US-020 Ultrasonic Sensor Module For Raspberry Pi Arduino Robot NEW
US-020 Ultrasonic Sensor Module 4m Distance For Raspberry Pi Arduino Robot NEW
The US-020 ultrasonic sensor uses sonar to determine distance to an object like bats or dolphins do. It offers excellent range accuracy and stable readings in an easy-to-use package. It operation is not affected by sunlight or black material like infrared rangefinders are (although acoustically soft materials like cloth can be difficult to detect).
Ultrasonic Ranging Module US-020 provides 2cm-700cm non-contact distance sensing capabilities. Ranging accuracy up to 3mm; module comprises an ultrasonic transmitter, a receiver and a control circuit.
Basic operating principle:
IO port TRIG trigger ranging to at least 10us high level signal;
the module automatically sends eight 40khz square wave, automatically detects whether a signal return;
a signal to return to a high output through the IO port ECHO high duration of ultrasound wave from the transmitter to the time of the return. Test distance = (high level time * sound velocity (340M / S)) / 2;
Reliable, high performance, high accuracy, blind area within 3cm.
