Interface: SPI (4-wire)
It is developed with an innovative design that combines the integration of the Raspberry Pi 4 Model B with the Raspberry Pi Keyboard
and other motor-driven machinery
To measure the weight and load of any object we use strain gauges but the problem with using standalone strain gauges is that they are fragile and are easily bent and break if not used in a proper enclosure

500K Cermet(Pack of 5) Gas Sensor Interface: SPI (4-wire)500K ohm Cermet Preset Potentiometer (Pack of 5) Cermet preset is a compact variable resistor and PCB mountable with 3 terminal pins. The voltage between the terminal varies as the preset is rotated. The Variable resistors are used for variating voltage as per the need in a circuit. The outer two pins are connected to Vcc and 0V, and center pin outputs a variable voltage between 0v and Vcc as the rotary cermet is rotated. Applications: Can be used as
