PIR movement alarm - Micro:bit
网页A wireless intruder alarm using a movement detector. How it works. PIR (passive infra red) sensors are commonly used in burglar alarms and office lighting systems to detect movement. You can connect one to a micro:bit's pins (see diagram) to trigger an alarm when movement is detected.
Simple door alarm - Micro:bit
网页In this project you'll make a door alarm that works just like a real door sensor in a home security system. Your micro:bit has a built-in compass sensor called a magnetometer. You can use it to measure the Earth’s magnetic field as a compass - or to sense how strong magnetic fields are much closer to home!
Pressure switch alarm - Micro:bit
网页What is it? Create a wireless intruder alarm that will warn you when someone steps on a home-made pressure sensor. How it works. Flash the sensor program onto a micro:bit. Make a pressure input switch out of cardboard and tin foil like in the picture. Fold it over and place it under a rug or carpet.
Create a Light-sensitive Alarm with micro:bit - Little Bird
网页In this guide, we will learn to differentiate between the two, then connect a passive buzzer module to the micro:bit and get it to play a song and change its bpm with a button press. A light dependent resistor will also be added to the circuit, to create an alarm clock that automatically rings when it gets bright.
