WeatherRack/RJ11-Interface Board/ADS1115 Wiring....

Okay, I have everything working. Here is my wiring.  This isn't the only way to wire this setup, but it's how I chose to do it.  You can use any GPIOs you wish for the rain bucket and anemometer.




Once everything was wired-up, I used the following script to test the anemometer and rain bucket. (You need to have gpiozero library installed)

from gpiozero import Button

wind_speed_sensor = Button(5) #GPIO 5
wind_count = 0
rain_sensor = Button(26)  #GPIO 26
rain_count = 0

def wind():
   global wind_count
   wind_count = wind_count + 1
   print("wind" + str(wind_count))

wind_speed_sensor.when_pressed = wind

def rain():
   global rain_count
   rain_count += 1
   print("rain" + str(rain_count))
   
rain_sensor.when_pressed = rain

The output should look like this.  Every time the rain bucket is tipped or the anemometer completes one revolution, you will see the number increment.



To test the Wind Vane I used a script I found on SwitchDoc's git: github.com/switchdoclabs/SDL_Pi_Grove4Ch16BitADC  This was by far the simplest way I found to test the Wind Vane and the ADS1115. It didn't require editing the scripts or installing libraries.  Just download the zip or clone the git and extract/run.

#!/usr/bin/python

#SwitchDoc Labs May 2016
# reads all four channels from the Grove4Ch16BitADC Board in single ended mode
# also reads raw values
#
import time, signal, sys
sys.path.append('./SDL_Adafruit_ADS1x15')

import SDL_Adafruit_ADS1x15
def signal_handler(signal, frame):
       print( 'You pressed Ctrl+C!')
       sys.exit(0)
signal.signal(signal.SIGINT, signal_handler)

ADS1115 = 0x01 # 16-bit ADC

# Select the gain
gain = 6144  # +/- 6.144V
#gain = 4096  # +/- 4.096V
# gain = 2048  # +/- 2.048V
# gain = 1024  # +/- 1.024V
# gain = 512   # +/- 0.512V
#gain = 256   # +/- 0.256V

# Select the sample rate
#sps = 8    # 8 samples per second
# sps = 16   # 16 samples per second
# sps = 32   # 32 samples per second
# sps = 64   # 64 samples per second
# sps = 128  # 128 samples per second
sps = 250  # 250 samples per second
# sps = 475  # 475 samples per second
# sps = 860  # 860 samples per second

# Initialise the ADC using the default mode (use default I2C address)
adc = SDL_Adafruit_ADS1x15.ADS1x15(ic=ADS1115)
while (1):
# Read channels  in single-ended mode using the settings above
print ("--------------------")
voltsCh0 = adc.readADCSingleEnded(0, gain, sps) / 1000
rawCh0 = adc.readRaw(0, gain, sps)
print ("Channel 0 =%.6fV raw=0x%4X dec=%d" % (voltsCh0, rawCh0, rawCh0))
voltsCh1 = adc.readADCSingleEnded(1, gain, sps) / 1000
rawCh1 = adc.readRaw(1, gain, sps)
print ("Channel 1 =%.6fV raw=0x%4X dec=%d" % (voltsCh1, rawCh1, rawCh1))
voltsCh2 = adc.readADCSingleEnded(2, gain, sps) / 1000
rawCh2 = adc.readRaw(2, gain, sps)
print ("Channel 2 =%.6fV raw=0x%4X dec=%d" % (voltsCh2, rawCh2, rawCh2))
voltsCh3 = adc.readADCSingleEnded(3, gain, sps) / 1000
rawCh3 = adc.readRaw(3, gain, sps)
print ("Channel 3 =%.6fV raw=0x%4X dec=%d" % (voltsCh3, rawCh3, rawCh3))
print ("--------------------")
time.sleep(1)


The output should look like this. Every time you rotate the wind vane, the voltage should change.



Now it's time to write all of my code.  I'm building a custom weather station for my RC aircraft club so members can check the conditions before they come out and see the real-time data on a 32" TV at the field.

Thanks for listening as I sorted through this learning experience.   I hope this helps someone if they need this information in the future.
