Attention !! Analog Sensor  !! Attention !! Unlike the Arduino, the Raspberry Pi doesn't provide an ADC (Analog Digital Converter) on its Chip. This limits the Raspbery Pi if you want to use a non digital Sensor. To evade this, use our Sensorkit X40 with the KY-053 module, which provides a 16 Bit ADC, which can be used with the Raspberry Pi, to upgrade it with 4 additional analog input pins. This module is connected via I2C to the Raspberry Pi. It measures the analog data and converts it into a digital signal which is suitable for the Raspberry Pi. So we recommend to use the KY-053 ADC if you want to use analog sensors along with the Raspberry Pi. For more information please look at the infosite: KY-053 Analog Digital Converter !! Attention !! Analog Sensor  !! Attention !! The program uses the specific ADS1x15 and I2C python-libraries from the company Adafruit to control the ADS1115 ADC. You can find these here: [https://github.com/adafruit/Adafruit-Raspberry-Pi-Python-Code] published under the  BSD-License [Link]. You can find the needed libraries in the lower download package. The program reads the current values of the input pins and outputs it at the terminal in [mV]. Additianal to that, the status of the digital pin will be shown at the terminal to show if the extreme value was exceeded or not. ######################################################################################## ### Copyright by Joy-IT ### Published under Creative Commons Attribution-NonCommercial-ShareAlike 3.0 Unported License ### Commercial use only after permission is requested and granted ### ### KY-053 Analog Digital Converter - Raspberry Pi Python Code Example ########################################################################################### # This code is using the ADS1115 and the I2C Python Library for Raspberry Pi # This was published on the following link under the BSD license # [https://github.com/adafruit/Adafruit-Raspberry-Pi-Python-Code] from Adafruit_ADS1x15 import ADS1x15 from time import sleep # import needed modules import time, signal, sys, os import RPi.GPIO as GPIO GPIO.setmode(GPIO.BCM) GPIO.setwarnings(False) # initialise variables delayTime = 0.5 # in Sekunden # assigning the ADS1x15 ADC Export: 16.06.2017 Copyright by Joy-IT - Published under CC BY-NC-SA 3.0 Page 156 of 214 KY-035 Bihor magnetic sensor module ADS1015 = 0x00 # 12-bit ADC ADS1115 = 0x01 # 16-bit # choosing the amplifing gain gain = 4096 # +/- 4.096V # gain = 2048 # +/- 2.048V # gain = 1024 # +/- 1.024V # gain = 512 # +/- 0.512V # gain = 256 # +/- 0.256V.
