Description
HC-SR04 ultrasonic distance sensor with mounting bracket, 2 pack. Each set includes one HC-SR04 module, one transparent mounting bracket, mounting screws, and jumper wires.
Detection range is 2-450cm with 0.3cm resolution and an effective angle under 15 degrees. Quiescent current is under 2mA. Power is 5V DC. Trigger with a 10 microsecond high level pulse on the Trig pin, and the module sends eight 40 kHz pulses and reports the echo time on the Echo pin.
Good for robot navigation, obstacle avoidance, parking distance prototypes, automatic lids, and distance measurement projects. For a 5 pack without brackets, see the 5-pack listing.
