As people's living standards improve, they pay more and more attention to their quality of life. Modern people live a fast pace and often ignore some details in daily life. As we all know, bacteria are everywhere. For example, the current more difficult new coronavirus is indeed a very annoying thing. It is still necessary for us to avoid contact with it in daily life, and even find ways to eliminate it. So the portable disinfection box was brought into people's lives. It can generate ultraviolet rays to sterilize and disinfect small objects.

The induction control function of the Hall switch in the disinfection box. The disinfection box can sense the placement status of the items. When the items are placed in the disinfection box, the Hall switch will sense the changes in the magnetic field and trigger the corresponding disinfection program. This intelligent induction enables the disinfection box to automatically start the disinfection process as needed, improving the level of health protection.

Because it is easy to carry, all portable disinfection boxes require small size and battery power supply, so the Hall switch requires low power consumption, high sensitivity, good consistency, and convenient magnet installation. The Hall switch detects non-polar magnets and can be triggered only by magnets. Recommended model: HS627 non-polar low-power Hall chip

HS627 is a micro-power, high-sensitivity omnipolar Hall switch sensor with latch output, which can directly replace the traditional reed switch. It is particularly suitable for portable electronic products that use battery power, such as mobile phones, cordless phones, notebook computers, PDAs, etc.
HS627 has magnetic field recognition omnipolarity, that is, it can be activated as long as the north pole or south pole of the magnetic field is close, and the output will be turned off after the magnetic field is removed. Unlike other general Hall sensor devices, it does not require a specific south pole or north pole to operate, which reduces the trouble of identifying magnetic poles during assembly. The internal circuit includes a Hall chip, a voltage regulator module, a signal amplification processing module, a dynamic offset elimination module, a latch module, and a CMOS output stage. Due to the use of advanced Bi-CMOS technology and the overall optimized circuit structure, the product obtains extremely low input error feedback. The product uses dynamic offset elimination technology, which can eliminate the offset voltage caused by package stress, thermal stress, and temperature gradient, and improve the consistency of the device. At the same time, the product adopts a very miniaturized packaging process, which makes the product have extremely high performance and market advantages.

HS627 provides two packages: TSOT23-3 and TO-92S, and the operating temperature range is -40~150℃.
