## Questions & Answers

**Q: Every turbidity tester costs $ 250+, so how does this sensor is priced $ 15?**
A: This sensor cannot be used as professional equipment due to the low-precision, you can use it in experimental project and laboratory measurements.

**Q: Is the dac pcb necessary if i just want to use it in analog mode with my arduino?**
A: Yes, you need to simulate the pattern with A

**Q: Does this come with the cable for connecting to arduino?**
A: It comes with a gravity 3-pin female cable, which will be easy to connect to our IO expansion shield, if your arduino is UNO, you still need to use three more male-male jumper wire.

**Q: will this work on 3.3V as well?**
A: No, this analog turbidity sensor needs to operate at 5V.
