Magnetic Reed Switch Sensor Module – Frequently Asked Questions


What is a Reed Switch Sensor Module?
A Reed Switch Sensor Module detects magnetic fields using a reed switch that closes or opens the circuit. It outputs a digital signal (0 or 1) based on the presence of a magnet.
How does the Reed Switch Sensor work with Arduino?
Connect the sensor’s OUT pin to a digital input pin of an Arduino. When a magnet is near the reed switch, the output becomes LOW (0); otherwise, it remains HIGH (1).
What is the operating voltage of this sensor?
The module 
operates with a supply voltage between 3.3V and 5V, making it compatible with both 3.3V and 5V logic systems.
What type of output does the sensor provide?
It provides a digital output:
  • LOW (0) when a magnetic field is present
  • HIGH (1) when no field is present
Where can this reed switch sensor be used?
Common uses include:
• Door/window sensors
• Alarm and security systems
• Smart appliances
• Liquid/gas/electricity meters
• Robotics and automation projects
Is the sensor suitable for outdoor use?
This sensor is not weatherproof by default. For outdoor applications, use a waterproof enclosure for protection.
How to test if a Reed Switch Sensor is working?
Connect power (3.3V–5V) and monitor the output. Bring a magnet close to the sensor and observe the onboard output LED or measure voltage changes at the output pin.
Can the sensitivity be adjusted?
Some modules have an onboard potentiometer to fine-tune sensitivity. If available, rotate it gently to change magnetic field detection response.
What is the module’s size?
The PCB measures 31.1mm x 14.5mm, allowing it to fit easily into compact or embedded systems.
