A voltage sensor is a device used to measure the electrical potential difference (voltage) between two points in a circuit. It can detect the presence of voltage, and depending on the type, it can give a digital or analog output that reflects the magnitude of the voltage being measured.
Voltage sensors are often used in various applications like:
How it works:
A voltage sensor typically uses components like resistors or capacitors that react to the voltage difference between two points. It then converts this reaction into an output signal (e.g., a voltage or current) that can be read by a microcontroller, indicator, or display.
In simpler terms, think of it like a "voltage detector" that tells you how much electrical pressure (voltage) is available at any given point in a circuit.
Voltage sensors are often used in various applications like:
- Monitoring power systems: In electrical circuits, to ensure safe operation by monitoring voltage levels.
- Protection systems: To trigger alarms or safety mechanisms when voltage levels go above or below a safe range.
- Measurement tools: Used in devices like voltmeters or multimeters to display voltage.
