The MRMS201A-001 is a 3.0V Board Mount Hall Effect/Magnetic Sensor manufactured by Murata. This sensor is designed to detect magnetic fields and detect magnetic poles. It has an operating current of 5µA and a maximum operating temperature of 3.0°C. It is a range of detectors that feature low power consumption, high magnetic sensitivity, and wide resistance to magnetic disruption. It has an output compatible with CMOS/TTL logic operation, meaning that it can directly interface with devices that use these digital logic, such as microcontrollers. This sensor can also be used for monitoring current flows and position detection.
