Support sensitivity adjustment and delay switch adjustment;<br /><br />2. Stable performance, supporting human infrared sensing;<br /><br />3. Supports dual mode switching and selection through jumper caps;<br /><br />4. Relay delay switch knob, which can adjust the length of delay;<br /><br />5. With cascading ports, it can be used for program burning and self-developed programs.<br /><br /><strong><span style="font-size: 20px;">Product Introduction:</span></strong><br /><br />The human infrared sensing single relay module is programmed by the STC8G1K08A chip. When the module senses someone nearby, it turns on the relay and supports functions such as dual mode switching, sensitivity adjustment, and switch delay adjustment. Users can also develop their own programs through the introduced burning pins.<br /><br /><strong><span style="font-size: 20px;">Product parameters:</span></strong><br /><br />Power supply port: 5V<br /><br />Human body sensing sensor: BM412<br /><br />Cascade port: capable of program burning<br /><br />MCU: STC8G1K08A<br /><br />Relay: 5V relay<br /><br />Mode selection: Remove the jumper cap to select Mode 1; Insert the jumper cap as mode two<br /><br />Human sensitivity knob: counterclockwise increases sensitivity, clockwise decreases sensitivity<br /><br />Relay delay switch knob: counterclockwise reduces delay time, clockwise increases delay time<br /><br /><strong><span style="font-size: 20px;">Module Instructions</span></strong><br /><br />1. Provide power to the human infrared sensing single relay module (5V power supply);<br /><br />2. There are two modes in the module, which are:<br /><br />Mode 1: Do not repeat mode, unplug the jumper cap to set it to Mode 1. In this mode, when someone is active nearby, the relay will automatically turn off after opening for a period of time<br /><br />Mode 2: Repeat mode, plug in the jumper cap to set it to Mode 2. In this mode, when someone is active nearby, the relay will remain open until the module does not detect any activity nearby, and the relay will turn off;<br /><br />3. By turning the human sensitivity knob, the sensitivity of the module can be adjusted. Turning counterclockwise enhances sensitivity, while turning clockwise weakens sensitivity; By turning the relay delay switch knob, the duration of relay activation in Mode 1 can be adjusted. Turning counterclockwise reduces activation time, while turning clockwise increases activation time.<br /><br /><strong><span style="font-size: 20px;">Product List:</span></strong><br /><br />1X module<br /><br />1X 4pin single row pin<br /><br /><br /><br /></p></div></div>
