If you're starting out, or just looking to experiment with new tech, a kit can be the way to go and it allows you to try out heaps of different sensors.

Accelerometers are the basis of all motion control. They allow you to sense both static and dynamic acceleration and are easy to integrate into your project.

Some important factors to take into account when buying an accelerometer for your project:

• Sensitivity (some have variable options)
• Resolution
• Communication method (eg. I2C or SPI)

Sound is all around us, and whether you just need a sound trigger, or a miniature microphone, we've got sensors for every project.

Perhaps you want to level up your project and integrate magnetic swipe cards or barcodes readers? You're in luck because we've got both!

Biometric data is all about capturing information about our bodies and we've got heart rate monitors, fingerprint scanners, muscle sensors, and more.

Capture the world around you with our range of camera sensors. Whether it's for a Raspberry Pi, or simple surveillance system, we've got you covered.

When a standard switch or resistive touch button doesn't cut it, capacitive touch is the slicker, easier to use option, from a single button to a multichannel array.

Finding out how much current your project is drawing can be incredibly important whether it's a wearable, portable project, or just to watch the power consumption.

Detecting distances is a foundation of autonomous and guided robotics. It doesn't matter how smart your robot is if he keeps running into things!

We've got two different technologies of distance sensors; Infrared and Ultrasonic. Both have their advantages and we've got options for both.

Encoders allow you to track rotation speed and measure wheel position using optical or magnetic sensors, and they're easy to use with your project.

Perhaps you're inspired by flex-sensing wearables? Either way, flex sensors can bring life to your project.

Whether it's detecting flammable gas, alcohol, or just small particles such as dust or smoke, our gas & smoke sensors are easy to get started with.

We've got pre-soldered modules, or sensors by themselves with a breakout board for easy integration with your project.

Gyroscopic sensors are handy little devices as they allow you to measure angular rotation with selectable resolutions using a standard microcontroller.

We've got two different boards which use the same chip, however, the Adafruit one has a nicer silkscreen guide and pin labelling if that's what your after. Alternatively, the Pololu board is just as good, but in a different form factor, without the fancy silkscreen.

IMUs (Inertial Measurement Unit) combine multiple sensors such as an accelerometer, gyroscope, and compass sensor to provide multi-axis motion tracking.

It's light that you can't see, but is all around you! Infrared technology is used in thermometers, distance sensors, remote controls, and heaps more.

Light sensors can be used for all kinds of applications from ambient levels and colour sensing, to proximity control and basic make/break circuits.

For projects such as aquariums, hydroponics, fountains, and more, being able to measure the water level, or flow rate can be incredibly valuable.

Magnetic fields are equal parts fun and useful. We've got compass sensors, hall-effect sensors, and reed switches to integrate with your next project.

Build your own coin-based machines using coin acceptor units. They can read different coins and accept or reject them based on programmable profiles.

Whilst strictly for educational use only, Geiger counters can used to measure the radiation from simple household items, such as a smoke detector.

How's the weather? Well, you may never know without some sensors for your next project, and we've got both analog and digital options covered.
