Mouser Electronics is stocking the SparkFun Qwiic Ultrasonic Distance Sensor - HC-SR04. It provides non-contact distance readings ranging from 2cm to 400cm. This ultrasonic distance sensor features an STM8L051 microcontroller and offers an accuracy of 3mm. The Qwiic ultrasonic distance sensor can be improved by adding a pair of Qwiic connectors to it that help users to communicate over I2C and daisy chain. The users can bypass the Qwiic connector and I2C to access the VCC, trigger, echo, and ground pins. This sensor offers to detect an angle up to a range of 15 degrees and operates at 3.3V supply voltage.
