The performance of the ultrasonic sensor distance measuring module is stable and measure the distance accurately. The module is with High precision, blind spots (3cm) super close. This module provides a full set of ranging process.
The mounting bracket is only compatible with the HC-SR04 ultrasonic ranging module, and not with other sensor modules
Features of Ultrasonic sensor:
- Working voltage : 5V(DC)
- Static current: Less than 2mA.
- Output signal: Electric frequency signal, high level 5V, low level 0V.
- Sensor angle: Not more than 15 degrees.
- Detection distance: 2cm~450cm.
- High precision: Up to 3mm
- Mode of connection: VCC / trig(T) / echo(R) / GND
Features of Sensor Mounting Bracket:
- Thickness: 2.8-3.1mm
- Inner diameter: 16mm
- Fixed hole diameter: 3.8MM
- Material: Imported acrylic
- use: fixed ultrasonic sensor module and other products
- Provide the IO trigger supplying at least 10us sequence of high level signal
- The module automatically sends eight 40khz square wave and automatically detects whether receive the returning pulse signal
- If there is a return signal, the output level will be high and the high time of the signal is the time from transmitting to receiving. Please refer the datasheet for exact details.
