80 cm infrared proximity sensor
The 80 cm infrared proximity sensor is a general purpose distance measuring sensor based on the Sharp GP2Y0A21YK, a wide-angle distance measuring sensor. This proximity sensor continuously measures distance and returns a corresponding analog voltage with a range of 10 cm (4 inches) to 80 cm (30 inches).
The sensor is quite small and uses a JST connector (ground, VCC and output). Since the sensor triggers continuously and does not require a clock pulse to trigger a measured value, it can be easily connected to any microcontroller. On the Seeeduino 4.2, the wire converts the 3-wire to a 4-wire, making it compatible with Grove's Twig interface.
Features:
- Large detection range: Non-contact distance detection range between 10 cm and 80 cm and angular range from 4 to 30 inches
- High response speed: The response time of the sensor is only 39 ms
- Simple digital output: The output of digital signals is easier to handle
- Grove unit socket: The product ensures "plug and play" and can be versatile for various applications
- Compact size, easy to install: The small size makes it easy to carry and install at the detection site
Application:
- Toys
- Robotics

What is Grove?
Grove facilitates connection, experimentation and simplifies the prototyping process. No jumpers or soldering required. More than 300 Grove modules have been developed to cover a wide range of applications and fulfill a variety of requirements. Not only the hardware is open source, but also the software. Instructional PDF documents and a wiki are provided for Grove users (especially beginners).
We offer various Grove Shields to enable connection to the Grove system with various microcontrollers.
