  • ADXL345 3-Axis Tilt Digital Gravity Acceleration Sensor

    ADXL345 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.

    APDS-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.

  • HC-06 Bluetooth serial pass-through moduleHC-06 Bluetooth serial pass-through module1

    HC-06 Bluetooth serial pass-through module

    This Bluetooth module can easily achieve serial wireless data transmission. Its operating frequency is among the most popular 2.4GHz ISM frequency band (i.e. Industrial, scientific and medical). It adopts Bluetooth 2.0+EDR standard. In Bluetooth 2.0, signal transmit time of different devices stands at a 0.5 seconds interval so that the workload of bluetooth chip can be reduced substantially and more sleeping time can be saved for bluetooth. This module is set with serial interface, which is easy to use and simplifies the overall design/development cycle.
