I am Tycho from Holland, I have got a flow sensor which won’t work on a Raspberry PI + GrovePI+.
It is the Flow Sensor YF-S402 G1/8 (https://www.seeedstudio.com/item_detail.html?p_id=1346).
I have tried it with the example/library from GrovePI (https://github.com/DexterInd/GrovePi/blob/master/Software/Python/grove_flow_read.py) of his bigger brother the YF-S402 G1/4 (http://digitalmeans.co.uk/shop/water_flow_sensor-g25-yfs402).
I also have tried to directly read the digitalPort (2 -> also connected to D2), then I get “0” and when I blow trough it some “1” go trough a spam of “0”. From within Python I can’t read it fast enough to see all the pulses on the GrovePI+ port…
Thank you in advance,
