Good value component

Solid build quality for the price. You definitely need an amplifier module to read the signal properly. Good addition to my parts kit.

Great for jewelry scale build

Built a small jewelry scale with this. Once calibrated, it gives consistent readings down to the gram. Highly recommend for hobbyists.

Accurate but requires care

The sensor is very sensitive and accurate. Just make sure you mount it correctly on a stable surface, otherwise readings fluctuate.

Perfect for Arduino Projects

I used this load cell to build a custom shipping scale. It paired perfectly with the HX711 amplifier and was easy to calibrate using standard libraries.

5 FAQ

Q: What library do you recommend for calibration?

A: The 'HX711 Arduino Library' by Bogdan Necula is widely used and includes examples for calibration and tare functions.

Q: Is this sensor waterproof for outdoor use?

A: No, this module is not waterproof. It should be used in dry, indoor environments to prevent damage to the electronics.

Q: Do I need an amplifier to use this with Arduino?

A: Yes, the output signal is very small. You will need an amplifier module like the HX711 to interface it with a microcontroller.

Q: What are the wire color functions for this module?

A: Typically, Red and Black are for Excitation (+E and -E), while White and Green are for Signal (+S and -S). Please check the specific datasheet for your batch.

Q: Can this measure weights below 1 gram?

A: While sensitive, this model is rated for 50kg. For sub-gram precision, a lower capacity load cell is recommended for better resolution.
