Ask a question about this product


The Sonar Range Finder is ultrasonic based distance measurement sensor. With a 5Volt power, sensor provides very short to long range detection. It can detect object from 2 inches to 120 inches(3 Meters). The interface output formats included are pulse width output, analog output and serial digital TTL output and all these output interfaces are active simultaneously. It's triggered and free running operating mode makes this sensor module perfectly suitable for robotic applications. This sensor module package comes with 7 pin 2510 relimate connector. This sensor is an excellent choice when only larger and plane surface objects need to be detected. Pins description and its working is described in application note of Sonar Range Finder.

Note: 1.Closest range detection by this sensor module will be 2 inches. The module is more likely to have false close reading if user tries to measure distance below 2 inches.
2.Output available on sensor's all output interfaces will be maximum if object to be detected is not in sensor's range.
