PH2.0 Flame Sensor Arduino Module
This infrared obstacle avoidance sensor module offers strong adaptability to ambient light and features a pair of infrared transmitter and receiver LEDs for reliable object detection. The infrared transmitter emits infrared light at a specific frequency. When an obstacle or reflective surface is detected within the sensing direction, the infrared light is reflected back to the receiver and processed by the onboard comparator circuit.
When an object is detected, the blue indicator LED lights up, while the signal output interface provides a digital low-level signal. The detection distance can be easily adjusted using the onboard potentiometer, with an effective sensing range of approximately 2–30 cm.
The module operates from a 3.3V–5V power supply, making it compatible with a wide range of microcontrollers and development platforms. With low interference, adjustable detection distance, easy installation, and convenient operation, this sensor module is well suited for various automation and robotics applications.
