Reed Sensor Magnetic Switch Module DIY Kit (4 pcs/set) - Normally Open

Welcome to our shop! We are pleased to introduce our imported normally open reed module. This module features a clean output signal with a good waveform and a driving ability of more than 15mA. The output form is a digital switching output (0 and 1). It also has a fixed bolt hole for easy installation. The module uses a wide voltage comparator LM393 and has a small PCB board size of 3.2cm x 1.4cm. It is suitable for various applications such as SPC exchange, copy machines, washing machines, refrigerators, cameras, disinfect cupboards, door magnets, window magnets, electromagnetic relays, electronic weighing apparatus, level meters, gas meters, and water meters. Specifications: - Working voltage: 3.3V-5V - Type: Normally-open - Comparator: LM393 - Output type: Digital output (0 and 1) - PCB board size: 3.2cm x 1.4cm - Weight: Approx. 13g/0.5oz The module is easy to use. The dry reed pipe needs a magnet to sense a certain magnetic force. When it senses the magnetic force, it shows an ON state and the module outputs a low level. When there is no magnetic force, it shows an OFF state and the module outputs a high level. The module can be connected directly to a microcontroller I/O port to detect the status of the dry reed pipe. It can also be connected to the IN end of a relay to control high voltage directly.
