The DHT22 is a step up from the older DHT11 and has some improved features.

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 over a 1-Wire interface, so that only one wire (and ground) needs to be connected from a central microprocessor.

This is a simple, 220 Ohm, 1/4th Watt, +/- 5% tolerance PTH resistor. Sold as single units...

These devices are made of a special ceramic material which changes resistance value rapidly with temperature change. They are commonly used to check thermal runaway with bipolar transistor amplifiers etc, but really have dozens of other uses. They are rugged and very reliable.

This is a stainless steel, Type-K Thermocouple probe. A thermocouple works by taking two wires made of dissimilar metals, connecting them at the two ends, and making a temperature gradient between one end and the other (a ‘hot’ end and a ‘cold’ one). Once this is achieved, a voltage potential is formed and current flows. One junction is held in the environment where the temperature of interest exists, this is known as the hot junction. The other junction, referred to as the cold junction, can typically be found in ICs that specialize in reading the temperatures detected by the thermocouple probe.

The TMP117 Precision Temperature Sensor is an I2C temperature sensor that will help you easily add temperature measurement and adjustment to your project. In addition to the obvious support for reading the temperature, the TMP117 can also monitor the temperature and alert you when corrective action needs to be taken.

The SparkFun MAX31855K Thermocouple Breakout is a simple 14-bit resolution, SPI-compatible, serial interface thermocouple digitizer that makes reading a wide range of temperatures possible. A thermocouple works by taking two wires made of dissimilar metals, connecting them at the two ends, and making a temperature gradient between one end and the other (a ‘hot’ end and a ‘cold’ one). Once this is achieved, a voltage potential is formed and current flows. The SparkFun Thermocouple Breakout takes a standard Type-K thermocouple in one end, digitizes the temperature measured and sends that data out the other end via a SPI interface, thereby interpreting the data and translating it for you to read!
