ESP-32 with Strain Gauge

Introduction:
The Objective of this homework is to learn how a strain gauge works and to have wireless communitcation between ESP32

Materials and Methods:
Arduino, ESP32 and Strain Gauge


Results:

Task 1: Use the ESP32, HX711 to build a pressure Sensor.


Figure 1: Weight Shown to the Serial Print
The data shown in the video is showing for (g) not (kg). I was using an item that weighted about 60g and the output was 64g so the calibration was good.

Task 2: Send this Data across ESP32s


Figure 2: SerialPrint on Main ESP32 and then Tera Term shows Serial Print of second ESP32



Figure 3: Shows the connection of the 2 ESP32s

The Code for this project is on the server: djlee1/CE432/HW5/ESP32SenderPressure or djlee1/CE432/HW5/ESP32RecieverPressure

Discussion:
This Project was fun to be able to complete. It taught me how strain gauges work and applications that they are useful in. It was good to review the sending of data between two ESP32.
