Weight Sensor Wokwi | Simulating Load Cells with Arduino & ESP32

Test Your Weight Measurement Projects Online Before Building Hardware

A Weight Sensor in Wokwi is the perfect way to prototype, test, and simulate your weight measurement projects without needing the actual hardware. Makers, students, and IoT developers use Wokwi to simulate Arduino and ESP32 circuits — and with the help of libraries and custom components, you can experiment with weight sensors, HX711 modules, and load cell calibration directly in the cloud.

At Sensors and Gauges, we provide high-precision weight sensors, load cells, and HX711 amplifier modules that you can integrate once your Wokwi simulation is complete.

Can You Simulate a Weight Sensor in Wokwi?

Yes ✅ — while Wokwi doesn’t have a native load cell component, you can simulate a weight sensor setup by:

  1. Adding an HX711 module (available as a custom library)

  2. Connecting it to an Arduino Uno, Nano, or ESP32 in Wokwi

  3. Using a virtual input or slider to simulate different weight values

  4. Running your Arduino code for calibration and data output

This gives you the ability to test your wiring, libraries, and logic before using physical hardware.

How to Connect a Weight Sensor in Wokwi

Here’s a typical Wokwi simulation setup:

  • Load Cell → Virtual input (simulated via code variables or sliders)

  • HX711 Module → Added as a custom component

  • Arduino Uno / ESP32 → Main controller

Wiring Guide (HX711 to Arduino):

  • DT → Digital Pin 2

  • SCK → Digital Pin 3

  • VCC → 5V

  • GND → GND

Arduino Code in Wokwi (Snippet):


#include "HX711.h" HX711 scale; #define DT 2 #define SCK 3 void setup() { Serial.begin(9600); scale.begin(DT, SCK); scale.set_scale(420.0); // calibration factor scale.tare(); // reset the scale to 0 } void loop() { Serial.print("Weight: "); Serial.print(scale.get_units(), 1); Serial.println(" g"); delay(500); }
