W5100S-EVB-Pico FreeRTOS Sensor Monitoring With the Node-RED

The ethernet is a basic communication technology for remote monitoring. The W5100S-EVB-Pico combined RP2040 and W5100S to use ethernet.

Supplies

WIZnet W5100S-EVB-Pico

Step 1: Sensors

There are RP2040 FreeRTOS Examples that can use with W5100S-EVB-Pico. And I try to connect some sensors.

SENSIRION SHT3X-DIS

: Humidity and Temperature Sensor

InvenSense MPU-6050

: Integrated 6-axis MotionTracking device that combines a 3-axis gyroscope, 3-axis accelerometer, and a Digital Motion Processor.

These are I2C interface devices. Fortunately, the pico-examples provide a good reference for I2C.

The W5100S-EVB-Pico gets data from sensors every 2 seconds, and it sends data to TCP Client which is connected.

Step 2: Node-RED

The Node-RED connects to W5100S-EVB-Pico as a TCP Client. It shows data on the widget.

Finally, I can create a task for sensing and I can show my Node-RED dashboard.

Thank you for reading this.
