In a way, the magic of a soil moisture sensor’s functionality boils down to a simple RC circuit. But of course, in practice there is a bit more to it than that. [rbaron] explains exactly how ...

Around the Hackaday bunker, any plant other than a cactus has a real chance of expiring due to thirst. Perhaps we should build some of [MakersFunDuck]’s Moisture Duck boards. As you can see in the ...

Designing a sensing application involves circuitry for amplification of a sensor signal, its conditioning and, in most cases, conversion into digital form. This is achieved conventionally by using ...

Smart home automation is the ultimate life hack, in my humble opinion. Whether for efficiency, accessibility, nerding out, or just plain laziness, all you need are smart home devices and a little ...

Tired of encoders that take space and need maintenance? A sensor design makes motion systems smaller and easier to use.
