To interface reed switch with Arduino we need to build a voltage divider circuit as shown in the figure below. Vo is +5V when the switch is open and 0V when the switch is closed. We are using a ...

The Reed Switch Module project demonstrates how to detect the presence of a magnetic field using a reed switch with an Arduino Mega. When a magnet is close to the reed switch, it closes the circuit, ...

When reed switch is opened, pin 2 of Arduino goes high with the help of the pull-up resistor R2, and the alert signal is available through the piezo-speaker PZ1 (not an active piezo-buzzer). At the ...

Initially, when the door is closed, the magnet on the door is close to the reed switch (normally-open type) on the door frame and hence the reed switch is closed. So pin 2 of Arduino is ‘high.’ When ...

Then connect the Arduino, via USB to the computer on which the web server is running. Also mount the magnetic reed switch on the door/drawer/anything that can be open/closed. Place the Python script, ...

They are basically like a small reed switch, and when a magnetic field is around, the output voltage will vary according to the magnetic flux. Hall effect sensors are used in BLDC applications because ...

Littelfuse, Inc. has released the MACD-14 and MASM-14 Series, a high-precision extension of its reed switch product line.
