Additional Details

The HAL1562SU-A typically has a sensitivity of several mV/mT (millivolts per millitesla). It operates over a temperature range of -40°C to +150°C, making it suitable for harsh environments. The output voltage is usually centered around half the supply voltage when no magnetic field is present. An external amplifier circuit can be used to amplify the output signal and improve the signal-to-noise ratio. The sensor is often used with a microcontroller for signal processing and data acquisition.
