Excellent integration with ESP32

Works perfectly with ESP32 as well. The update rate is fast enough for real-time monitoring. Highly recommend for anyone building smart scales.

Solid performance

Does exactly what it says. The display brightness is adjustable which is a nice touch. Only wish it came with a longer connector cable.

Stable readings every time

I tested this with a 5kg load cell and the noise level is incredibly low. Great for precision weighing applications in home automation projects.

Good value, minor wiring confusion

The sensor is accurate and stable once connected. The pinout diagram on the back could be clearer, but online resources helped me figure it out quickly.

5 FAQ

Q: What is the maximum wire length recommended for the load cell?

A: For best accuracy and minimal signal interference, we recommend keeping the load cell wires under 1 meter. If longer distances are needed, shielded cables are strongly advised.

Q: How do I change the sampling rate from 10Hz to 80Hz?

A: The sampling rate is selected by the state of the PD_SCK pin when the module powers up. Please refer to the datasheet included in the download section for the specific wiring configuration to switch rates.

Q: Does this come with the load cell or just the module?

A: This package includes the HX711 module and the digital display unit. Load cells (1KG/5KG/10KG/20KG) must be purchased separately unless specified in a bundle option.

Q: Can this module support a 50kg load cell?

A: While the HX711 chip itself can handle various load cells, this specific kit is optimized and calibrated for 1KG to 20KG ranges. For 50KG, you may need to adjust gain settings significantly or check compatibility with your specific cell.

Q: Is the library compatible with Raspberry Pi?

A: Yes, there are several Python libraries available for Raspberry Pi that support the HX711 interface via GPIO pins. You will need to connect the DT and SCK pins to appropriate GPIO ports.
