The HMC1021Z and HMC1021S 1-Axis and HMC1022 2-Axis magnetic sensors offer a resolution of 85 µGauss. These sensors offer small size, low power, high sensitivity, low cost and versatility for high volume OEM applications. Additionally, these devices include Honeywell's patented on-chip “Set/Reset” & “Offset” straps which can be used to eliminate the effects of stray magnetic fields, temperature drift, amplifier offsets and drift. These sensors are the best solution for nulling hard iron offset such as in automotive compassing applications.
