The TMR1302 water flow detection Hall magnetic switch is a magnetic sensor developed for high sensitivity, high speed, low power consumption, and high precision applications, integrating TMR and CMOS technologies. The Hall element TMR1302 utilizes a high-precision push-pull half-bridge TMR1302 magnetic sensor and CMOS integrated circuit, including a TMR voltage generator, comparator, Schmitt trigger, and CMOS output circuit, capable of converting changing magnetic field signals into digital voltage signal outputs. An internal voltage regulator provides a temperature-compensated power supply and allows for a wide operating voltage range. The MAR211 operates at low voltage, consumes low current, and has a high response frequency, making its microampere-level current consumption an ideal choice for numerous low-power applications.
