The foundation of PNI's ready-to-integrate® sensor modules, the SmartSens family of magneto-inductive (MI) sensors and ASICs delivers best-in-class magnetic field sensing resolution and repeatability — while using less than half the power of magneto-resistive (MR) sensors. A SmartSens circuit generally consists of 1 to 3 SmartSens MI sensors driven by a SmartSens ASIC in an LR circuit. The output from a SmartSens sensor is inherently digital and can be fed directly into a microprocessor, eliminating the need for signal conditioning or an analog/digital interface. And since the SmartSens sensor works in the frequency domain, resolution and noise are established cleanly by the number of period counts. Optimized for use in game controllers, solid-state navigation devices, and handheld devices with integrated compassing functions, SmartSens sensors are ideal wherever power is at a premium and performance can't be compromised.
The MicroMag product line of magnetic field sensing modules integrates PNI's SmartSens magneto-inductive sensors and ASICs with additional surface mount components onto a single PCB — so they can be designed into research and demo units or product prototypes with little to no engineering cost. They are ideal for use in educational, hobbyist, and other low-volume applications, as well for design and prototyping for high-volume applications.
