Adafruit HC-SR04 Ultrasonic Sonar Distance Sensor + 2 x 10K resistors

Transform your projects with the HC-SR04 Ultrasonic Sonar Distance Sensors, ideal for robotics, automation, and interactive installations. These sensors detect objects accurately from 2cm to 400cm, with optimal performance between 10cm and 250cm.Designed for efficiency and ease of use, the sensors require a 5V power supply. Connect GND and VCC to 5V power for best results. While the Trig signal is compatible with 3V or 5V, the Echo signal outputs at 5V logic. Included are two 10K resistors to create a safe voltage divider for reading with 3V devices.Looking for enhanced features? The US-100 model supports 3.3V logic and includes temperature reading with UART output. Compatible with platforms like Arduino, CircuitPython, and MakeCode, these sensors integrate seamlessly into various ecosystems.
