Gravity SCI DAQ Question...
Tyler.McVety 2025-06-18 08:59:10 133 Views2 Replies Hey everyone - hoping someone can help me. I am trying to connect two analog sensors (Piezo and Analog Sound Sensor) to the Gravity SCI DAQ but I am not sure how…? I can easily connect one via a 3 pin to 3 pin cable on input port A1, but the other two ports are 4 pin.. What am I missing?
If you're connecting a Piezo sensor:
Red → VCC (Pin 1)
Black → GND (Pin 2)
Yellow (Signal) → SDA (Pin 3)
You can use male jumper wires or modify a 4-pin Gravity cable.
ahsrab.rifat @<a href="https://geometrydash-lite.org/"> geometry dash lite</a> Hey! I totally get how confusing those different pin configurations can be. It sounds like you've got the right idea with A1 for one sensor, but those 4-pin ports (A2 and A3, I assume?) are likely designed for Gravity I2C sensors or potentially digital sensors that need power, ground, and two data lines.
What you're probably missing is a way to adapt your 3-pin analog sensors to those 4-pin ports, or perhaps a different port on the DAQ itself. Sometimes, a DAQ will have dedicated 3-pin analog inputs for multiple sensors, but if not, you might need a specific adapter cable or breakout board that converts the 4-pin port into multiple 3-pin analog inputs. It's worth checking the Gravity SCI DAQ's manual or product page closely to see how they intend for multiple analog sensors to be connected beyond A1. Good luck!
