SparkFun Triple Axis Accelerometer Breakout – MMA7361

This is a breakout board for Freescale’s MMA7361L three-axis analog MEMS accelerometer. The sensor requires a very low amount of power and has a g-select input which switches the accelerometer between ±1.5g and ±6g measurement ranges. Other features include a sleep mode, signal conditioning, a 1-pole low pass filter, temperature compensation, self test, and 0g-detect which detects linear freefall. Zero-g offset and sensitivity are factory set and require no external devices.

This breadboard friendly board breaks out every pin of the MMA7361L to a 9-pin, 0.1″ pitch header. The sensor works on power between 2.2 and 3.6VDC (3.3 Volt optimal), and typically consumes just 400µA of current. All three axes have their own analog output.

  • Two selectable measuring ranges (±1.5g, ±6g)
  • Breadboard friendly – 0.1″ pitch header
  • Low current consumption: 400 µA
  • Sleep mode: 3 µA
  • Low voltage operation: 2.2 Volt – 3.6 Volt
  • High sensitivity (800 mV/g at 1.5g)
  • Fast turn on time (0.5 ms enable response time)
  • Self test for freefall detect diagnosis
  • 0g-Detect for freefall protection
  • Signal conditioning with low pass filter
  • Robust design, high shocks survivability

PIR Motion Sensor (JST)

This is a simple to use motion sensor. Power it up and wait 1-2 seconds for the sensor to get a snapshot of the still room. If anything moves after that period, the “Alarm” pin will go low. This unit works great from 5 to 12 Volt. The alarm pin is an open collector meaning you will need a pull up resistor on the alarm pin. The open drain setup allows multiple motion sensors to be connected on a single input pin. If any of the motion sensors go off, the input pin will be pulled low.

At their most fundamental level, PIR sensor’s are infrared-sensitive light detectors. By monitoring light in the infrared spectrum, PIR sensors can sense subtle changes in temperature across the area they’re viewing. When a human or some other object comes into the PIR’s field-of-view, the radiation pattern changes, and the PIR interprets that change as movement. All that’s left for us to connect is three pins: power, ground, and the output signal.

NeoPixels

The WS2812 Integrated Light Source, or NeoPixel in Adafruit parlance, is the latest advance in the quest for a simple, scalable and affordable full-color LED. Red, green and blue LEDs are integrated alongside a driver chip into a tiny surface-mount package controlled through a single wire. They can be used individually, chained into longer strings or assembled into still more interesting form-factors.

NeoPixels don’t just light up on their own; they require a microcontroller, such as Arduino, and some programming. We provide some sample code to get you started. To create your own effects and animation, you’ll need some programming practice. If this is a new experience, work through some of the beginning Arduino tutorials to get a feel for the language.

NeoPixel Stick – 8 x 5050 RGB LED

Make your own little LED strip arrangement with this stick of NeoPixel LEDs. We crammed 8 of the tiny 5050 smart RGB LEDs onto a PCB with mounting holes and a chainable design. Use only one microcontroller pin to control as many as you can chain together. Each LED is addressable as the driver chip is inside the LED. Each one has constant current drive so the color will be very consistent even if the voltage varies, and no external choke resistors are required making the design slim. Power the whole thing with 5VDC and you’re ready to rock. The LEDs are “Chainable” by connecting the output of one stick into the input of another. There is a single data line with a very timing-specific protocol.

Pololu 5 Volt Step-Up Voltage Regulator U1V10F5

This tiny U1V10F5 switching step-up voltage regulator efficiently generates 5 Volt from input voltages as low as 0.5 Volt. Unlike most boost regulators, the U1V10F5 automatically switches to a linear down-regulation mode when the input voltage exceeds the output.

Ultrasonic Distance Sensor – HC-SR04 (5 Volt)

This is the HC-SR04 ultrasonic distance sensor. This economical sensor provides 2 Centimetres to 400 Centimetres of non-contact measurement functionality with a ranging accuracy that can reach up to 3 Millimetres. Each HC-SR04 module includes an ultrasonic transmitter, a receiver and a control circuit. There are only four pins that you need to worry about on the HC-SR04: VCC (Power), Trig (Trigger), Echo (Receive), and GND (Ground). This sensor has additional control circuitry that can prevent inconsistent “Bouncy” data depending on the application.

GPS Receiver – GP-20U7

The GP-20U7 is a compact GPS receiver with a built-in high performances All-In-One GPS chipset. The GP-20U7 accurately provides position, velocity, and time readings as well possessing high sensitivity and tracking capabilities. Thanks to the low power consumption this receiver requires, the GP-20U7 is ideal for portable applications such as tablet PCs, smart phones, and other devices requiring positioning capability. This 56-Channel GPS module, that supports a standard NMEA-0183 and uBlox 7 protocol, has low power consumption of 40mA@3.3V (max), an antenna on board, and -162dBm tracking sensitivity. With 56 channels in search mode and 22 channels “All-In-View” tracking, the GP-20U7 is quite the work horse for its size.

SparkFun Environmental Combo – CCS811/BME280

The SparkFun CCS811/BME280 Environmental Combo Breakout takes care of all your atmospheric-quality sensing needs with the popular CCS811 and BME280 ICs. This unique breakout provides a variety of environmental data, including barometric pressure, humidity, temperature, TVOCs and equivalent eCO2 levels.

The CCS811 is an exceedingly popular sensor, providing readings for equivalent eCO2 in the parts per million (PPM) and total volatile organic compounds in the parts per billion (PPB). The CCS811 also has a feature that allows it to fine-tune its readings if it has access to the current humidity and temperature. Luckily for us, the BME280 provides humidity, temperature and barometric pressure. This allows the sensors to work together to give us more accurate readings than they’d be able to provide on their own. We also made it easy to interface with them via I2C.

SparkFun IR Receiver – TSOP85

This is a very small infrared receiver based on the TSOP85 receiver from Vishay. This receiver has all the filtering and 38kHz demodulation built into the unit. Simply point a IR remote at the receiver, hit a button, and you’ll see a stream of 1s and 0s out of the data pin.

SparkFun Digital Temperature Sensor – TMP102

The TMP102 is an easy-to-use digital temperature sensor from Texas Instruments. The TMP102 breakout allows you to easily incorporate the digital temperature sensor into your project. While some temperature sensors use an analog voltage to represent the temperature, the TMP102 uses the I2C bus of the Arduino to communicate the temperature. Needless to say, this is a very handy sensor that doesn’t require much setup.

The TMP102 is capable of reading temperatures to a resolution of 0.0625°C, and is accurate up to 0.5°C. The breakout has built-in 4.7k Ohm pull-up resistors for I2C communications and runs from 1.4V to 3.6V. I2C communication uses an open drain signaling, so there is no need to use level shifting.

SparkFun Line Sensor QRE1113 (Analog)

This version of the QRE1113 breakout board features an easy-to-use analog output, which will vary depending on the amount of IR light reflected back to the sensor. This tiny board is perfect for line sensing applications and can be used in both 3.3V and 5V systems.

The board’s QRE1113 IR reflectance sensor is comprised of two parts – an IR emitting LED and an IR sensitive phototransistor. When you apply power to the VCC and GND pins the IR LED inside the sensor will illuminate. A 100 Ohm resistor is on-board and placed in series with the LED to limit current. A 10k Ohm resistor pulls the output pin high, but when the light from the LED is reflected back onto the phototransistor the output will begin to go lower. The more IR light sensed by the phototransistor, the lower the output voltage of the breakout board.

These sensors are widely used in line following robots, white surfaces reflect much more light than black, so, when directed towards a white surface, the voltage output will be lower than that on a black surface.

Pololu Carrier for MQ Gas Sensors

This carrier board is designed to work with any of the MQ-series gas sensors, simplifying the interface from 6 to 3 pins—ground, power and analog voltage output—that are broken out with a 0.1″ spacing, making the board compatible with 0.1″ headers and standard breadboards and perfboards. This board has two mounting holes and provides convenient pads for mounting the gas sensor’s required sensitivity-setting resistor.

Alcohol Gas Sensor – MQ-3

This alcohol sensor is suitable for detecting alcohol concentration on your breath, just like your common breathalyzer. It has a high sensitivity and fast response time. Sensor provides an analog resistive output based on alcohol concentration.

How does this relate to the breath? It turns out that there is a standard conversion from breath alcohol content to BAC that is employed by commercial breathalyzers. Our formula for calculating BAC from the alcohol measured in the breath is:

% BAC = Breath mg/L * 0.21
