Piezo elements come in handy when you need to detect vibration or a knock. You can use these for tap or knock sensors pretty easily by reading the voltage on the output. They can also be used for a very small audio transducer such as a buzzer. Learn More

This basic piezo sensor from Measurement Specialties is often used for flex, touch, vibration and shock measurements. A small AC and large voltage (up to +/-90V) is created when the film moves back and forth. A simple resistor should get the voltage down to ADC levels. Can also be used for impact sensing or a flexible switch. Learn More

This AT407 basic tilt switch can easily be used to detect orientation. Inside the can are a pair of balls that make contact with the pins when the case is upright. Tilt the case over and the balls don’t touch, thus not making a connection. Learn More
