Electronic DIY Ultrasonic Sensor HC-SR04 Ultrasonic Module For Arduino
Description:
1.Working Voltage : 5V(DC)
2.Static current: Less than 2mA.
3.Output signal: Electric frequency signal, high level 5V, low
level 0V.
4.Sensor angle: Not more than 15 degrees.
5.Detection distance: 2cm-450cm.
6.High precision: Up to 0.3cm
7.Input trigger signal: 10us TTL impulse
8.Echo signal : output TTL PWL signal
Specifications:
Mode of connection:
1.VCC
2.trig(T)
3.echo(R)
4.GND
Module working principle:
(1) using IO trigger location, to at least10us high level signal;
(2) module to automatically send8 40KHz square wave, to automatically detect whether a signal return;
(3) a return signal, through the IO outputs a high level, high level for a time is
Ultrasonic wave from the transmitter to the return time. Testing distance = ( high level time * speed of sound (340M/S ) ) /2;
Competitive Advantage:
1. Convenient & Friendly Customer Service
2. Low Prices Direct From Factory Suppliers
3. Fast Delivery Around the World.
4. High Quality With Global Standards.
5. 1 Year Factory Warranty
6. Safe Shipping Way and Payment
