hygrometer-thermometer SI7021 node.

This will filter and stabilize a noisy signal. If tuned well, it can be very fast and precise.

Node for using the sim28-GPS device. It can either show the current Latitude and Longitude, or display all the incoming information from the device on the serial monitor for tracking your position using other software.

Library to work with NB-Not (Narrow Band Internet of Things) module SIM7020 with built-in support network Protocol MQTT (message queuing telemetry transport). This Library is a tool for working with AT commands and can be easily converted to work with other modules of the SIMCOM family.

A simple communication protocol for a UART interface. To read more follow https://medium.com/p/9ce67cc69d3c

SinGen library. Generate's through PWM, two sinusoidal signals opposite each other, the frequency is determined by Hz

Allows the use of multiple buttons on a single analog input. Each button to be wired in series with differing levels of resistors to create voltage outputs of differing values.

SIRAJ Ventilator -LCD-20X4 -ONLY FOR SIRAJ OPEN SURCE Ventilator SIRAJ Emergency Ventilator Project -The SIRAJ Ventilator is an automated bag valve mask (BVM) device utilizing off-the-shelf components to provide safe and continuous hospital-grade mechanical ventilation for COVID-19 patients on an opensource basis. • The SEVP 4 is a controllable, automated add-on solution to the existing and widely available Bag Valve Mask (BVM). The device compresses the BVM with a mechanical system that is able to provide consistent and accurate ventilation with positivepressure. • This solution exists within the top range of highacuity limited-operability (HALO) ventilator solutions with an a priori design to produce volume and pressure cycled ventilation that includes positive end-expiratory pressure (PEEP) and enriched oxygen sources.

Siren Modulator can be use in many diffrent projects from Fire brigade or Police vechicles models up to seriouse Alarm systems. With this NODE you will be able to control sound frequency range nad sequence lenght.

Adafruit SleepyDog Arduino Library Arduino library to use the watchdog timer for system reset and low power sleep. Currently supports the following hardware: Arduino Uno or other ATmega328P-based boards. Arduino Mega or other ATmega2560- or 1280-based boards. Arduino Zero, Adafruit Feather M0 (ATSAMD21). Arduino Leonardo or other 32u4-based boards. Partial support for Teensy 3.X and LC (watchdog, no sleep). Adafruit Trinket and other boards using ATtiny MCUs are NOT supported.
