RCWL-9620 ultrasonic distance sensor - extension module for M5Stack development modules

Unit series expansion module - ultrasonic distance sensor manufactured by M5Stack. The extension is compatible with M5Stack Core, M5Atom and M5Stick development modules. The sensor is equipped with the RCWL-9620 chip, which can accurately measure the distance and detect an obstacle from 20 mm to 4500 mm, and the measurement is determined with an accuracy of about 2%. Communication with the development module is via the I2C interface. Grove type cables are used to connect the extension with the main modules. A dedicated 20 cm long connection cable is included.

• The module allows for precise distance measurement in the range of 2 cm to 450 cm with an accuracy of about 2%
• Wide viewing angle of 60 degrees allows detection of objects that are not directly in front of the sensor
• Uses I2C bus to communicate with development modules
• Can be used in obstacle avoidance robots, distance measuring projects and object detection
• It is equipped with RCWL-9620 chip

The sensor also comes with a 20 cm long connecting cable.
