Adafruit MAX31865 RTD PT100 Amplifier
PT100 Cruisin'
by lady ada
To get precision and accuracy out of your PT100 RTD you must use an amplifier that is designed to read the low resistance. Better yet, have an amplifier that can automatically adjust and compensate for the resistance of the connecting wires. If you're looking for a great RTD sensor, today is your lucky day because we have a lovely Adafruit RTD Sensor Amplifier with the MAX31865 breakout for use with any 2, 3 or 4 wire PT100 RTD!

Adafruit MAX31856 Universal Thermocouple Amplifier
Now you can handle any kind of thermocouple!
by lady ada
Thermocouples are very sensitive, requiring a good amplifier with a cold-compensation reference, as well as calculations to handle any non-linearities. For a long time we've suggested our MAX31855K breakout, which works great but is only for K-type thermocouples. Now we're happy to offer a great new thermocouple amplifier/converter that can handle just about any type of thermocouple, and even has the ability to give you notification when the temperature goes out of range, or a fault occurs. Very fancy! This converter communicates over 4-wire SPI and can interface with any K, J, N, R, S, T, E, or B type thermocouple
Adafruit Si7021 Temperature + Humidity Sensor
Get the current ambient temperature and humidity
by lady ada
This lovely sensor for Silicon labs has ± 3% relative humidity measurements with a range of 0–80% RH, and ±0.4 °C temperature accuracy at a range of -10 to +85 °C. Great for all of your environmental sensing projects. It uses I2C for data transfer so it works with a wide range of microcontrollers.
Adafruit BMP280 Barometric Pressure + Temperature Sensor Breakout
Buld your next weather sensing system
by lady ada
Bosch has stepped up their game with their new BMP280 sensor, an environmental sensor with temperature and barometric pressure! This sensor is great for all sorts of weather/environmental sensing and can even be used in both I2C and SPI!
Calibrating Sensors
Get peak performance from all your sensors.
by Bill Earl
Most modern sensors perform quite well right out-of-the box. But the sensor is only part of the measurement system. For best accuracy in critical applications, you will want to calibrate.

Adafruit TMP007 Sensor Breakout
Thermopile temperature sensors let you measure without touching
by lady ada
Unlike most of the other temperature sensors we have, this breakout has a really cool IR sensor from TI that can measure the temperature of an object without touching it. The TMP007 is the latest thermopile sensor from TI, and is an update of the TMP006. The internal math engine does all the temperature calculations so its easier to integrate
Adafruit BMP183 SPI Barometric Pressure & Altitude Sensor
All the joy of a BMP085 - in SPI format!
by lady ada
The BMP183 is the next-generation of sensors from Bosch, and is the fraternal twin of the BMP180 - with a low altitude noise of 0.25m and the same fast conversion time. It has the same specifications, but uses SPI instead of I2C. This is great for users where there is an I2C address collision, they want more than one sensor on a single microcontroller, more flexibility on pin usage, or just prefer the simplicity of SPI.
Adafruit HTU21D-F Temperature & Humidity Sensor
Easy and precise temp and humidity monitoring
by lady ada
It's summer and you're sweating and your hair's all frizzy and all you really want to know is why the weatherman said this morning that today's relative humidity would max out at a perfectly reasonable 52% when it feels more like 77%. Enter the HTU21D-F Temperature + Humidity Sensor - the best way to prove the weatherman wrong!

Using Melexis MLX90614 Non-Contact Sensors
Tell temps without touching!
by lady ada
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!
by lady ada
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.
