SKU: SEN0304
This is the Gravity URM09 ultrasonic distance sensor module with open dual probes. It uses I2C communication and a Gravity PH2.0-4P vertical socket interface. Compatible with 3.3V/5V controllers (Arduino, Raspberry Pi), it has built-in temperature compensation. Effective ranging: 2cm-500cm, 1cm resolution, ±1% accuracy. Selectable ranges (150/300/500cm): shorter ranges mean shorter cycles but lower sensitivity.

FAQ
Many ultrasonic sensors on the platform, how to choose?
It is recommended to refer to this selection guide.
The detection range of an ultrasonic sensor depends on the wavelength and frequency it uses. The longer the wavelength and the smaller the frequency, the greater the detection distance. The following is the detection range of several popular products on our platform for your reference.
