HOA1180-002 Application Field and Working Principle

The HOA1180-002 is an optical reflective sensor that uses analog output to detect obstacles and solid objects within a local area. It is classified as an Optical Sensors - Reflective - Analog Output type of sensor and is used in a number of applications, from collecting environmental data, to aiding autonomous robots in navigation and object detection.

Operation Principle

The operation of the HOA1180-002 is based on the same principle of how cameras detect objects in a scene: it uses reflection to register the presence of objects. This reflective type of sensor is able to detect the distance and relative positions of obstacles and solid objects by emitting a beam from its built-in emitter and triangulating the reflected light on its photodetector.

Analog Output

The HOA1180-002 is equipped with an integrated circuit that converts the change in the photodetector value into a linear analog output from 0.0V through 0.5V. Where the analog voltage output is 0.0V, it indicates no obstacles are detected while a voltage output beyond 0.5V indicates there is an obstacle detected at the particular spot. This makes the HOA1180-002 extremely well suited for indoor and short-distance sensing applications as it is able to provide precise analog readings that can be quickly visible by human eyes or easily integrated into a microcontroller-based system.

Applications

The HOA1180-002 has been extensively used in a variety of applications, including automotive, robotics, and industrial automation. In applications such as automotive, it has been seen to be used as a blind spot detection system to detect the presence of cars or pedestrians in the way of an automobile through the use of its analog output. This helps ensure the safety of drivers as it enables them to see objects within their blind spot

In robotics, the HOA1180-002 has seen extensive use as an obstacle detection and proximity sensor. For example, it is able to accurately detect and measure the distance between itself and a wall with high accuracy, allowing the robot to make navigation decisions with higher accuracy and precision. It has also found use in indoor positioning systems, used in tasks such as cleaning and object sorting.

In industrial automation, the HOA1180-002 has been used as an automatic sorting system to sort objects, for example sorting coloured objects. In this application, a beam is focused onto the object and the reflected beam is triangulated by the photo detector to measure the distance between the emitter and object. The information is then processed to understand the colour of the object and is then sent to the sorting system.

Conclusion

The HOA1180-002 is an optical reflective sensor that uses analog output to detect obstacles and solid objects within a local area. It falls into the category of Optical Sensors - Reflective - Analog Output type of sensor and has been found useful in a wide range of applications, ranging from automotive to robotics and industrial automation.
