SKU: AF-160

The PS1240 is a compact piezo buzzer for generating beeps, tones, and alerts in electronic projects. Drive it with a 3–30 V peak-to-peak square wave from a timer or microcontroller. It produces its loudest output around 4 kHz but works well across the 2–10 kHz range. For extra volume, use differ...

SKU: SF-COM-13939

A piezo alarm with 16 selectable tone patterns configured via on-board DIP switches. Tone options include continuous, chime, intermittent, warble, and pulsating modes. Capable of producing up to 103 dB(A) at 16 V, making it suitable for audible alarm and alert applications. Key Features 16 Ton...

SKU: AF-1739

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 enclosed housing includes mounting holes for easy attachment to panels, enclosure...

SKU: AF-1536

A breadboard-friendly active buzzer module that produces a loud 2 kHz tone when you apply 3–5V. Unlike a passive piezo element, this buzzer has built-in driver circuitry — no oscillating signal needed, just apply power and it beeps. Key Features Active Buzzer – Built-in oscillator circuit, no ...

SKU: LB-LR0288

A simple 5V active buzzer that generates a tone using its built-in oscillator. Just apply a DC voltage and it sounds — no additional signal generation or driver circuit required. Ideal for adding audible alerts, alarms, or feedback tones to Arduino and microcontroller projects. Key Features Ac...

SKU: SF-COM-27247 · MPN: COM-27247

A compact through-hole speaker that solders directly to your PCB. When you need better audio quality than a piezo buzzer but don't have room for a full-sized speaker, this 30mm unit hits the sweet spot – clear enough for voice prompts and alerts, small enough to fit in tight enclosures. The plas...

SKU: AF-2993

A tri-colour tower light with red, yellow, and green LED segments plus a built-in buzzer, powered by 12V DC. Each light and the buzzer are independently controlled via separate wires, making it easy to indicate machine status, project states, or alert conditions from a microcontroller. The light...

SKU: KI-5336

The Kitronik Smart Air Quality Board provides a complete air monitoring and datalogging solution for the Raspberry Pi Pico. With an onboard BME688 environmental sensor, OLED display, real-time clock support, and MicroPython libraries, it's ready to measure temperature, pressure, humidity, air qua...

SKU: DF-SEN0209

This is an Arduino compatible piezo film vibration sensor. It is made up of flexible piezo film and converter board. The sensor is able to detect vibration, flexibility, impact and touch. The film is a flexible component comprising a 28 µm thick piezoelectric PVDF polymer film with screen-printe...

SKU: LB-LS0038B

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 a small form factor, making it an ideal choice for applications where space is ...

SKU: PR-PIM510

A Raspberry Pi-powered plant monitoring system that tracks moisture levels across up to three pots, alerts you when plants need water, and can even automate watering with optional pumps. The kit centres around the Grow HAT Mini, a compact add-on board with a built-in LCD, buttons, buzzer, and lig...

SKU: AF-1740

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, tones and alerts AND you can use it as a sensor, to detect fast movements like knock...

SKU: AF-5791

The Adafruit STEMMA Piezo Driver Amp uses the PAM8904 switched-capacitor driver to amplify signals for piezo elements at up to 300 kHz. With bridge-tied load (BTL) output and up to 3× voltage multiplication, it can deliver approximately 13 Vpp — much louder than driving a piezo directly from a 3V...

SKU: SF-SEN-09197

A flexible piezo vibration sensor from Measurement Specialties, commonly used for detecting flex, touch, vibration, and shock. The PVDF polymer film generates a small AC voltage (up to ±90 V) when it moves, which can be brought down to ADC-readable levels with a simple resistor divider. This vers...
