Essential component for weight projects

If you are building anything that requires weight measurement, this is the go-to module. The 24-bit ADC makes a huge difference compared to analog sensors.

Highly sensitive and reliable

I used the 5kg version for a coffee bean dispenser. The resolution is impressive, detecting even single beans dropping. No noise issues observed.

Good value but wiring needs care

The sensor is accurate once calibrated. Just be careful with the wire colors as they can vary slightly from standard load cells. Overall a great buy for the price.

Perfect for DIY Scales

This module works flawlessly with my Arduino project. The HX711 chip provides very stable readings, and the library support is excellent. Setup took less than 10 minutes.

Works well after calibration

Took some time to get the calibration weights right, but once done, it holds the value steady. The small form factor fits easily into tight enclosures.

Great for robotics applications

Using this on a robot arm gripper to measure object weight. It responds quickly and integrates perfectly with the ESP32. Highly recommended.

5 FAQ

Q: What is the maximum cable length recommended between the load cell and the module?

A: For best signal integrity, we recommend keeping the cable length under 1 meter. If longer distances are required, shielded cables should be used to prevent interference.

Q: Does this come with example code for Arduino?

A: While the package includes hardware only, there are many open-source libraries available on GitHub, such as 'HX711-Arduino-Library', which provide ready-to-use examples.

Q: Can this module be used directly with a 3.3V microcontroller like the ESP32?

A: Yes, the HX711 module operates within a voltage range of 2.6V to 5.5V, making it fully compatible with 3.3V logic systems like the ESP32.

Q: How do I switch between 10Hz and 80Hz sampling rates?

A: The sampling rate is selected by the state of the PD_SCK pin when the chip wakes up from power-down. Pulling the pin low selects 10Hz, while pulling it high selects 80Hz.

Q: Is the 10kg load cell suitable for weighing liquids in a container?

A: Yes, provided the total weight of the container plus the liquid does not exceed 10kg. You will need to tare the weight of the empty container in your code.
