This load sensor, sometimes called a strain gauge, is the same one found in digital bathroom scales. This sensor can measure up to about 50kg. This weight sensor is suitable for electronic balance and other high-accuracy electronic weighing devices. and you will get it with HX711 load cell amplifier which reads the sensor output and amplify it to the MCU to be used
