This G123-08 module is a magnetic sensor. It has a reed switch and an LM393 chip. When a magnet is near, the LM393 gives a clear digital signal. This makes it good for Arduino projects and other DIY electronics that need to sense magnets. Features and Benefits
- LM393 chip – It cleans up the signal from the reed switch. This gives you a steady digital output without signal bouncing.
- Two output pins – It has a digital out (DO) for simple on/off signals. It also has an analog out (AO) for more detailed readings.
- Adjustable setting – A small knob on the board lets you change the distance. This controls how far away a magnet can be to trigger the switch.
- Mounting hole – The board has a pre-drilled hole. This helps you attach it securely to a case or project frame. Applications
- Home security – Use it as a magnetic contact sensor. You can build a simple alarm for doors or windows.
- Liquid level checks – Attach a magnet to a float in a non-metal tank. It can tell you when the water level changes.
- Robots and machines – It can work as a limit switch or position sensor. It confirms when a moving part has reached its spot.
What It Is
This is a Reed Switch Module, designed for use in Arduino DIY Electronics Kits. It functions as a resistance sensor, detecting proximity. The module model is G123-08 LM393. As a proximity sensor, it operates by detecting the presence or absence of an object without physical contact. This type of electronics module is commonly employed in various DIY projects where non-contact detection is required.
Key Uses & Applications
The Reed Switch Module is suitable for a range of applications within Arduino DIY Electronics Kits. Its primary function as a proximity sensor allows for the detection of objects at a close range. This can be useful for creating automatic switching systems, counting mechanisms, or security systems. For example, it can be used to detect when a door or window is open or closed, or to sense the rotation of a wheel in a homemade speedometer.
How to Choose
When selecting a proximity sensor, consider the specific requirements of your project. This Reed Switch Module is compatible with Arduino DIY Kits. If you need to test a proximity sensor, you would typically use a multimeter to check for changes in resistance or voltage output when an object is brought close to the sensor. For industrial applications, you might consider barrel sensors or optical sensors, depending on the required detection range and environmental conditions.

A: Yes, it's designed for that. It operates on a voltage range of 3.3V to 5V and provides a simple digital high/low signal, making it easy to connect to the digital pins of most microcontrollers.. Q: What's the advantage of using this module over a simple reed switch? A: This module includes an LM393 comparator circuit. This cleans up the signal from the reed switch, giving you a stable, bounce-free digital output that's much easier for a microcontroller to read accurately.. Q: What kind of output signal does it produce? A: It has a digital output. When a magnet is near the sensor, the module outputs a low signal (0); when the magnet is away, it outputs a high signal (1).. Q: How far away can the magnet be to trigger the switch? A: The detection distance depends on the strength of your magnet. Generally, a small neodymium magnet will trigger it from a few millimeters away, which is typical for these types of sensors.. Q: I'm buying the 5-pack. What happens if one of them is faulty? A: We check our components, but issues can happen. If you find a dead-on-arrival module in your pack, let us know and we'll happily send a replacement for the faulty unit..
