The Buzzer Piezo 20mm is a compact and efficient sound-producing device that is perfect for a variety of electronic projects. With its 20mm diameter, this piezo buzzer is designed to deliver clear and audible sound in...

SKU: LB-LR0309-54 | Brand: Little Bird

This is a ball tilt switch. When the switch is vertical the switch is ON. When put horizontal the switch is OFF.   All materials are manufactured using environmentally friendly raw materials, in line with ROHS ...

SKU: AF-1739 | Brand: Adafruit

This large enclosed piezo element (30 mm diameter) converts vibration to voltage and voltage to vibration, making it useful both as a buzzer for generating tones and as a sensor for detecting knocks and impacts. The e...

SKU: AF-2831 | Brand: Adafruit

This Photo Transistor Light Sensor is a simple sensor that detects ambient light. It's kind of the opposite of an LED - when light hits the little chip inside, it induces current to flow from the long pin...

SKU: AF-1740 | Brand: Adafruit

This small (14mm diameter) piezo element is nicely enclosed so you can attach easily. Piezo elements convert vibration to voltage or voltage to vibration. That means you can use this as a buzzer for making beeps, tone...

SKU: LB-LS1216 | Brand: Little Bird

This sensor is composed of an infrared emitter on one upright and a shielded infrared detector on the other. By emitting a beam of infrared light from one upright to the other, the sensor can detect when an object pas...

SKU: SF-SEN-00246 | Brand: SparkFun

This sensor uses an infrared emitted diode combined with an infrared phototransistor to detect the reflected infrared signal. Ideal for sensing black-to-white transitions or can be used to detect nearby objects (.5-1cm).

SKU: SF-SEN-09196 | Brand: SparkFun

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...

SKU: SF-COM-08635 | Brand: SparkFun

Small electret microphone. Useful in acoustic and audio applications. Documents: Datasheet Example Audio LED control project by Adam Greig

SKU: LB-LS0633 | Brand: Little Bird

A pack of 50 through-hole photoresistors (light-dependent resistors / LDRs) with a 5 mm diameter sensing element. These components change their resistance based on the amount of light hitting the sensor — resistance d...

SKU: AF-1767 | Brand: Adafruit

A low-sensitivity, non-directional vibration switch that acts as a simple motion detector. Inside, a stiff spring is coiled around a central metal pin — when the switch is shaken or moved with enough force, the spring...

SKU: AF-1935 | Brand: Adafruit

That's one tiny microphone! At about the size of a mature aphid, this wired Electret Microphone is perfect for your FONA. This microphone's very similar to our PCB-mount Elecret Microphone but is significantly sma...
