Load Cell Weight Sensor (1KG / 5KG / 10KG / 20KG) – High Precision Strain Gauge for Arduino & HX711

A high-precision load cell weight sensor designed for accurate force and weight measurement in electronics and IoT projects. Available in 1KG, 5KG, 10KG, and 20KG variants, this sensor uses a strain gauge to convert mechanical force into an electrical signal.

Perfect for use with the HX711 amplifier module (sold separately), this load cell enables precise digital weight readings when paired with Arduino, Raspberry Pi, ESP32, and other microcontrollers.

Key features

• High-accuracy strain gauge load cell
• Multiple capacity options: 1KG, 5KG, 10KG, 20KG
• Stable and repeatable measurements
• Compact aluminium body for durability
• Ideal for DIY weighing scales and force measurement
• Compatible with HX711 ADC module for easy interfacing

How it works

The load cell deforms slightly under weight, changing the resistance of its internal strain gauges. This small change in voltage is amplified using an HX711 module, allowing your microcontroller to measure weight accurately.

Wiring

• Red (E+) – Excitation positive (power +)
• Black (E-) – Excitation negative (ground)
• Green (S+) – Signal positive
• White (S-) – Signal negative

Note: This load cell requires an HX711 amplifier module to interface with microcontrollers. The HX711 is sold separately.
