4MM thick enough to stand using the new material high strength acrylic panels, the first exclusive design simple and robust structure that can withstand greater impact force.
Product application areas:
Robot obstacle avoidance / object distance / level detection / public security / parking detection
The main technical parameters:
1: Voltage: DC5V
2: Static current: less than 2mA
3: Level Output: 5V High
4: level output: 0V Low
5: Sensor angle: not more than 15 degrees
6: Detection distance: 2cm-450cm
7: Accuracy: 3mm
Wiring, VCC, trig (control side), echo (receiving end), GND
The basic operating principle:
(1) using the IO port TRIG trigger distance, at least 10us high level signal;
(2) the module automatically sends eight 40khz square wave and automatically detects whether a signal return;
(3) a signal is returned, through the IO port ECHO outputs a high level, high duration is Ultrasonic time from launch to return. Test distance = (time * High speed of sound (340M / S)) / 2;
