HC-SR04 Ultrasonic Sensor + Bracket TYPE:US-015 FL) to SMA Male toThe classic HC SR04 ultrasonic distance sensor. Fires 40kHz pulses and times the echo to measure distance with no contact. The workhorse for obstacle avoidance robots, parking sensors, and level detection. Four pins and a simple pulse timing sketch is all you need, no library required. Bracket variants make it easy to mount in a chassis or enclosure. COMBI options pair the sensor with a bracket in one pack. Specs Range 2cm to 400cm Frequency 40kHz
