Sometimes, projects start in somewhat unlikely places. This one began when [Istvan Raduly] scored a fake raven at a neighbor’s garage sale and decided to turn it into a thunder-and-lightning ...
Can an ESP32 detect people without cameras or motion sensors? Discover how Wi-Fi signal disturbances, CSI, and smart DSP enable real-time occupancy and mov ...
The ESP32 keeps finding new jobs in my house.
Learn how to repurpose your spare ESP32 boards into cost-effective presence detection sensors using the Tommy Sense ...
When you’re driving your car, you’re probably regularly looking at the speedometer to make sure you comply with the local speed limits. The method by which it works is simple enough: ...
As sensing technologies become increasingly multi- and inter-disciplinary, their role is rapidly evolving beyond signal detection. In this Viewpoint, five experts discuss emerging sensing paradigms, ...
Installing a smart water sensor can save you a lot of money and hassle. The top leak detectors we've tested immediately alert you to issues and even shut off your home's water supply. I’ve been ...
This is the SparkFun Arduino library for the Texas Instruments TMAG5273 low-power linear 3D Hall-effect sensor with I 2 C interface. This SparkFun Arduino Library for the Texas Instruments TMAG5273 ...
Abstract: This paper presents designing and implementing an Automatic room temperature control system using the Arduino and DHT11 sensor. The fan speed control system has also been proposed. Here, the ...
The DHT11, 21, 22, 33 and 44 are relative inexpensive sensors for measuring temperature and humidity. This library can be used for reading both values from these DHT sensors. The DHT11 only returns ...
Abstract: Optimal sensor and actuator placement is an important unsolved problem in control theory. Nearly every downstream control decision is affected by these sensor and actuator locations, but ...
