China Single Point Load Cells Components and Wiring Setup

Blog Article

To successfully use a single point load cell, you need to connect it with supporting components that can read and interpret its low-level signal. The basic components involved include:

A single point load cell (e.g., 1kg to 10kg capacity)

An amplifier module, most commonly the HX711

A microcontroller such as an Arduino, ESP32, or Raspberry Pi

Connecting wires, breadboard, and optionally a power source or battery

The single point load cell typically comes with four wires, each with a specific purpose:

Red: Excitation+ (E+)

Black: Excitation– (E–)

White: Signal– (S–)

Green: Signal+ (S+)

These wires are connected to the HX711 module. The module amplifies the tiny signal from the load cell and converts it into digital values readable by a microcontroller. The HX711 then connects to the microcontroller via digital pins — usually two pins: one for data (DT or DOUT) and one for the clock signal (SCK).

Ensuring correct wiring is essential, as reversed or poor connections can result in inaccurate readings or no output at all. Once everything is wired correctly, you can begin programming the microcontroller to interpret the data from the sensor.
