Written by Kevin (KTOWN) Townsend & Limor (LADYADA) Fried for Adafruit Industries. Please support Adafruit and open-source hardware by purchasing products from Adafruit! ![]() About this DriverĪdafruit invests time and resources providing this open source code. freeing you up to focus on the data, rather than digging through the datasheet to understand what the sensor's raw numbers really mean. Light sensors will always report units in lux, gyroscopes will always report units in rad/s, etc. The Earth Listener is an Arduino based sensor device that reads multiple environmental values to indicate the air quality. It provides a simple abstraction layer between your application and the actual sensor HW, allowing you to drop in any comparable sensor with only one or two lines of code to change in your project (essentially the constructor since the functions to read sensor data and get information about the sensor are defined in the base Adafruit_Sensor class).ġ.) You can use the data right away because it's already converted to SI units that you understand and can compare, rather than meaningless values like 0.1023.Ģ.) Because SI units are standardised in the sensor library, you can also do quick sanity checks working with new sensors, or drop in any comparable sensor if you need better sensitivity or if a lower cost unit becomes available, etc. Velleman ISD1820 Voice Record/Play Module Velleman.

Velleman 5-in1 Allbot Robot Set Compatible w/ Arduino (Allbot2) Velleman. The Adafruit Unified Sensor Library ( ) provides a common interface and data type for any supported sensor. Velleman have now designed some shields modules for your Arduino allowing to interface and control applications from your micro-controller board. ![]() More information on the MMA8451 can be found in the datasheet: What is the Adafruit Unified Sensor Library? Arduino boards are able to read inputs light-on sensor, a finger on. The MMA8451 is a low-cost but high-precision digital accelerometer that uses repeated-start I2C mode, with adjustable data rata and 'range' (+/-2/4/8). Arduino is an open-source prototyping platform based on easy-to-use hardware and software. This driver is for the Adafruit MMA8451 Accelerometer Breakout ( ), and is based on Adafruit's Unified Sensor Library (Adafruit_Sensor).
