Using Melexis MLX90614 Non-Contact Sensors
Tell temps without touching!
This cyber-tronic looking sensor hides a secret behind it's glimmering eye. Unlike most temperature sensors, this sensor measures infrared light bouncing off of remote objects so it can sense temperature without having to touch them physically. Simply point the sensor towards what you want to measure and it will detect the temperature by absorbing IR waves emitted. Because it doesn't have to touch the object it's measuring, it can sense a wider range of temperatures than most digital sensors: from -70°C to +138°C It takes the measurement over an 90-degree field of view so it can be handy for determining the average temperature of an area.

Thermocouple
Lets use the Seebeck effect!
Thermocouples are best used for measuring temperatures that can go above 100 degC. This is a bare wires bead-probe which can measure air or surface temperatures. Most inexpensive thermocouples have a vinyl covering which can melt at around 200 degC, this one uses a fiberglass braid so it can be used in high temperature measurements such as heaters and ovens. This is a handy guide which covers thermocouple use including an Arduino library and example code.

TMP36 Temperature Sensor
Reading temperatures to 0.1 degree precision!
An analog temperature sensor is pretty easy to explain, its a chip that tells you what the ambient temperature is. This guide will show you how an analog temperature sensor works, how to wire one up, and some project examples.

Thermistor
Measure temperature using a resistor!
A thermistor is a thermal resistor - a resistor that changes its resistance with temperature. Technically, all resistors are thermistors - their resistance changes slightly with temperature - but the change is usually very very small and difficult to measure. Thermistors are made so that the resistance changes drastically with temperature so that it can be 100 ohms or more of change per degree! This guide will teach you how thermistors work, and how to wire them up and use them with your favorite microcontroller.
