GNSS IoT Positioning: From Conventional Sensors to a Cloud-Based Solution
’ why is it so yellow in here ? ’
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
