Mikroelektronika MIKROE-3274 HMC1501 Magnetic Displacement Sensor SPI 3.3V 5V

Technical description of the product (MIKROE-3274):

MIKROE-3274 HMC1501 a magnetic displacement sensor, SPI, 3.3V or 5V. Magnetic linear click is a very accurate position sensing Click board™ which utilizes the HMC1501, a magnetic field displacement sensor IC. This integrated sensor uses a single saturated-mode Wheatstone bridge which consists of four magneto-resistive elements. The precision of up to 0.07° in the angular range of ±45° can be easily achieved using the Magnetic linear click, making it far more accurate than the commonly used Hall-effect sensors. The HMC1501 sensor IC produces a highly linear voltage output signal in respect to the magnetic field angle, available directly from the bridge via two differential output pins. To allow simplified usage, the Magnetic linear click features an additional A/D converter, making it a complete solution for the rapid development of various contactless position and direction sensing applications, HMI interfaces, precision measurement applications, proximity detection applications, etc. Applications: Magnetic linear click can be used for development of various contactless position and direction sensing applications, HMI interfaces, precision measurement applications, proximity detection applications, etc. On-board modules: HMC1501, a magnetic displacement sensor, from Honeywell. MCP6022, a dual, rail-to-rail operational amplifier. MCP3201, a 12-bit A/D converter with SPI interface by Microchip. Key Features: A very high precision is achieved by implementing the proprietary Anisotropic Magneto-Resistive (AMR) technology from Honeywell, absolute sensing of the magnetic field, very compact size, differential outputs from the internal Wheatstone bridge. Interface: SPI. Input Voltage: 3.3V or 5V. Click board size: S (28.6 x 25.4 mm).
