By default, the Node-RED editor is not secured - anyone who can access the IP address and port it is running on can access the editor and deploy changes. This is only suitable if you are running on a trusted network.
This section describes how you can secure Node-RED.
Ultra-Small Integrated AFE for Wearable, Optical Heart-Rate Monitoring and Biosensing
The AFE4404 is an analog front-end (AFE) for optical bio-sensing applications, such as heart-rate monitoring (HRM) and saturation of peripheral capillary oxygen (SpO2).
The device supports three switching light-emitting diodes (LEDs) and a single photodiode.
The current from the photodiode is converted into voltage by the transimpedance amplifier (TIA) and digitized using an analog-to-digital converter (ADC).
The ADC code can be read out using an I2C interface. The AFE also has a fully-integrated LED driver with a 6-bit current control.
The device has a high dynamic range transmit and receive circuitry that helps with the sensing of very small signal levels

LoRa/LoRaWAN ‘Mass adoption’ per Semtech’s Pegulu’s LoRa Alliance Vancover pitch
How Can Communications Service Providers Make Money in IoT?
yep that’s for me 
LoRaWAN pager prototype , which was done about a year ago using im880A module and STM32F429 discovery board. Touchscreen for sending messages, interface in English and in Russian, LED for showing status (sending, receiving, keep alive messages). DIY LoRaWAN gateway on IMST board and wifi with 3G connection Mikrotik. Works as private network and in public as well (with 3G).
