Pretty much every modern car has some driver assistance feature, such as lane departure and blind-spot warnings, or adaptive cruise control. They’re all pretty cool, and they all depend on …read more Continue reading Fundamentals of FMCW Radar Help You Understand Your Car’s Point of View
Usually, when you need to sense something in a project, the answers are straightforward. Want to sense air temperature? There’s a sensor for that. Particulate content in the air? There’s …read more Continue reading Why Use a Sensor When a Pseudo-Sensor Will Do?
LEDs are a wonderful technology. You put in a little bit of power, and you get out a wonderful amount of light. They’re efficient, cheap, and plentiful. We use them …read more Continue reading You Can Use LEDs As Sensors, Too
Wait a second, read that title again. This isn’t a throwback 3D printing project at all. That’s “RepTrap” as in reptile trap, and it’s a pretty clever way to study …read more Continue reading RepTrap Keeps Watch Over Our Cold-Blooded Friends
The MAX30105 is an optical sensor capable of a great many things. It can sense particulate matter in the air, or pick up the blinking of an eye. Or, you …read more Continue reading This Air Particulate Sensor Can Also Check Your Pulse Rate
Bed sensors do sort of sound like a gimmick — after all, who cares whether someone is occupying the bed? But if you think about it, that information is quite …read more Continue reading Bed Sensors Do More Than You’d Think
With the increase in popularity of Internet of Things (IoT) devices and their need to communicate wirelessly, there’s been a corresponding explosion of wireless protocols to chose from. Of course …read more Continue reading Converting Bluetooth Sensors to Zigbee
If you’ve got a smart home, or you just want to know how soaked your garden is getting in the winter, you might want to measure rainfall. There are a …read more Continue reading Capacitive Rainmeter Measures The Sky Water Just Fine
If you need to send data from sensors, there are plenty of options, including a bewildering selection of wireless methods. Trouble is, most of those protocols require a substantial stack …read more Continue reading Simple CMOS Circuit Allows Power and Data Over Twisted-Pair Wiring
Here at Hackaday, we feature all kinds of projects, and we love them all the same. But some projects are a little easier to love than others, especially those that …read more Continue reading 3D Printing Improves Passive Pixel Water Gauge
