Node for measuring the amount of free Static Random Access Memory (SRAM). Based on https://github.com/mpflaga/Arduino-MemoryFree. For more information on getting the most from your Arduino memory, see: https://learn.adafruit.com/memories-of-an-arduino.
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 in the industry and features an ultra-wide 22-bit dynamic range from 0.045 lux to 188,000 lux.
XOD library for the SparkFun Pulse Oximeter and Heart Rate Monitor (SEN-15291). The sensor is an I²C based biometric sensor, utilising two chips from Maxim Integrated: the MAX32664 Bio Metric Sensor Hub and the MAX30101 Pulse Oximetry and Heart-Rate Module.
