Waterproof DS18B20 Digital temperature sensor Resistor (Waterproof DS18B20 temp)
Description:

This is a pre-wired and waterproofed version of the DS18B20 sensor.  Handy for when you need to measure something far away, or in wet  conditions. While the sensor is good up to 125°C the cable is jacketed  in PVC so we suggest keeping it under 100°C. Because they are digital,  you don't get any signal degradation even over long distances! These  1-wire digital temperature sensors are fairly precise (±0.5°C over much  of the range) and can give up to 12 bits of precision from the onboard  digital-to-analog converter. They work great with any microcontroller  using a single digital pin, and you can even connect multiple ones to  the same pin, each one has a unique 64-bit ID burned in at the factory  to differentiate them. Usable with 3.0-5.0V systems.

The only  downside is they use the Dallas 1-Wire protocol, which is somewhat  complex, and requires a bunch of code to parse out the communication. If  you want something really simple, and you have an analog input pin,  the TMP36 is trivial to get going.

We toss in a 4.7k resistor, which is required as a pullup from the DATA to VCC line when using the sensor.

Adafruit ADS1015 12-Bit ADC (ADS1015 12-Bit ADC)
Description:

The Raspberry Pi does not feature an Analog-to-Digital Converter (ADC), so if you want to measure analogue singals, you'll need this 12-Bit ADC!

The Adafruit 4-Channel I2C 12-Bit ADC is a high-precision ADC and features the ADS1015 chip, which provides 12-bit precision at 3300 samples/second over I2C. The chip can be configured as 4 single-ended input channels, or two differential channels. As a nice bonus, it even includes a programmable gain amplifier,with up to x16, to help boost smaller single/differential signals to the full range. We like this ADC because it can run from 2V to 5V power/logic, can measure a large range of signals and its super easy to use. It is a great general purpose 12 bit converter. 

The chip's fairly small so it comes on a breakout board with ferrites to keep the AVDD and AGND quiet and interfacing is done via I2C. The address can be changed to one of four options (see the datasheet table 5 in downloads below) so you can have up to 4 ADS1015's connected on a single 2-wire I2C bus for 16 single ended inputs. 
 
To get you started, we have example code for the Raspberry Pi - Simply connect GND to ground, VDD to your logic power supply, and SCL/SDA to your microcontroller's I2C port and run the example code to start reading data.
 
The Adafruit 4-Channel I2C 12-Bit ADC Features:
  • Wide Supply Range: 2.0V to 5.5V
  • Low Current Consumption: Continuous Mode: Only 150µA Single-Shot Mode: Auto Shut-Down
  • Programmable Data Rate: 128SPS to 3.3kSPS
  • Internal Low-Drift Voltage Reference
  • Internal Oscillator
  • Internal PGA
  • I2C Interface: Pin-Selectable Addresses
  • Can run from 2V to 5V power/logic
  • Measures a large range of signals and is super easy to use.
  • 12-bit precision at 3300 samples/second over I2C.
  • Configurable as 4 single-ended input channels, or two differential channels.
  • Includes a programmable gain amplifier, up to x16, to help boost up smaller single/differential signals to the full range.
  • Breakout Board equipped with ferrites to keep the AVDD and AGND quiet

  • Data Acquisition
  • Battery Operated Systems

How-To

The following sample assumes that you're running the latest official Raspbian distribution, that you're logged in as root and that you haven't yet customized Raspbian to use SPI from a Python script. By default, the kernel module managing SPI communications is not loaded on Raspbian, so let's ensure that the 'spidev' device is available.

[email protected]:/# lsmodModule                  Size  Used by  snd_bcm2835            12808  0  snd_pcm                74834  1 snd_bcm2835  snd_seq                52536  0  snd_timer              19698  2 snd_seq,snd_pcm  snd_seq_device          6300  1 snd_seq  snd                    52489  5 snd_seq_device,snd_timer,snd_seq,snd_pcm,snd_bcm2835  snd_page_alloc          4951  1 snd_pcm  

If 'spidev' device is not listed, we need to remove it from the kernel module 'blacklist' so that it's automatically loaded on the next boot:

[email protected]:/# nano /etc/modprobe.d/raspi-blacklist.conf  

Put a hash character in front of the 'blacklist spi-bcm2708' statement and save the file:

#blacklist spi-bcm2708  

then, manually load the SPI device:

[email protected]:/# modprobe spidev  

The command should just complete without returning an error. Validate the list of modules:

[email protected]:/# lsmod  Module                  Size  Used by  spi_bcm2708             4401  0  spidev                  5136  0  snd_bcm2835            12808  0  snd_pcm                74834  1 snd_bcm2835  snd_seq                52536  0  snd_timer              19698  2 snd_seq,snd_pcm  snd_seq_device          6300  1 snd_seq  snd                    52489  5 snd_seq_device,snd_timer,snd_seq,snd_pcm,snd_bcm2835  snd_page_alloc          4951  1 snd_pcm  

The 'spidev' device should now be available.

Next, install the 'git' package. It will be needed to install other packages from Github.

apt-get install git-core  

Install the 'python-dev' package. It will be needed to compile the 'py-spidev' package.

apt-get install python-dev  

Download and compile the 'py-spidev' package.

[email protected]:/# cd /home  [email protected]:/home# git clone git://github.com/doceme/py-spidev  [email protected]:/home# cd py-spidev/  [email protected]:/home# python setup.py install  

At this point, SPI is available from Python 2.7. Assuming that you have wired the MCP3008 to the Raspberry Pi's SPI bus using CE0 as the 'chip select' pin, you can read all eight analog inputs using the following Python script.

[email protected]:/home# nano adc.py  

Paste the script below in the editor and save it.

import spidev  import time    spi = spidev.SpiDev()  spi.open(0,0)    # read SPI data from MCP3008 chip, 8 possible adc's (0 thru 7)  def readadc(adcnum):          if ((adcnum > 7) or (adcnum < 0)):                  return -1          r = spi.xfer2([1,(8 adcnum)<<4,0])          adcout = ((r[1]&3) << 8)   r[2]          return adcoutwhile True:          for adcInput in range(0,8):                  print "ADC(", adcInput,")=", readadc(adcInput)          time.sleep(1)  

To execute the script

[email protected]:/home# python adc.py  

Sample output using a 10K Ohm trimpot connected to the ADC's pin 3 and all other pins pulled down to ground using a 10k resistor.

ADC( 0 )= 0  ADC( 1 )= 0  ADC( 2 )= 0  ADC( 3 )= 507  ADC( 4 )= 0  ADC( 5 )= 0  ADC( 6 )= 0  ADC( 7 )= 0  

Credits go to Jeremy for his work on the 'py-spidev' Python module which makes working with the MCP3008 straight forward. Alternatively, checkout wiringPi's SPI functions if you prefer using a 'C' API.
