ItemName : 10PC HC-SR04 shiping to World Ultrasonic Wave Detector Ranging Module HC-SR04 HC SR04 HCSR04 Distance Sensor
ItemTypeKeyword : ultrasonic-proximity-sensors
Manufacturer : tfdz
PartNumber : 12371
ProductDescription : This module has stable performance and accurate measurement distance. Module
high-precision, blind (2cm) ultra-close, stable range is the success of this
product to the market a strong basis! This module fully humility GH-311 anti-
theft module.
(1) using IO trigger ranging,to at least 10us of high-level signal;
(2) the module automatically sends eight 40khz square wave, automatically
detect whether there is signal return;
(3) there is a signal return, through the IO output of a high, high duration
is the time from the launch to the return of ultrasound.
Test distance = (high time * sound speed (340M / S)) / 2;
This product is simple to use, a control mouth made a 10US above the high
level, you can wait for the reception of high-level output. An output can be
opened timer, when the mouth becomes low when you can read The value of the
timer, this time for the distance of time, can be calculated from the
distance. Such a continuous cycle of measurement, you can move the measured
value
The module features:
1: Working voltage: DC5V
2: Quiescent current: less than 2mA
3: Level output: High 5V
4: Level output: Bottom 0V
5: Sensing angle: not more than 15 degrees
6: Detection range: 2cm-450cm
7: High precision: up to 0.3cm
