Produktbeschreibung
Der ADXL345 ist ein stromsparender (40µA beim Messen, 0,1µA im StandBy) 3-Achsen Beschleunigungssensor, mit einer Auflösung von 13-Bit ist er sehr genau (4mg/LSB).
Die Messadten lassen sich über SPI (3 oder 4 Wire Betrieb) oder I2C auslesen.
Der Sensor enthält zahlreiche eingebaute Funktionen, wie z.B. Freie Fall Erkennung, Überschreitung eines Voreingestellten Messwertes.
Dieses Board besitzt einen ATmega328 der die komplette I2C/SPI Kommunikation mit dem ADXL345 übernimmt und die Daten der einzelnen Achsen auf einer microSD Karte loggen kann.
Vollständige Englische Beschreibung:
This is an evaluation board for the ADXL345 three-axis accelerometer.
The ADXL345 is an awesome little accelerometer, capable of measuring
acceleration of up to ±16g at up to 13-bit resolution. The evaluation
board includes everything you'll need to adjust the ADXL345's settings,
and monitor and log its outputs.
The on-board ATmega328 takes care of all the I2C/SPI communication with
the ADXL345, and it will also log the x-, y-, and z-axis acceleration
values onto a uSD card.
The board includes a USB interface, which allows you to read/write any
of the ADXL345's registers using a terminal emulator. The default baud
rate is 57600bps (8-N-1). The UART pins are also broken out allowing a
direct TTL interface with the processor.
Power can be supplied by 2xAA batteries, or with a 3.0-3.3VDC power
supply at the VCC/GND pins.
The ADXL345 evaluation board does not include batteries, uSD card or a
USB cable, check the related items section below for these products.
Note: Previous boards have been shipped without the Arduino
Bootloader preinstalled on the ATmega328. This issue has been fixed; in
all orders from now on the microprocessor will have the bootloader
loaded.
