Description
Sonar:bit is an ultrasonic module with a 3-5V working voltage. It is available to be used in a 3.3V or 5V microcontroller system. With only one 3-wire(GVS) cable, it can work properly. Compared to the normal 4-wire ultrasonic module, it has saved one IO port. The measurement range of sonar:bit is 4cm-400cm. It can output stable and accurate measurement data with ±1cm tolerance only. You can use this module for occasions like short-distance measurement, smart cars, robots, micro:bit and Arduino teaching, etc.
Features
Input voltage: 3V~5V
Enable to drive micro:bit or Arduino directly.
Standard 3-wire GVS connector, which occupies 1 IO port only.
Dimension
Definition
Transmitter
The transmitter is used to send ultrasonic signals.
Receiver
The receiver is for collecting ultrasonic signals.
MCU
This is the master chip of sonar:bit.
Chip for Sending Signal
This chip is used to drive the transmitter to send out ultrasonic signals.
Chip for Receiving Signal
This chip is used to receive and process ultrasonic echo signals as well as give feedback to the master chip.
G-V-S Port
G-V-S port allows outer devices control.
Result
We can see the distance between sonar:bit and the object is displayed on micro:bit in real-time. The unit is centimeters.
Aoolication
Click to open Makecode online editor.
Write your program to assign the returned value of P2 to variable distance and display it on micro:bit screen.
