SRF02 Ultrasonic Distance Sensor (16~600cm)

This low-cost SFR02 ultrasonic ranger stands out with its dual I2C and Serial interfaces, making it a versatile choice for various projects. The device boasts an advanced AutoTune algorithm, which enhances performance by pushing the minimum range close to the transducer ringdown, all without requiring any calibration cycles. This seamless feature operates automatically, ensuring optimal efficiency in the background.

Equipped with a standard TTL level UART format at 9600 baud, the SRF02 can be linked directly to the serial ports of any microcontroller. Its ability to connect up to sixteen units on either an I2C or Serial bus highlights its scalability and flexibility for complex configurations. Whether used individually or in arrays, the SRF02 integrates smoothly into diverse environments.

Innovative commands enrich the SRF02’s functionality, allowing users to initiate an ultrasonic burst separately from the reception cycle or execute a reception without a prior burst. This unique capability stems from its single transducer design, a feature that differentiates it from dual transducer variants. Although this design raises the minimum measurement range to approximately 15 cm, the SRF02 continues to offer precise readings in microseconds, centimeters, and inches, preserving the reliability expected from Devantech rangefinders.
