This...
Multifunction DHT11 LM35 Temperature Humidity Easy Module Shield for Arduino UNO
The board is designed for beginners in Arduino, with various components available that makes you build more than 10 projects easily. You won’t have to solder or connect anything at all, just plug it in a shield and start coming up with various simple examples rather than dealing with cables, sens...
MPL3115A2 - I2C Barometric Pressure/Altitude/Temperature Sensor
The MPL3115A2 is a precision barometric pressure, altitude, and temperature sensor from NXP (formerly Freescale) that communicates over I2C. With 1.5 Pa resolution, it can resolve altitude changes as small as 0.3 m and includes a built-in altimeter calculation — no external calibration or manual ...
Gravity: Analog Infrared CO2 Sensor For Arduino (0~5000 ppm)
The concentration of carbon dioxide (0.03% usuallly) is related to daily life. Recently, there's a study showing that the atmospheric CO2 content has reached 0.0385% (385 ppm) which is the highest value since 2.1 million years. The raise of atmospheric CO2 content to some extent results in gl...
SparkFun Infrared Temperature Breakout - TMP006
This is not your typical temperature sensor. The TMP006 Breakout can measure the temperature of an object without making contact with it. By using a thermopile to detect and absorb the infrared energy an object is emitting, the TMP006 Breakout can determine how hot or cold the object is. The TMP0...
LilyPad Temperature Sensor
Detecting temperature changes has never been easier. The MCP9700 is a small thermistor type temperature sensor. This sensor will output 0.5V at 0 degrees C, 0.75V at 25 C, and 10mV per degree C. Doing an analog to digital conversion on the signal line will allow you to establish the local ambient...
Infrared Emitter
An Infrared emitter, or IR emitter, is a source of light energy in the infrared spectrum. This little part is a light emitting diode (LED) that is used in order to transmit infrared signals from a remote control. This simple device operates at 940nm and works well for generic IR systems. This emi...
DS18B20 Digital temperature sensor + extras
These 1-wire digital temperature sensors are fairly precise (±0.5°C over much of the range) and can give up to 12 bits of precision from the onboard digital-to-analog converter. They work great with any microcontroller using a single digital pin, and you can even connect multiple ones to the s...
MPL115A2 - I2C Barometric Pressure/Temperature Sensor
This pressure sensor from Freescale is a great low-cost sensing solution for measuring barometric pressure. At 1.5 hPa resolution, it's not as precise as our favorite pressure sensor, the BMx280 series, which has up to 0.03 hPa resolution so we don't suggest it as a precision altimeter. Howeve...
