Ultrasonic Wave Detector Ranging Module PICAXE Microcontroller Sensor HC SR0 for Arduino/51/STM32
$0.89
Brand：Spotpear
SKU：0205025
Date：2021-06-03 15:02
Part Number：
Ultrasonic Wave Detector Ranging Module PICAXE Microcontroller Sensor HC-SR0 for Arduino/51/STM32
the module URF04 works:
- (1) IO trigger ranging to at least 10us high signal;
- (2) module automatically sends eight 40kHz square wave, automatically detect whether a signal return;
- (3) a signal to return to a high IO output, high duration of the ultrasonic time from launch to return.
- Test distance = (time high * speed of sound (340M / S)) / 2;
main technical parameters:
- 1: Voltage: DC5V
- 2: Quiescent Current: <2mA
- 3: level output: the output of the high-5V
- 4: level: the end of 0V
- 5: Induction Angle: not more than 15 degrees: detection range: 2cm-450cm
