ADXL345 3-Axis Tilt Digital Gravity Acceleration Sensor
Developments Boards, Modules & Sensors, Robots & KitsADXL345 3-Axis Tilt Digital Gravity Acceleration Sensor
ADXL345 Tripple Axis Accelerometer Board is a small, thin, low power, 3-axis accelerometer with high resolution (13-bit) measurement at up to ±16g. Digital output data is format as 16-bit twos complement and is accessible through either a SPI (3- or 4-wire) or I2C digital interface. calcuttaelectronics.com
The ADXL345 Tripple Axis Accelerometer Board is well suited for mobile device applications. It measures the static acceleration of gravity in tilt-sensing applications, as well as dynamic acceleration resulting from motion or shock. Its high resolution (4 mg/LSB) enables measurement of inclination changes less than 1.0°.
Several special sensing functions are provided. Activity and inactivity sensing detect the presence or lack of motion and if the acceleration on any axis exceeds a user-set level. Tap sensing detects single and double taps. Free-fall sensing detects if the device is falling. These functions can be mapped to one of two interrupt output pins. An integrated, patent pending 32-level first in, first out (FIFO) buffer can be used to store data to minimize host processor intervention.
Low power modes enable intelligent motion-based power management with threshold sensing and active acceleration measurement at extremely low power dissipation.

Air-core Coil Adjustable Inductance 3.5T
Low frequency inductors are constructed like transformers, with cores of electrical steel laminated to prevent eddy currents. … Some inductors have an adjustable core, which enables changing of the inductance. Inductors used to block very high frequencies are sometimes made by stringing a ferrite bead on a wire.

Alcohol Sensor MQ3 Module for all MCU
This is a simple to use MQ-3 Alcohol Detector Gas Sensor Module which can sense the presence of Alcohol in the air. The module uses our MQ-3 sensor. It simplifies the interface to the odd pin spacing of the sensor and provides an interface through standard 4 x 0.1″ header pins. It provides an analog output corresponding to the concentration of the gas in the air and an easy to use digital output. The onboard potentiometer can be used to set the maximum gas concentration beyond which the digital output gets triggered. Just power the module with 5V set the threshold and you can start getting the gas concentration of the air around the sensor! An onboard LED signals the presence of any gas. Perfect sensing alcohol concentration on your breath just likes common breathalyzer.

APDS-9930 Non-contact proximity and Ambient Light sensor
Developments Boards, Modules & Sensors, Robots & KitsAPDS-9930 Non-contact proximity and Ambient Light sensor
APDS-9930 is a digital I2C compatible interface ambient light sensor (ALS) and proximity sensor with IR LED in a single 8-pin package. The ambient light sensor utilizes dual photodiodes to approximate the human eye response with a low lux performance at 0.01 lux. This high sensitivity allows for the device to operate behind a darkened glass. The proximity sensor is fully calibrated to detection of objects to 100 mm thus eliminating the need for factory calibration of the end equipment or sub-assembly. The proximity detection feature operates well from bright sunlight to dark rooms. The addition of the micro-optics lenses within the module, provide highly efficient transmission and reception of infrared energy which lowers overall power dissipation. In addition, an internal state machine provides the ability to put the device into a low power mode in between ALS and proximity measurements providing very low average power consumption.
