I ve been trying to make mesures of a distance with ultrasound (I've tried the sensor sonar:bit V1.6, VMA306 and SRF005) . The mesures the micro:bit gives me are always 0.64 times the real distance mesured with a ruler. ( I did tests from 5cm to 200 cm)

Could you tell me why do i find this proportional coefficent equal to 0,64 ?

Bests regards,

Emily

For the same ultrasonic sensor, test data with Arduino code was normal, while test data with microbit code was wrong.
After oscilloscope test, I found that the data returned by pulseIn() function was wrong.

Hi, thanks for developing this extension.
I think it is better to add millimeters (caculated to hundreadths place value) unit in case of measuring closer things.

Check the suggestion please.

Hi,
with the HC-SR04 ultrasonic distance sensor and the pxt.microbit,org editor for the BBC Microbit the Package don't work.

The output is always "0".

The hardware works fine (tested with an Arduino Uno)

Shure that this package should work?

Best regards
