The NXP Precision 9DoF breakout combines two of the best motion sensors we've tested here at Adafruit: The FXOS8700 3-Axis accelerometer and magnetometer, and the FXAS21002 3-axis gyroscope. These two sensors combine to make a nice 9-DoF kit, that can be used for motion and orientation sensing. In particular, we think this sensor set is ideal for AHRS-based orientation calculations: the gyro stability performance is superior to the LSM9DS0,...

Infrared (IR) break-beam sensors are a simple way to detect motion. They work by having an emitter side that sends out a beam of human-invisible IR light, then a receiver across the way which is sensitive to that same light. When something passes between the two, and its not transparent to IR, then the 'beam is broken' and the receiver will let you know. Compared to PIR sensors, breakbeams are faster and allow better control of where you...

CdS cells are little light sensors. As the squiggly face is exposed to more light, the resistance goes down. When its light, the resistance is about 5-10KΩ, when dark it goes up to 200KΩ. To use, connect one side of the photo cell (either one, its symmetric) to power (for example 5V) and the other side to your microcontroller's analog input pin. Then connect a 10K pull-down resistor from that analog pin to ground. The voltage on...

Need to measure something damp? This epoxy-coated precision 1% 10K thermistor is an inexpensive way to measure temperature in weather or liquids. The resistance in 25 °C is 10K (+- 1%). The resistance goes down as it gets warmer and goes up as it gets cooler. For specific temperature-to-resistance, check the lookup table. These are often used for air conditioners, water lines, and other places where they can get damp. The PVC coating of the...

For precision temperature sensing, nothing beats a Platinum RTD. Resistance temperature detectors (RTDs) are temperature sensors that contain a resistor that changes resistance value as its temperature changes, basically a kind of thermistor. In this sensor, the resistor is actually a small strip of Platinum with a resistance of 100 ohms at 0°C, thus the name PT100. Compared to most NTC/PTC thermistors, the PT type of RTD is much most stable...

You can also solder a wire to the middle pad and create your own capacitive pad if the...

It does require a DC voltage to run, at 4.5-30VDC. It has reverse polarity protection in case you swap the power leads by accident. To use, simply connect the thin red wire to a positive supply, and the thin black wire to ground. Then tape the black thermistor bulb to whatever you want to...

This precision sensor from Bosch is the best low-cost sensing solution for measuring barometric pressure and temperature. Because pressure changes with altitude you can also use it as an altimeter! The sensor is soldered onto a PCB with a 3.3V regulator, I2C level shifter and pull-up resistors on the I2C pins. NEW! We now have a fully 5V compliant version of this board - a 3.3V regulator and a i2c level shifter circuit is included so you can use...

Humidity is notoriously difficult to measure. Some of the scientific and electronic considerations to measuring humidity include: analog to digital interface and external circuitry which might require op-amps or oscillator circuitry; temperature compensation adjustments to calculate dew point; calibration against a known humidity source; mounting, protection and response time in the real-world. If you're interested in the details see Tracy...

Laser break beam sensors are usually kind of cumbersome. They work by detecting an object breaking a laser beam - but you usually have to set up a laser on one end and a sensor on the other. Unless your sensor is big, it can easily get out of alignment. ...but not this break beam sensor. It has a light sensor+lens next to the laser to detect the reflected dot when the beam is broken, so it can sense when someone...
