A potentiometer is a manually adjustable variable resistor with 3 terminals. Two of the terminals are connected to the opposite ends of a resistive element, and the third terminal connects to a sliding contact, called a wiper, moving over the resistive element.
Industrial Production: Liquid level sensors are used to measure the liquid level in industrial equipment such as boilers, oil tanks, water tanks, chemical reactors, and more. When the liquid level is below or above the safety level, the liquid level sensor can sound an alarm or shut down equipment to ensure production safety.
Buzzer is a crucial component used in various electronic devices, including home appliances, security systems, and automobiles. Industrial factories in Europe and America often require buzzer modules to function in production lines or as part of a warning system.
