About this item

The SparkFun SEN-13879 Load Cell Amplifier is a dedicated breakout board featuring the HX711 chip, designed specifically for amplifying and converting low-level signals from load cells or strain gauges into readable digital output. Load cells produce tiny voltage changes proportional to the force or weight applied, which require precise amplification and analog-to-digital conversion to be interpreted by microcontrollers like Arduino or Raspberry Pi. The HX711 chip is widely recognized for its high precision and integrated 24-bit ADC, making it a popular choice in weighing scales and force measurement projects. This amplifier board simplifies the process by providing a ready-to-use interface, including convenient screw terminals for easy load cell connection and header pins for microcontroller integration. It supports two input channels, allowing connection of multiple sensors or differential inputs, with programmable gain settings (128 or 64) for enhanced sensitivity. Ideal for hobbyists, engineers, and researchers, the SEN-13879 enables accurate weight or force readings in applications ranging from DIY digital scales to industrial monitoring systems. Its low noise and high resolution ensure stable measurements even in noisy environments. Compact and robust, this amplifier is a key component for any project involving load cells.
