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)

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.

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.

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

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.
