- The -D8 output mode provides an analogue signal that is typically high when the device is powered on. - Blocking the sensor with an obstacle changes the analogue reading, and the reading varies with the distance to the obstacle. - Power supply: 3.3V to 5V DC. - -D8 maps to eight sensors arranged from left to right. This supports eight channel sensing in a single module. Key benefits and how it helps - Multi channel proximity sensing: Eight sensors in a single row allow broad coverage and continuous analogue feedback rather than a simple on/off signal. - Easy integration with low voltage systems: Designed for 3.3V to 5V operation, enabling straightforward use with a wide range of microcontrollers and development boards. - Simple interpretation of distance information: The analogue output provides distance-related readings as objects block each sensor, supporting applications that require proximity awareness. - Straightforward mapping: The eight sensors are ordered from left to right, simplifying software indexing and board wiring in projects. 2-3 practical use scenarios - Small robot obstacle avoidance: Use the eight sensor outputs to detect obstacles at multiple positions along the front of a robot and generate a proximity-based avoidance strategy. - Line following or mapping projects: Deploy the array to sense obstacles or walls in a workspace, creating a simple map of nearby objects for navigation or exploration tasks. - Educational experiments and prototyping: Use the eight analogue channels to teach analogue sensing, distance estimation, and multi-sensor data fusion in a lab or DIY environment. Notes - The module relies on obstacle blocking to produce readings, with the analogue value influenced by obstacle distance. - Compatible with systems that supply 3.3V to 5V power.
