Arduino Hall Effect Sensor A503

It features a huge voltage operating range of 3.5V to 24V, and an operating temperature range of -40°C to 85°C. The output signal is open-drain type, so for regular microcontroller applications you have to use a pull-up resistor tied between a pull-up voltage and the device output.
