Whether you're an agriculturalist, a professional meteorologist or a weather hobbyist, building your own weather station can be a really rewarding project. When you're measuring weather, however, you need some pretty specialized sensors. This kit represents the three core components of weather measurement: wind speed, wind direction and rainfall. None of the sensors in this kit contain active electronics, instead they use sealed magnetic reed switches and magnets so you'll need to source a...

"This is a breakout board for the Bosch BMP180 high-precision, low-power digital barometer. The BMP180 offers a pressure measuring range of 300 to 1100 hPa with an accuracy down to 0.02 hPa in advanced resolution mode. It’s based on piezo-resistive technology for high accuracy, ruggedness and long term stability. These come factory-calibrated, with the calibration coefficients already stored in ROM. What makes this sensor great is that it is nearly identical to its former rev, the...

A simple breakout PCB for the GP1A57HR photo interrupter (also known as a photogate, photodiode, or phototransistor). This PCB has three connections for PWR, GND, and Signal. When the gate is clear, SIG will be high (>4.9V). When the gate is blocked by a finger, writing utensil, food pellet, or anything else - SIG will go low ( Assembled picture is for reference only, board comes bare; photo interrupter and the 220Ω (330Ω, works as well) current limiting resistor are listed below.

The HM01B0 from Himax Imaging is an ultra low power CMOS Image Sensor that enables the integration of an “Always On” camera for computer vision applications such as gestures, intelligent ambient light and proximity sensing, tracking and object identification. The sensor allows the sensor to consume very low power of SparkFun Edge Development Board and comes with a ribbon cable that mates to the camera connector populated on the Edge board. The HM01B0 contains 320 x 320 pixel resolution and...

We've been using and selling Analog Devices' ADXL accelerometers for a good while now, and now we've found another great part in the series! The ADXL362 is a complete 3-axis MEMS acceleration measurement system that operates at extremely low power consumption levels. It measures both dynamic acceleration, resulting from motion or shock, and static acceleration, such as tilt. It's easy to communicate with the ADXL362 over SPI and built-in digital logic even enables autonomous operation for...

This is a glass, cylindrical RFID tag; it's very similar to those implanted into pets for identification purposes. But really guys, it's not for use inside your body. Please don't implant this thing...

This is a glass, cylindrical RFID tag; it's very similar to those implanted into pets for identification purposes. But really guys, it's not for use inside your body. Please don't implant this thing into yourselves. Each tag comes with a unique 32-bit ID code and is not reprogrammable. The carrier frequency of this tag is 125kHz, so it works great with our ID-3LA, ID-12LA and ID-20LA RFID readers. We tested this RFID tag with one of our ID-12LA readers and measured a maximum read distance of...

The Accelerometer sensor is an add-on for your RedBot that provides bump and motion detection. The sensor works by measuring acceleration forces on the x, y, and z axis. By measuring the amount of acceleration (or lack there of) your robot can get a better understanding of its movements. The sensor has two 2x3 headers (one male and one female) which connect directly to the RedBot Mainboard giving you the ability to stack another I2C sensor. Just use the included RedBot library to detect bumps...

The AH1815 is an integrated Hall-Effect non-latched sensor. That’s nice but what does it do? Holding a magnet near the sensor will cause the output pin to toggle. This makes for a robust presence sensor. A reed sensor also works nicely, but can be limited by the glass encapsulation and size. A Hall-Effect sensor is much smaller, but can handle less current than a reed switch. The AH1815 is a low-sensitivity, micro-power Omnipolar Hall effect switch IC, designed for portable and battery powered...

This S-Type load cell (sometimes called a strain gauge) can translate up to 200kg of pressure (force) into an electrical signal. Each load cell is able to measure the electrical resistance that changes in response and proportion to the strain (e.g., pressure or force) applied to the form. With this gauge you will be able to tell just how heavy an object is, if an object's weight changes over time, or if you simply need to sense the presence of an object by measuring strain or load applied to a...

A miniature snap-action switch, also trademarked and frequently known as a micro switch, is an electric switch that is actuated by very little physical force.Micro switches are very widely used; among their applications are appliances, machinery, industrial controls, vehicles, and many other places for control of electrical circuits. They are usually rated to carry current in control circuits only, although some switches can be directly used to control small motors, solenoids, lamps, or other...
