I only need one Phidgets device to monitor the voltage level from a battery. The voltage level ranges from 9.0 to 14.5 volts. I don't want to invest $80.00 in the 1018 interface kit but would rather directly connect this one sensor to a RPI3. Can this direct connection be done? If so, how would I do it?
From what I can tell, the GPIO pins on the PI boards are all digital (true or false only), and to read the 1135 you'll need an analog input (0-5V). In order to do this with a PI you'll either need an ADC (analog-to-digital converter) or an I2C interface designed to read sensors on the I2C pins.
If you're looking for cheap alternatives, most Arduino boards come equipped with analog inputs. For small projects that have small programs, you can get an ATTiny85 for a few dollars that will read the 1135.
Thanx for the info. Yep, it appears that I need some sort of ADC converter to use the 1135_0 voltage sensor with a RPI. Thus, I've ordered the 1018 Interface board.
