Hall Sensor in Mobile Phones

Hall Impact Sensors are used in various electronic products as they are extremely tiny, as well as insusceptible to vast temperature modifications, which is specifically beneficial for phones and typically equipped with magnets.

When a flip cover is closed, the magnet is brought towards the Hall sensing unit on your smartphone or tablet computer. Flip covers supply the electromagnetic field, which produces Hall voltage. Through utilizing a Hall impact sensing unit, battery life is extended by disabling the display when it is covered, as well as not be utilized. (AH3661)

Hall Sensor in TWS Bluetooth Headset

Bluetooth headset is the Bluetooth technology (Definition: a short-range wireless communication technology) applied to the hands-free headset, so users can avoid the troubles of the original line headphones, more convenient to easily call or entertainment in various ways. Since the advent of Bluetooth headset, it has been a good candidate for business people, office workers to enhance work efficiency, it is welcomed by all ages.

The TWS (True Wireless Stereo, True Wireless Bluetooth Headset) needs to detect the opening and closing of the charging compartment cover and whether the headset is in place, and in this detection function, Hall devices are becoming more and more popular because of their responsiveness, small size and low power consumption.
