VM125 Ultrasonic sensor

Modules General
1

Dear electronics-people,

Last week I bought the VM125 ( velleman.eu/products/view/?c … &id=355062 )
I really need the analog output with variable voltage (5V)… But I measure nothing more than 0.05V.
Because the datasheet is very very limited I don’t know what to do …

Can anybody help please?

The Buzzer, digital output and relay are doing it great …

Thanks !!

Ps: I had 2 modules with the same result

It is highly unlikely that the analog output of two modules would be defective.
Most likely you made a measuring error.
Also, please note that the output can supply 5mA max. If the impedance of the load is too low, the voltage will collapse.
As this is an assembled and tested product, it should be returned when defective.
Hereby a link to the diagram.
