ADI claims lowest power accelerometer

Description The ADXL362 is an ultralow power, 3-axis MEMS accelerometer that consumes less than 2 μA at a 100 Hz output data rate and 270 nA when in motion triggered wake-up mode. Unlike accelerometers that use power duty cycling to achieve low power consumption, the ADXL362 does not alias input signals by undersampling; it samples the full bandwidth of the sensor at all data rates. The ADXL362 always provi ...

CMOS imager has 2Mpixel resolution

The higher resolution EV76C570 is the latest addition to e2v’s renowned industrial CMOS imaging sensor range. The device features an identical CLCC48 package with only a minor change in hardware, and retains optical compatibility with the 1.3MP Sapphire sensor that is already in full production. A 1/1.8 inch optical format is retained thanks to the reduced pixel size of 4.5µm x 4.5µm.  The SPI register bank ...

Arduino-based line follower robot using Pololu QTR-8RC line sensor

UPDATE FEB 2012: This guide is featured on Adafruit's blog http://www.adafruit.com/blog/2012/02/14/arduino-based-line-follower-robot/ This is Faz3a II, my first line-following robot, which I also hope to use for maze-solving. I used the Arduino Uno, Adafruit motor shield, Pololu's QTR-8RC line sensors and motors. You can build a cheaper and lighter version of this robot using the Atmel Atmega328 and the L29 ...

Magic Light Capacitance Sensor using an Arduino

This was my very first arduino project.  Its great for beginners. Fade the color or the lights my moving your hands near it.  It fades from a pretty purple blue to a firey red-orange. Its was SUPER easy to build, not to hard to write the code, and its really impresses people!  I gave it to my mother for christmas, and it was a big hit. Watch the video to see it in action! I apologize for the poor quality, I ...

Smart arrow uses ADI MEMS sensor

The ADXL346 is a small, thin, ultralow power, 3-axis accelerometer with high resolution (13-bit) measurement at up to ±16 g. Digital output data is formatted as 16-bit twos complement and is accessible through either an SPI (3- or 4-wire) or I2C® digital interface. The ADXL346 is well suited for mobile device applications. It measures the static acceleration of gravity in tilt-sensing applications, as well ...

DIY Infrared Sensor Module using Arduino

Have you ever wanted to make a line following robot but the infrared sensors were too expensive for you? Do you want to upgrade the robot in my other instructable? Well this instructable comes in two stages, Stage 1 is the prototyping stage, where you build the circuit on the bread board and debug it for design flaws. Stage 2 is fabrication where I’ll teach you how to create a strip board product that you c ...

Temperature Sensor for Shower using Arduino

With this device you diminish the use of water in your house or work. Instead of waiting to see vapor in the shower to get in, this device help you to know when the water its at the temperature you want and you can instantly enter to the shower. In this way you don't waste the water by not knowing when its ready. This device shows the temperature of the water with a led bar (made from 10 leds). The leds get ...

Arduino Controlled Motion Sensor

In this Instructable, I'll be explaining how to build a motion activated alarm! It uses an Arduino microcontroller, a PIR (passive infrared) sensor, and a type of alarm. You can use an LED indicator, a buzzer, or a piezo. That's the easy part. I will also be showing how to display to a character LCD screen, and over serial communication with a pair of XBee chips to relay the information to your computer! We ...
