#22 Comparison of precision between Neo-M8N and Neo-6M Modules
About Ultrasonic Range Sensor module:
This performance of the ultrasonic sensor distance measuring module is stable, measure the distance accurately. The module is with High precision, blind spots (3cm) super close. This module provides a full set of ranging process.
Operating voltage: 5V DC; Static current: Less than 2mA; IO logic voltage: 5V;
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;
Adopt IO trigger through supplying at least 10us sequence of high level signal;
The module automatically send eight 40khz square wave and automatically detect whether receive the returning pulse signal;
If there is signals returning, through outputting high level and the time of high level continuing is the time of that from the ultrasonic transmitting to receiving.
About 4-Digit Display module:
The module is based on a decimal point display module, it displays four digital tube (0.56 inches), only two signal lines can make MCU control four Digit 8-segment LED. Can be used to display decimal, letters and so on;
Can display the measuring distance by the ultrasonic range module;
8 class adjustable brightness
Color:Blue + Black.
Material:PCB + plastic.
Application:Measure the distance and display.
English Manual / Spec :Yes.
1 x Ultrasonic range sensor module.
