ZMY20

• Magnetoresistive Sensor
• Without internal magnet ZMY20TA-->Not For New Designs
• Good working design for Parking from Libelium (below, with ZMY20 not-with-internal-magnet, probably with ZMY20M external magnets not needed)

• With internal Magnet ZMY20M-->suggested Digikey
• Sensitivity 5.5mV/V / KA/m = 4.4mV/V / mTesla = 0.44mV/V / Gauss ==> 1.32 mV / Gauss at 3V
• ---- 12V operation ----
• Consumption: 120 mW at 12 V ==> 10 mA at 12 V
• TODO:

Check if 3 V operation is possible

• ZMY20M SOT223 MAGNETIC FIELD SENSOR WITH INTERNAL MAGNET at Digikey $4.8
