SmartSens MICROMAG MODULES
All-in-one…
PNI's MicroMag products incorporate 2 or 3 SmartSens magneto-inductive sensors and PNI's MagIC or 11096 ASIC controller on a single PCB, to provide a complete magnetic field sensing solution. The SPI interface provides an output signal which is inherently digital with best-in-class resolution and noise immunity; and, it can be fed directly into a microprocessor, eliminating the need for additional signal processing. Additionally, MicroMag products offer twice the field measurement range of competitive technologies, which allow for superior performance in the presence of magnetic distortions.
…for magnetic field sensing applications
The MicroMag family consists of three models. The MicroMag2 and MicroMag3 are 2- and 3-axis models, respectively, for compassing or other magnetic field sensing applications. The MicroMagIC is a 3-axis product incorporating PNI's MagIC high-speed ASIC controller, and is ideal for applications such as video gaming and remote device control that require high refresh rates. All are available as application kits that include the MicroMag module plus a communication board, cable, and evaluation software.
With a large magnetic field measurement range, high resolution, and digital output, the SmartSens MicroMag products are ideal for product prototyping for high-volume applications, as a complete solution for lower volume OEM applications, as well as research, educational, and hobby use. It is engineered to make designing systems faster and easier than building a magnetic field sensing solution from scratch.
The MicroMag family combines PNI's SmartSens magneto-inductive sensors and a SmartSens ASIC controller in an all-digital module that requires no additional circuitry. The MicroMag product family drastically reduces the time and expense of designing a system from individual components. And because it uses PNI's low power magneto-inductive sensors, its power use is measured in micro-amps.

MicroMag 2 Module
MicroMag 2 Module mounted on a carrier board
The MicroMag 2 Evaluation Kit contains a MicroMag 2 Module mounted on a carrier board, PNI CommBoard, computer interface cable and CD containing manuals and evaluation software. This kit allows the user to quickly evaluate the Sen-XY and MicroMag 2 module in a 2-axis magnetometer or compass application.
MicroMag 3 Module
The MicroMag 3 Evaluation Kit contains a MicroMag 3 Module, PNI CommBoard, computer interface cable and CD containing manuals and evaluation software. This kit allows the user to quickly evaluate the Sen-XY, Sen-Z and MicroMag 3 module in a 3-axis magnetometer or 2-axis compass application.
The PNI CommBoard is an evaluation tool which provides SPI to RS-232 conversion of PNI products and also contains algorithms for calibration, distortion correction and data collection for those products which do not include a controller. The PNI CommBoard with included cable and application software allows the user to be up and testing in a matter of minutes to evaluate PNI's technology reducing the initial development cost and time.
