The Ky 021 Datasheet provides critical information for anyone working with the Ky-021 mini magnetic reed switch module. This seemingly simple component plays a significant role in various electronic projects, and understanding its specifications is crucial for successful implementation. The Ky 021 Datasheet is your key to harnessing the full potential of this versatile sensor.
Decoding the Ky 021 Datasheet: What You Need to Know
The Ky 021 Datasheet serves as a comprehensive guide, outlining the module’s electrical characteristics, physical dimensions, and operational parameters. It essentially breaks down everything you need to know to integrate the module into your circuit. This data is indispensable for engineers, hobbyists, and students alike, ensuring that the component is used within its safe operating range. Here’s a quick breakdown of what you might find:
- Operating Voltage: Typically around 3.3V to 5V
- Digital Output: HIGH when no magnetic field is present, LOW when a magnetic field is detected.
- Compact Size: Allows for easy integration into tight spaces.
The datasheet details how the Ky-021 module functions. At its core, it uses a reed switch, a simple electrical switch operated by an applied magnetic field. When a magnet is brought near the reed switch, the two ferrous reeds inside the glass envelope are drawn together, completing the circuit. This change in the circuit is then processed by the onboard electronics and presented as a digital output signal, ready to be read by a microcontroller or other digital device. Here’s how it generally works in practice:
- The Ky-021 module is connected to a power source (3.3V or 5V).
- When a magnet approaches the reed switch, it closes.
- The module’s circuitry detects the closed switch.
- The digital output pin switches to a LOW state.
- When the magnet is removed, the reed switch opens, and the output returns to HIGH.
Understanding the Ky 021 Datasheet allows you to make informed decisions about circuit design, component selection, and troubleshooting. For example, knowing the operating voltage range prevents you from damaging the module by applying too much voltage. Knowing the sensitivity characteristics allows you to correctly place the magnet for proper function of the sensor. Here is a simple representation of the voltage:
| Parameter | Value |
|---|---|
| Operating Voltage | 3.3V - 5V |
