Load Sensor – 50kg
50kg-class load sensor for weighing and force-measurement prototypes. Its low-level bridge signal normally requires a compatible load-cell amplifier or ADC such as an HX711, careful mechanical mounting and calibration with known weights. Confirm whether the planned scale needs multiple half-bridge sensors before ordering.

50kg Load Sensor Price in Pakistan
This 50kg-class load sensor is intended for digital-scale, force-measurement and Arduino-compatible weighing prototypes. The sensing element produces a very small electrical change when mechanically loaded, so it normally requires a suitable bridge arrangement and a load-cell amplifier or ADC such as an HX711.
Important integration requirements
- Mount the sensor in the correct load direction without twisting the body.
- Use a stable excitation supply and compatible low-noise amplifier.
- Confirm the wire arrangement before applying power.
- Calibrate the completed assembly with known weights.
- Do not exceed the rated mechanical load.
Many bathroom-scale systems use several three-wire half-bridge sensors rather than one sensor alone. Check whether the intended design requires four sensors, a combinator board and an HX711 module. Mechanical mounting, force distribution and calibration affect the final accuracy as much as the electronic circuit.
For controller-side processing, pair a compatible load-cell amplifier with an Arduino UNO R3 and calibrate the complete mechanical assembly.

Frequently Asked Questions
Does a load sensor connect directly to an Arduino analog pin?
A small load-cell signal normally needs an instrumentation amplifier or ADC module such as an HX711 before a microcontroller can read it reliably.
Does the load sensor require calibration?
Yes. Calibrate the completed mechanical assembly with known weights because mounting and load direction affect the result.
Can one sensor make a complete 50kg bathroom scale?
Many body-scale designs combine multiple half-bridge sensors. Confirm the sensor wiring and required mechanical arrangement before building the full scale.
Why is an HX711 commonly used with a load sensor?
A load cell produces a very small differential signal. An HX711 or similar load-cell ADC amplifies and digitises that signal for a microcontroller.
Does mounting affect load-cell accuracy?
Yes. Load direction, force distribution, twisting, fixture stiffness and mechanical preload can all affect the measured result.

Microphone Amplifier – MAX9814 w/ Auto Gain Control
- The default ‘max gain’ is 60dB, but can be set to 40dB or 50dB by jumpering the Gain pin to VCC or ground.
- You can change the Attack/Release ratio, from the default 1:4000 to 1:2000 or 1:500.
- The ouput from the amp is about 2Vpp max on a 1.25V DC bias, so it can be easily used with any Analog/Digital converter that is up to 3.3V input. If you want to pipe it into a Line Input, just use a 1uF blocking capacitor in series.

Force Sensitive Resistor 0.5 INCH FSR
Thin 0.5-inch force-sensitive resistor for detecting relative touch and pressure in Arduino-compatible controls, robotics and interface prototypes. Resistance decreases as force is applied to the active circular area. Use a voltage-divider circuit and application-specific calibration; this sensor is not a precision weighing load cell.
