Description: 1. SN04-N is an NPN (Normally Open) NO (Normally Closed) proximity sensor switch module, suitable for various IoT applications where contactless object detection is required. 2. Technology: It utilizes advanced ultrasonic sensing technology to detect objects within its range without physical touch, making it ideal for sensors that require non-contact interaction. 3. Operation: The SN04-N module switches between ON and OFF states based on the presence or absence of an object within a specific proximity range (approximately 5-15mm). 4. Input Voltage: This sensor operates efficiently with a working voltage ranging from 3.3V to 5V DC, providing flexibility for various IoT projects and devices. 5. Output Characteristics: The NPN output configuration of this module allows for active low logic, which can be easily integrated into most microcontroller-based systems or digital circuits. 6. Detection Range: Its adjustable detection range enables users to fine-tune the sensor's sensitivity
