GP2Y0D805Z0F is an infrared distance measuring sensor module developed by Sharp company. It is a optical distance measuring device based on infrared beam technology. In this article, the application field and working principle of GP2Y0D805Z0F will be discussed.

GP2Y0D805Z0F has a wide range of application areas. It can be used in robotics, surveillance, or security systems, as well as home automation, car security, distance measuring, and environmental data sensing. The sensor uses infrared beams to calculate distances between 0.3 and 8 meters. The module is designed to measure distances accurately in various environments and at different angles.

GP2Y0D805Z0F has two operating modes. In analog mode, the analog voltage output is directly proportional to the measured distance, while in digital mode, a low-level external pulse is used to request measurement and the 1-Wire digital stream is used to receive the measured distance value. The operating frequency of the digital mode is 25Hz.

The working principle of GP2Y0D805Z0F is based on infrared beam technology. The sensor consists of two parts: the transmitter and the receiver. The transmitter emits a modulated infra-red beam in a narrow beam angle. When the beam is blocked by any obstacle, a part of the beam is reflected back to the receiver. The time difference between the emitted pulse and the peak of the reflected pulse is measured by the receiver. This time difference is used to calculate the distance of the obstacle from the transmitter. The higher the distance, the longer the reflected pulse peak delay.

In addition, GP2Y0D805Z0F also has the saturation output protection and noise prevention that can effectively prevent false readings. The saturation output protection will ensure that the sensor output will not be affected by reflected direct sunlight (for outdoor applications). A four-channel A/D converter is used to filter outside noise and interference.

To sum up, GP2Y0D805Z0F is an infrared distance measuring sensor module developed by Sharp company. It offers two operating modes: analog and digital, with a wide range of application areas. The working principle of GP2Y0D805Z0F is based on infrared beam technology and it also has built in anti-noise protection and saturation output protection to ensure its accuracy.
