The YZC-131 1kg weighing load cell sensor is a straight-bar-style sensor that measures pressure or force and converts it into a small electrical signal. It is widely used in electronic kitchen scales, balance material scales, and other small-scale measurement projects. This sensor is not a complete weighing system on its own and requires additional components, most commonly an HX711 amplifier module and a microcontroller, to process and convert the output signal
The term "P 8406 amp module" is likely a typo for the PAM8406 amplifier module, a popular component for DIY electronics projects. It is a compact, stereo, Class-D audio amplifier that is known for its high efficiency and low-cost design
