KY-025 Dry Reed Pipe Module

1. Adopt imported normally open spring pipe 2. Comparator output, clean signal, good waveform, strong driving ability, more than 15mA. 3. Output form: Digital switching output (0 and 1) 4. Operating voltage:3.3V-5V 5. Fixed bolt hole for easy installation 6. PCB size of small board: 35mm*15mm 7. Use wide voltage LM393 comparator This module can be applied to program-controlled switches, copiers, washing machines, refrigerators, cameras, disinfection cabinets, door magnets, window magnets, electromagnetic relays, electronic scales, liquid level gauges, gas meters, water meters, etc. Directions for use ●The reed pipe needs to be used in conjunction with the magnet. When certain magnetic force is induced, itwill be in the on-off state and the module will output low level; when no magnetic force is present, it will be disconnected and output high level. The induction distance between the reed pipe and the magnet is within 1.5cm, which is insensitive or will not trigger. ●The output end of the module D0 can be directly connected to the V0 port of the single-chip microcomputer, through which the trigger state of the spring pipe can be detected. ●The output end of module DO is connected with the relay iN end to form a high-power dry spring pipe switch to directly control high voltage.
