Description
MINIMUM TECH FEATURES
- Linear Hall Effect sensor
- Analog output voltage
- Operates on 3.0V – 6.5V supply
- High-sensitivity bipolar Hall element
- Fast response time
- Compatible with Arduino, ESP32, ESP8266, AVR, PIC, Raspberry Pi
- Standard TO-92 package
DESCRIPTION
- The AH49E is a linear Hall Effect sensor that converts magnetic field strength into a proportional analog voltage.
- It identifies changes in magnetic flux density and generates an output based on the magnetic field’s direction and strength.
- Designed for high-sensitivity and low-noise operation, providing precise magnetic measurement.
- Useful for contactless position sensing, speed detection, current measurement, and proximity detection.
- The built-in voltage regulator and temperature compensation ensure stable performance across varying environments.
- Widely used in consumer electronics, automotive systems, robotics, and instrumentation.
- Supports continuous analog output, making it ideal for microcontroller ADC inputs.
