Hall switches in sweeping robots are often used for obstacle detection. The Hall switch sensor installed at the bottom of the robot can sense magnetic objects or magnetic boundaries on the ground. When the robot approaches an obstacle, the Hall switch triggers the switch action, causing the robot to change direction or stop moving forward to avoid collision or getting into trouble.
Hall switches play a key safety role in the motor control of sweeping machines. When the motor is abnormal or overloaded, the Hall switch can detect it in time and quickly cut off the power supply to prevent the robot from being damaged by motor problems. This provides an effective layer of safety protection for sweeping robots.
By realizing the control, safety monitoring and position detection of the motor, the sweeping robot can complete the cleaning task more efficiently and intelligently, providing users with a convenient and efficient home cleaning experience. Recommended model: HS41F bipolar latch Hall element
HS41F high temperature bipolar latch Hall effect position sensor is a magnetic sensing circuit composed of an internal voltage regulator unit, a Hall voltage generator, a differential amplifier, a temperature compensation unit, a Schmitt trigger and an open collector output stage. Its input is magnetic induction intensity and its output is a digital voltage signal.
It is a dual-pole magnetic sensing circuit suitable for working under rectangular or cylindrical magnets.
The operating temperature range can be from -40℃ to 150℃, the power supply voltage range is from 3.8V to 30V, and the load current capacity can reach up to 40mA.
The package form is SIP3L (TO92S).
