/*!
 * @file Adafruit_MPRLS.h
 *
 * Designed specifically to work with the MPRLS sensors from Adafruit
 * ----> https://www.adafruit.com/products/3965
 *
 * These sensors use I2C to communicate, 2 pins (SCL+SDA) are required
 * to interface with the breakout.
 *
 * Adafruit invests time and resources providing this open source code,
 * please support Adafruit and open-source hardware by purchasing
 * products from Adafruit!
