Anatomy of the sensor

50kg Capacity

Rated for serious load-sensing, from kitchen scales to bench force meters.

Half-Bridge Design

Pairs with a second gauge or amplifier for a stable, accurate reading.

Resistance Strain Half Bridge Sensor 50kg

Compact Body

Small footprint slips into custom enclosures and tight prototypes.

HX711-Ready

Wires straight into the amplifier setups makers already use.

The problem

Industrial accuracy shouldn't need an industrial order

Proper strain gauges are usually sold in bulk to B2B buyers, leaving hobbyists stuck with unspecified $0.50 sensors of unknown accuracy. This half-bridge sensor is sold as a single, properly rated unit — the same sensing principle used in industrial scales, scaled down to bench-project pricing.

  • 50kg half-bridge rating, stated upfront
  • Sold as a single unit — no bulk minimums
  • Built for scale, force, and weight-sensing projects

From sensor to reading

  1. Step 01

    Mount the sensor

    Fix the half-bridge sensor to your load point or enclosure frame.

  2. Step 02

    Wire to an amplifier

    Connect to an HX711-style amplifier module alongside your microcontroller.

  3. Step 03

    Read the output

    Pull calibrated weight data into your Arduino, Raspberry Pi, or custom board.

Fits your build

Built for maker benches, not factory floors

This sensor is sized and specified for the way makers actually build: breadboards, small enclosures, and microcontroller-driven prototypes. Pair it with your existing HX711-style amplifier and your sensing project moves from idea to working reading.

  • Compact enough for custom enclosures
  • Works alongside common HX711-style amplifiers
  • Suited to scales, force meters, and IoT weight sensing
