Pulse-oximeter. Arduino library for the MAX30102 (https://datasheets.maximintegrated.com/en/ds/MAX30102.pdf). Wraps the SparkFun MAX3010x sensor library (https://github.com/sparkfun/SparkFun_MAX3010x_Sensor_Library) written by Nathan Seidle and Peter Jansen. This XOD library is a work in progress - a node for measuring oxygen saturation will be added soon.
Time-of-Flight (ToF) sensor. Arduino library for the ST VL53L1X sensor (https://www.st.com/en/imaging-and-photonics-solutions/vl53l1x.html). Wraps the Pololu VL43L1X library for Arduino (https://github.com/pololu/vl53l1x-arduino).
CO2, relative humidity and temperature sensor. Arduino library for the Sensirion SCD30 sensor module (https://www.sensirion.com/en/environmental-sensors/carbon-dioxide-sensors-co2/). Wraps a modified version of the SparkFun SCD30 Arduino Library (https://github.com/sparkfun/SparkFun_SCD30_Arduino_Library).
