This alcohol sensor is suitable for detecting alcohol concentration on your breath, just like your common breathalyzer. It has a high sensitivit...

This is a steam(water)sensor from DFRobot. This steam sensor can be connected to the Arduino IO Expansion shield directly. The output voltage wi...

Three pin JST connector with red, black, and yellow colors. 5 inch wire outs. This cable comes fully assembled as shown and connects directly to...

This is a piezoresistive force sensor. The harder you press, the lower the sensor's resistance. Pressing lightly, the resistance changes from...

These are very thin variable potentiometers. By pressing down on various parts of the strip, the resistance linearly changes from 100Ohms to 10,000...

Small electret microphone. Useful in acoustic and audio applications. Documents: Datasheet Example Audio LED control project by Adam Greig

A simple flex sensor 4.5" in length. As the sensor is flexed, the resistance across the sensor increases. Patented technology by Spectra Symbol ...

The Spectacle Audio Board allows you to add sound from a microSD card to your Spectacle projects. Each board accepts a microSD card with sounds in ...

This is a small ambient light sensor that acts as an NPN transistor. The more the sensor is exposed to light, the stronger the base bias. Simple...

The Pololu MinIMU-9 v2 is a compact (0.8″ × 0.5″) board that combines ST’s L3GD20 3-axis gyroscope and LSM303DLHC 3-axis accelerometer and 3-axis m...

This board has been replaced by the newer MinIMU-9 v2 L3GD20 and LSM303DLHC carrier, which offers improved magnetic sensing resolution, a wider acc...

This is not your typical temperature sensor. The TMP006 Breakout can measure the temperature of an object without making contact with it. By using ...

These are very bright LEDs. The LEDs are so bright that it hurts to look directly at them. Please take a look at the pictures to get an idea of ...

The SparkFun Load Sensor Combinator is a bare PCB that combines four load sensors into a standard four-wire Wheatstone bridge configuration. If ...

Here comes DFRobot's new Analog Ambient Light Sensor for Arduino or Raspberry Pi. Brand new design and much more convenient to use. This sensor...
