Sensors are awesome tools that can help measure, analyse, interact with and even predict the environment in which they’re placed, and what makes them really amazing is that they allow us to build machines, devices and robots that can understand the world around them, leading to ever-more functional, fun or just silly projects for us to enjoy.

Sensors are awesome tools that can help measure, analyse, interact with and even predict the environment in which they’re placed, and what makes them really amazing is that they allow us to build machines, devices and robots that can understand the world around them, leading to ever-more functional, fun or just silly projects for us to enjoy.
Within this section of DIYElectronics, we have Sensor Components and Sensor Modules for measuring and analysing a wide range of different factors, from rain detection sensors to barcode readers, and all of the sensors featured here are ones that we love, and often use within our many different projects. In fact, we very seldom acquire products that we wouldn’t want to use ourselves, and when it comes to sensing the environment and surrounding spaces, we believe that there is no such thing as too many options for customisation.
If you’ve always wanted to do projects like making your air-conditioner to turn on depending on the weather, creating a gesture-based coffee machine, automatically dose your pool to balance out pH levels, or simply want to equip your favourite little bot-buddy with more “eyes”, “ears” and other senses for interacting with the world, you’ve most certainly come to the right place!
