Hi there, I'm working on my first Raspberry Pi project now trying to build the Smart Garden System. I have everything built and I'm trying to activate the different components now. I thought I'd start with the Moisture Sensor so the water pump will know when to start and stop. However when I run TestGrove4Ch16BitADC.py I get the error:
Traceback (most recent call last): File "TestGrove4Ch16BitADC.py", line 13, in <module> from Adafruit_ADS1x15 import ADS1x15 ImportError: No modudle named Adafruit_ADS1x15
I'm very much in over my head here because the instructions seemed to end abruptly in the manual after it told me to read the Readme.md files for installation instructions. It was all going well up until that point.
For instance I tried to install the 8 Pixel Strip but the instructions after installing Scons got a bit fuzzy. (I don't know where the scons source directory is or how to test it.) But alas, one thing at a time. How do I install the moisture sensor? And what does that eror mean? I must have done something wrong installing the Adafruit (although that seemed to go fine with zero errors). Thanks for any help.
Thanks John. I tried this and I seem to get a never ending error that says:
Plant #1: 3.29/C1 ADS1115_Ext1 Not Present ADS1115_Ext2 Not Present
It also says Remote I/O error and error accessing 0x49: Check your I2C address. (I will double check everything is in the right spot but I was pretty sure it was already.)
Is the moisture sensor the device that uses the 3 wire cable? It's longer than the others and doesn't have a white wire, just black, red, and yellow. Thanks again, I know I chose an advanced project to be my first one but hey I like a challenge. :-)
Moisture Sensor is plugged into spot A1 on the 4 Channel ADC and the connection seems good. I did notice when I run testAllSensors.py the Extender Devices category says that ADS115_Ext1 and Ext2 (and the two other extender devices) read as Not Present. Is the Moisture Sensor considered an extender device?
