Product description

Description:

- Adopts IO port trigger for at least 10us high level signal.
- It can send eight 40khz square wave automatically, and detect if there is any signal returned.
- If the signal returning, output one high level signal via IO port. The duration of the high level signal is the time from sending to returning.
- Measuring distance=duration of high level x sound velocity(340m/s)/2
- Power supply :5V DC; Quiescent current :lt;2mA; Ranging distance : 2cm~450cm; High precision: Up to 0.3cm

Specification:

- Mode: HC-SR04 module
- Working voltage : DC 5V
- Static current: Less than 2mA
- Output signal: Electric frequency signal, high level 5V, low level 0V
- Sensor angle: No more than 15 degrees
- Detection distance: 2cm~450cm
- High precision: Up to 0.3cm
- Input trigger signal: 10us TTL
- signal : output TTL PWL signal
- Mode of connection: VCC; trig(T); (R); GND
Using Method:
- A control port sends a high level above 10US to wait for a high output at the receiving port.
- The output can be started by the timer. When this port become low level, it can read the value of the timer. At this time, it is the time of this distance measurement.So it can calculate the distance, you can reach the value of your mobile measurement according to such continuous cycle test

Package Includes:

1 Piece Distance Measuring Module
