Description:
This sealed digital temperature probe lets you precisely measure temperatures in wet environments with a simple 1-Wire interface. The DS18B20 provides 9 to 12-bit (configurable) temperature readings from the onboard digital-to-analog converter, over a 1-Wire interface, so that only one wire (and ground) needs to be connected from a central microprocessor.

What I am using it for:
This will measure the water temperature in my saltwater marine fish tank. I will use 2 sensors to monitor 2 tanks, and a different temperature sensor to monitor the room temperature.

Usage:
You can connect multiple ones to the same pin, each one has a unique 64-bit ID burned in at the factory to differentiate them.
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.
A 4.7k resistor, is required as a pullup from the DATA to VCC line when using the sensor.

Description:
This is a breakout board for the incredibly small TMP102 digital temperature sensor. The TMP102 is a digital sensor (I2C a.k.a. TWI), has a resolution of 0.0625°C, and is accurate up to 0.5°C. The sensor requires very low-current, and is loaded with features.
Communication with the TMP102 is achieved through a two-wire serial interface. There is no on-board voltage regulator, so supplied voltage should be between 1.4 to 3.6VDC. Filtering capacitors and pull-up resistors are included as shown.

Usage:
Being digital, it is not necessary to take an average of 5 or so readings as is commonly done with analog sensors.
If this temperature sensor outputs a digital signal why is it connected to the analog inputs of the Arduino?
That is a great question! The answer is that most of the I/O pins on modern microcontrollers can be used for multiple purposes. Those particular analog pins are also used by the ATmega’s I2C (“Wire”) bus interface. When you use the Wire library, those pins cease being analog inputs, and are instead used for I2C communications. See the Arduino site’s Wire library reference page for more information. (comment link)
Can these be cascaded on one bus? That is, can I connect 4 of these on a single bus and connect them to a netduino? I can’t remember if the i2c lets you do that or not…
Yep, I2C is designed to accommodate multiple devices on the same bus, as long as all the devices have different addresses. The ADDR pin on this part allows it to be set to one of four possible addresses (see the datasheet on how to do this). So as long as you configure each one to have a different address, you’ll be able to talk to four of them on the same bus. (comment link)

Description:
MinipH - A pH interface for Arduino or Raspberry Pi projects by SparkysWidgets.
MinipH pH interface is a very cost effective solution for adding pH sensing capability to any project. MinipH uses a popular and proven 12 bit ADC that is very easy to work with, precise, and reliable, taking measurements is a snap. This makes it an ideal addition to any electronic tool box, especially those that need water quality sensors! Designed to be easily integrated with projects using either a breadboard(standard .1″ header) or even use a Seeed Grove connector! This is an open source hardware project and all files can be found on MinipH’s Project page or directly on my GitHub!

This will measure the pH of my Saltwater fish tank.
Usage:
The usage of the device is very straightforward and example code is provided, the gist of it is to simply ask the ADC for its value over standard I2C (both fast and slow modes) and assemble the bytes to recreate the 12bit number. Post processing is the standard pH calculations that can be found both here and on a few various other websites out there (although we all tend to calculate pH ever so slightly, I suspect the end results are all similar though).
SparkysWidgets has already uploaded a decent example on how to implement ph readings from a MinipH board to my github, and I will also include it here as well!
As a side note the ADC does about ~28.8KSPS giving us more then enough data points and bandwidth to be able to oversample and decimate, although with the quality of the 12 bit reading it gives already it would really be an overkill at this point (I am sure someone will anyway!)
