Piezo electric 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...
Whether used as a vibration sensor, a flexible switch, or a frequency response device, piezo film is an interesting sensor to interface with any microcontrollers.
Features:
Wide range of applications
Thin polymer film laminate with 2 crimped contacts
Easy interface with any&..
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 se..
This is a low-cost cantilever-type vibration sensor loaded by a mass to offer high sensitivity at low frequencies. Useful for detecting vibration and 'tap' inputs from a user. A small AC and large voltage (up to +/-90V) is created when the film moves back an forth. A simple resistor should g..
Reed is a kind of passive electronic switching component with contacts with a simple structure, small size and easy to control. It consists of a sealed glass envelope where there are two ferrous elastic reeds and is filled with inert gas called rhodium.A reed switch is a sensor that closes circuit i..
This is a cost-effective and highly functional hall-effect sensor. Very easy to interface with all microcontrollers.
This is an integrated Hall effect latched sensor. That's nice but what does it do? Holding a magnet near the sensor will cause the output pin to toggle. This makes for a robust pre..
The VTI SCP1000 is an absolute pressure sensor which can detect atmospheric pressure from 30-120 kPa. The pressure data is internally calibrated and temperature compensated. The SCP1000 also provides temperature data and has 4 measurement modes as well as standby and power down mode.
All that is..
This Incremental Rotary Encoder provides 16 pulses per revolution via 2-bit quadrature outputs. 3-pin SIP header provides easy breadboard connection. This encoder rotates continuously through 360 degrees and provides detent to hold position. Used with a push button this encoder could provide a compl..
