### Electronic scale display module, for HX711, load cell
- Page: https://sigmanortec.ro/en/electronic-scale-display-module-for-hx711-load-cell
- Details: https://sigmanortec.ro/en/llms/p/1811.md
- Price: 25.89 RON
- Availability: In stock; 1-2 zile
- Reference: 9699 · EAN: 5940841723674

Digital display for weighing with HX711, takes the signal from the HX711 module connected to the load cell and directly displays the weight on the 4-digit LED tube, up to 9999 g. Compatible with common sensors 1-20 kg, optimal for 5-10 kg, 3-5.5 V power supply and memory for maintaining calibration after power off.
The load reading module for the HX711 AD is a high precision weight measuring instrument with a distinct digital display capability.
The module requires connection to the HX711 module, which in turn is connected to the load cell. It just displays the weight based on the signal reading received from the HX711.
