HMC10XX FAMILY
Simple Circuit Application
12
The circuit in Figure 15 shows a simple magnetic sensor.
This circuit acts as a proximity sensor and will turn on the
LED when a magnet is brought within 0.25 to 0.5 inch of the
sensor. The amplifier acts as a simple comparator and
switches low when the HMC1001 bridge output exceeds

30mV. The magnet must be strong (200 gauss) and have
one of its magnetic poles point along the sensitive direction
of the sensor. This circuit can be used to detect a door open/
closed status or the presence or absence of an item. Figures
16, 17 and 18 show other circuit examples.

Calibrate:
1. Trim R1 for (+V) - (-V) < 30mV
2. Apply signal < 30mV, LED should be off.
3. Apply signal > 30mV, LED should be on.
