Hall switches are often used to detect the rotation and counting of rope skipping in intelligent counting rope skipping. By installing Hall switches and magnets on the handle or rope of the rope skipping, the rope skipping action can be monitored and counted.
When the rope skipping rotates, the magnet approaches the Hall switch, and the magnetic field generated will make the Hall switch in the on state. After receiving the on signal, the signal processing circuit recognizes that the rope skipping is rotating. The number and time of rope skipping can be calculated by the rotation speed and frequency of the rope skipping.
Recommended model: HS475 non-polar Hall magnetic control switch for rope skipping
HS475 is an omnipolar Hall effect sensor based on mixed-signal CMOS technology. This IC uses advanced chopper stabilization technology, so it can provide accurate and stable magnetic switch points.
In terms of circuit design, HS475 provides an embedded controlled clock mechanism to provide a clock source for the Hall device and analog signal processing circuit. At the same time, this controlled clock mechanism can send a control signal to make the circuit with high current consumption enter the "sleep" mode periodically; through this mechanism, the chip is periodically "woken up" and detects the strength of the magnetic field passing through the Hall device according to the predetermined magnetic field strength threshold. If the magnetic flux density is higher than the "operating point" threshold or lower than the "release point" threshold, the open-drain output transistor is driven and latched into the corresponding state. In the "sleep" cycle, the output transistor is locked in the previous state. In battery-powered applications, this design provides the best support for extending the working life.
The output transistor of HS475 will be locked in the open (BOP) state when there is a certain strong south pole or north pole magnetic field on the side facing the package marking, and locked in the off (BRP) state when there is no magnetic field.
