A straight bar load cell (strain gauge) that translates up to 5kg of force into an electrical signal. Made from aluminium alloy with four strain gauges in a Wheatstone bridge configuration, it measures electrical resistance changes proportional to the applied load.
Use it to measure object weight, detect weight changes over time, or sense the presence of objects on a surface. Pair with an HX711 amplifier for easy integration with Arduino and other microcontrollers.
Key Features
- 5kg Capacity – Measures force up to 5kg

- M5 Mounting Holes – Two through-holes for secure mounting
Specifications
- Capacity: 5kg
- Material: Aluminium alloy
- Protection: IP65
- Mounting: 2× M5 through-holes
- Wiring: Red (Exc+), Green (Sig+), Black (Exc−), White (Sig−)
Ideal For
- DIY scales and weight measurement projects
- Detecting object presence on a surface

- Arduino and microcontroller-based force sensing
Resources
Jargon buster
Plain-language definitions for the technical terms used above.
- microcontroller
- A microcontroller is a small computer on a chip that runs your program and controls connected inputs and outputs. For this product, it is the part that reads buttons and sensors, drives the display and speaker, and communicates over Bluetooth.
- Strain gauge
- A sensor element that changes resistance when it is stretched or compressed. It is commonly used for measuring force, weight, or bending, and often needs precise differential measurement electronics like this ADC.
