HX711 Load Cell Amplifier Breakout CenryKay 24bit AD Converter 10pcs

Description

Product Overview

The HX711 Load Cell Amplifier Breakout by CenryKay is engineered for precision weight measurement across a broad spectrum of applications. At its core lies the industry‑standard HX711 24‑bit analog‑to‑digital converter, a single‑chip solution that delivers high resolution and low noise performance. The module features dual analog inputs, allowing users to connect one or two load cells simultaneously, and includes an integrated programmable gain amplifier (PGA) that can be set to 32, 64, or 128 times gain, adapting to a wide range of sensor sensitivities.

Physically, the breakout board measures 9.13 × 4.69 × 0.67 inches and weighs only 3.21 ounces, making it compact enough for tight enclosures while still providing ample space for wiring and mounting. The board is fabricated from a high‑quality FR‑4 substrate with gold‑plated pins, ensuring reliable electrical contact and resistance to corrosion. Power requirements are modest, operating from a 2.6 V to 5.5 V supply, which aligns perfectly with typical Arduino and other 5 V microcontroller platforms.

Usage

This amplifier module shines in environments where accurate weight data is critical. Hobbyists building kitchen scales can pair the HX711 with a strain‑gauge load cell to achieve gram‑level precision, while engineers designing industrial process control systems can rely on its stability for monitoring material flow or batch weights. The 10‑piece kit includes ten identical modules, enabling rapid prototyping of multiple sensor channels or providing spares for field deployments.

Because the HX711 communicates via a simple two‑wire serial interface (PD_SCK and DOUT), integration with popular development boards such as Arduino Uno, Nano, Mega, and even ESP32 is straightforward. Users can employ the widely available HX711 Arduino library to read raw data, apply calibration factors, and convert the output into meaningful weight units. The module’s low power consumption also makes it suitable for battery‑operated devices, such as portable weighing stations or handheld inspection tools.

In educational settings, the breakout serves as a hands‑on teaching tool for students learning about sensor interfacing, signal conditioning, and digital conversion. Its clear labeling and robust pin layout reduce the learning curve, allowing learners to focus on experiment design rather than troubleshooting hardware connections.

FAQ

What type of load cells are compatible with the HX711 module?

Any strain‑gauge load cell that outputs a differential voltage in the millivolt range can be connected. Common choices include 1 kg, 5 kg, and 10 kg load cells used in kitchen scales and industrial weighing systems.

How do I calibrate the sensor for accurate weight readings?

Calibration involves applying a known weight to the load cell, reading the raw ADC value, and calculating a scale factor. The provided Arduino library includes a simple calibration routine that stores the factor in EEPROM for persistent use.

Can the module operate on a 3.3 V supply?

Yes, the HX711 operates from 2.6 V to 5.5 V, making it compatible with 3.3 V microcontrollers such as the ESP32 or certain Arduino variants. Ensure that the reference voltage matches the logic level of your host board.

Is the module suitable for high‑frequency sampling?

The HX711 supports two data rates: 10 samples per second (SPS) and 80 SPS. For most weighing applications, 10 SPS provides sufficient stability, while 80 SPS can be used for faster response when needed.

What warranty and after‑sales service does CenryKay provide?

CenryKay offers a 30‑day return window and a one‑year limited warranty covering manufacturing defects. Technical assistance is available via email and phone, with response times typically within 24 hours.
