KY-035 Hall Magnetic Sensor

KY-035 Hall Magnetic Sensor Module – Product Description The KY-035 Hall Magnetic Sensor Module is a linear Hall-effect sensor designed to detect and measure the strength and polarity of magnetic fields. It is based on the AH49E Hall-effect sensor, which produces an analog voltage output proportional to the magnetic field intensity. When no magnetic field is present, the output voltage remains approximately half of the supply voltage. As the magnetic field changes, the output voltage increases or decreases depending on the magnet's polarity. Operating on 3.3V to 5V DC, the KY-035 is fully compatible with Arduino, ESP32, ESP8266, Raspberry Pi, and other microcontroller platforms. Its analog output enables accurate magnetic field measurement, making it suitable for position sensing, speed detection, motor control, and automation applications. Features Linear Hall-effect sensor for magnetic field detection Analog output proportional to magnetic field strength Detects both the strength and polarity of magnetic fields Operating voltage: 3.3V–5V DC Low power consumption and stable performance Compatible with Arduino, ESP32, ESP8266, Raspberry Pi, and other development boards Applications Magnetic field measurement Position and proximity sensing Motor speed and rotation detection Industrial automation and control systems Robotics and embedded system projects Educational electronics experiments The KY-035 Hall Magnetic Sensor Module provides a reliable and cost-effective solution for measuring magnetic fields with high precision. Its analog output and simple interface make it an excellent choice for embedded systems, robotics, automation, and educational projects that require accurate magnetic field sensing.
