Abstract: This paper evaluates the development of a Low-cost security system using small PIR (Pyroelectric Infrared) sensor built around a microcontroller. The low-power PIR detectors take advantage ...
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: 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 ...
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.
While there is a time and place for wirelessly controlled devices, sometimes you want something you can just reach out and ...
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 ...
