HMR2300 Analog Product Digital Magnetometer To Detect The Strength And Direction Of An Incident Magnetic Field
The AVIC CMR2300 is a three-axis smart digital magnetometer to detect the strength and direction of an incident magnetic field. The three of AVIC’s magneto-resistive sensors are oriented in orthogonal directions to measure the X, Y and Z vector components of a magnetic field. These sensor outputs are converted to 16-bit digital values using an internal delta-sigma A/D converter. An onboard EEPROM stores the magnetometer’s configuration for consistent operation. The data output is serial full-duplex RS-232 or half-duplex RS-485 with 9600 or 19,200 data rates. A RS-232 development kit version is available that includes a windows compatible demo program, interface cable, AC adapter, and carrying case.
