## Article

Original : <https://www.hackster.io/loveivyou/w5100s-evb-pico-freertos-sensor-monitoring-with-the-node-red-a3b9ab> The ethernet is a basic communication technology for remote monitoring. The W5100S-EVB-Pico combined RP2040 and W5100S to use ethernet.

[There are RP2040 FreeRTOS Examples](https://github.com/Wiznet/RP2040-HAT-FREERTOS-C) that can use with W5100S-EVB-Pico. And I try to connect some sensors.

[SENSIRION SHT3X-DIS](https://sensirion.com/products/catalog/?filter_series=370b616d-de4c-469f-a22b-e5e8737481b5)

: Humidity and Temperature Sensor

[InvenSense MPU-6050](https://invensense.tdk.com/products/motion-tracking/6-axis/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](https://github.com/raspberrypi/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.

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.
