SparkFun Hall-Effect Sensor - AH1815 (Non-Latching)

Description The AH1815 is an integrated Hall-Effect non-latched sensor Holding a magnet near the sensor will cause the output pin to toggle Designed for portable and battery powered consumer equipment The SparkFun Hall-Effect Sensor - AH1815 (Non-Latching) is an integrated Hall-Effect non-latched sensor. That’s nice but what does it do? Holding a magnet near the sensor will cause the output pin to toggle. This makes for a robust presence sensor. A reed sensor also works nicely, but can be limited by the glass encapsulation and size. A Hall-Effect sensor is much smaller, but can handle less current than a reed switch. The AH1815 is a low-sensitivity, micro-power Omnipolar Hall effect switch IC, designed for portable and battery powered consumer equipment for home appliance and industrial applications such as smart-meter magnetic-tamper detection. Based on two sensitive Hall effect plates and a chopper-stabilized architecture, the AH1815 provides a reliable solution over t
