The sensor part is essentially a reed switch encased in a plastic shell. Normally the reed switch is in open state but when the magnet part comes close to the sensor part, the reed switch closes ...

This compact and affordable door sensor mechanism uses a Hall-effect sensor fixed at the corner of the door frame and a standard bar magnet fixed on the door panel close to the Hall-effect sensor.

Magnetoresistance ratio enhancement opens door to highly sensitive magnetic field sensors Date: December 20, 2018 Source: American Institute of Physics Summary: By creating a new multilayer ...

For one, the Nest Guard acts as the central hub, so all the disarming and arming of the security system is done through that device, which contains a motion sensor, connects to your home network ...

Two new TMR-based magnetic angle sensors boost measurement precision in harsh environments with minimal thermal drift.

Programmable for PIR sensor (movement), phototransistor (light), or door sensor input (magnetic contact switch) to detect occupancy. Programmable to flash and beep if Help Button is pressed.

Littelfuse announces the launch of two new TMR-based magnetic angle sensors – the LF53466 and LF53464 – designed to deliver ...

Quantum tech is going green. A new take on highly sensitive magnetic field sensors ditches the power-hungry lasers that previous devices have relied on to make their measurements and replaces them ...
