The MMA7361L is a low power, low profile capacitive micromachined accelerometer featuring signal conditioning, a 1-pole low pass filter, temperature compensation, self test, 0g-Detect which detects linear freefall, and g-Select which allows for the selection between 2 sensitivities. Zero-g offset …

The ADXL335 is a small, thin, low power, complete 3-axis accelerometer with signal conditioned voltage outputs. The product measures acceleration with a minimum full-scale range of ±3 g. It can measure the static acceleration of gravity in tiltsensing applications, as …

The MAX44009 ambient light sensor features an I²C digital output that is ideal for a number of portable applications such as smartphones, notebooks, and industrial sensors. At less than 1µA operating current, it is the lowest power ambient light sensor …

This example was for an RGB Led display I saw. It contains 8 led’s, 3 control lines for the red, green and blue and also requires a 5v connection. The LEDs are common cathode types so a low (0v) switches …

Out of the box the Arduino IDE does not support multi-tasking effectively. the good news its easy to add support via a library to the Arduino IDE Most operating systems appear to allow multiple programs or threads to execute at the …

One nice feature that has been introduced in the Arduino IDE is the ability to run the software as a portable version. The portable version will store the sketchbook, the libraries and the hardware folder locally where you want it. …

The Si7021 I2C Humidity and Temperature Sensor is a monolithic CMOS IC integrating humidity and temperature sensor elements, an analog-to-digital converter, signal processing, calibration data, and an I2C Interface. The patented use of industry-standard, low-K polymeric dielectrics for sensing humidity …

The SHT1x digital humidity sensor is a reflow solderable sensor. The SHT1x series consists of a low-cost version with the SHT10 humidity sensor, a standard version with the SHT11 humidity sensor, and a high-end version with the SHT15 humidity sensor. …

The PCF8563 is a CMOS Real-Time Clock (RTC) and calendar optimized for low power consumption. A programmable clock output, interrupt output, and voltage-low detector are also provided. All addresses and data are transferred serially via a two-line bidirectional I²C-bus. Maximum …

The DS3231 is a low-cost, extremely accurate I2C real-time clock (RTC) with an integrated temperature-compensated crystal oscillator (TCXO) and crystal. The device incorporates a battery input, and maintains accurate timekeeping when main power to the device is interrupted. Features Highly …
