduino codes).
