Pulse and Body temperature implementation for design of the safety system

Samples the input at a given rate and number of samples, outputs the average value for n samples

A block that scales an inputted value between -1 and 1 to a value between 0 and 1.

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).

Sensirion SCD4x CO2, relative humidity and temperature sensor. Wraps https://github.com/Sensirion/arduino-i2c-scd4x

Use the SD-Card to store and retrieve data

Library for Sensirion SDP6x differential pressure sensors, including the SDP610. Wraps a modified version of https://github.com/EngineerTony/Sensirion_SDP6x_pressure_sens. Data sheet: https://sensirion.com/media/documents/63859DD0/6166CF0E/Sensirion_Differential_Pressure_Datasheet_SDP600Series.pdf

A basic library to use the Seeed I2C LCD 16x2 device

XOD library to interface with the Amperka SegM8 display module.

'Select' type nodes

Alternate switching of 5 relays. After each lap of relay switching, there is a situation when all relays are disconnected. Pulse OFF PULSE turns off the relay immediately. The next impulse turns it on again.
