3.5-5.5V Standard Active Buzzer Module For Arduino
A Standard Active Alarm Module for Arduino is an audio signaling device, which may be mechanical, electromechanical, or piezoelectric. This PCB Mounted Active Buzzer Module can produce a range of sound tones depending on the input frequency, i.e it can generate tones between 1.5 to 2.5 kHz by switching it on and off at different frequencies either using delays or PWM.An active buzzer rings out as long as it is electrified. Compared with a passive buzzer, it is a bit expensive but easier to control. Typical uses of buzzers include alarm devices, timers, and confirmation of user input such as a mouse click or keystroke.This module is ideally suited to adding noise to your project and is compatible with a pin pitch of 2.54mm while functioning with microcontrollers such as the Arduino. This module lets you respond to programmatic changes with a lovely annoying buzzer that can be altered over a range of frequencies to ensure maximum irritation. To operate the I/O pin must receive a square wave to trigger the buzzer. This can be produced within all popular microcontrollers.Specification:- Working voltage: 3.5-5.5V
- Working current: <25mA
- PCB Dimension: 1.85 x 1.5 cm (L x W)
Feature:
- An active buzzer with a concussion internal source- so long as it will be called an energized
- The program easy to control- SCM can let a high-low sound- while passive buzzer did not.
- The Transistor drive module uses 8550
- With fixed bolt hole- easy installation- 2.6mm aperture.

PIR Motion Detector Sensor Module
The HC-SR501 PIR Motion Detector Sensor Module is a pyroelectric device that detects motion by measuring changes in the infrared levels emitted by surrounding objects. This motion can be detected by checking for a high signal on a single I/O pin.
The module has an onboard pyroelectric sensor, conditioning circuitry, and a dome-shaped Fresnel lens. It has a delay time adjustment Potentiometer and sensitivity adjustment Potentiometer.
It is used to sense the movement of people, animals, or other objects. They are commonly used in burglar alarms and automatically-activated lighting systems. Compatible with ARDUINO, RASPBERRY PI, AVR, PIC, 8051, etc.
Features:
- Compact size
- Infrared sensor: dual-element, low noise, high sensitivity
- Blockade time: 2.5s (Default)
- Infrared Sensor with Control Circuit Board
- The Sensitivity and Holding Time Can be Adjusted
- Sensitive Setting: Turn to Right, Distance Increases (About 7M); Turn to Left, Distance Reduce (About 3M)
- Time Setting: Turn to Right, Time Increases (About 200S); Turn to Left, Time Reduce (About 5S).
