KY-025 Reed Switch Sensor

616 views

The KY-025 Reed Switch Sensor is a versatile electronic component used for detecting the presence or absence of a magnetic field. This sensor module consists of a reed switch enclosed in a protective housing. When a magnetic field is applied to the proximity of the sensor, the reed switch inside it is triggered, causing a change in its electrical state. This makes the KY-025 Reed Switch Sensor ideal for various applications such as magnetic door/window sensors, security systems, proximity detection, and automation projects. With its compact size and reliable performance, this sensor module offers a convenient and effective solution for detecting magnetic fields and enabling interaction between the physical and digital worlds.
