Power supply: 3.3V to 5V DC D8 sensor array: eight sensors arranged from left to right Output: D8 provides an analogue signal; the output is typically high when the device is powered on Sensing behavior: obstacles can be used to test the sensor; the output varies with the distance of the obstacle Compatibility and performance: designed for compatibility with 3.3V-5V systems; simple analogue output suitable for straightforward interfacing Use scenarios - Robotics and automation projects that require eight analogue readings to detect obstacle distance or blockage - Prototyping sensors in compact platforms where space and power constraints matter - Educational labs to demonstrate analogue sensing and distance-based output with a multi-sensor array Notes - Ensure compatible 3.3V-5V power supply and appropriate analogue input for reading D8 output - Real-world readings depend on obstacle distance and ambient conditions
