Hello. I just purchased my first Arduino and I bought a sensor to play around with. It is a pressure sensor of the type BX-PSC19 made by the Chinese company Benxu.
The problem is I can't find any documentation about the sensor whatsoever.
On the manufacturers website it says "PSC19 can be easily amplified and assembled into the pressure transmitters with standard signal output." What is standard signal output?
The sensor has 4 wires, red, blue, yellow and white. Does this mean it might be using I2C? If so which wire does what?
Any help appreciated
