Thermocouples : ELECTRICAL INSTRUMENTATION SIGNALS
An interesting phenomenon applied in the field of instrumentation is the Seebeck effect, which is the production of a small voltage across the length of a wire due to a difference in temperature along that wire.
Sometime back, I ordered a HH10D, humidity sensor from sparkfun with the idea of integrating this sensor with an Arduino Pro (3.3V).

chipKIT Project 2: Temperature and relative humidity logger
This project is about building a PC-based temperature and relative humidity logger using the chipKIT Uno32 board and the DHT11 sensor.Circuit Note | CN0206 | Complete Thermocouple Measurement System Using the AD7793 24-Bit Sigma-Delta ADC
The circuit shown in Figure 1 is a complete thermocouple system based on the AD7793 24-bit sigma-delta (Σ-Δ) analog-to-digital converter (ADC). The AD7793 is a low power, low noise, complete analog front end for high precision measurement applications. The device includes a programmable gain amplifier (PGA), an internal reference, an internal clock, and excitation currents, thereby greatly simplifying the thermocouple system design. The AD7793 consumes only 500 μA maximum, making it suitable for any low power application, such as smart transmitters where the complete transmitter must consume less than 4 mA. The AD7793 has a power-down option. In this mode, the complete ADC, along with its auxiliary functions, is powered down so that the part consumes 1 μA maximum.#include //SSD
