Abstract: This research paper presents an automated monitoring system developed with diverse technologies combining cloud computing and Internet of Things (IoT). The system includes motion sensing, ...

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.

This is a maintained version of the original DFRobot_mmWave_Radar library. After more than two years had passed without any commits beyond the initial commit, and issues receiving no attention, I ...

In this video, I'm exploring the use of Mini PIR Sensors with ESP32 with both Arduino-based projects as well as making a movement sensor for Home Assistant by using ESPHome. The sensor is quite ...

An Arduino library for the Hi-Link HLK-LD2450 24Ghz FMCW radar sensor. This sensor is a Frequency Modulated Continuous Wave radar, which makes it good for presence detection and has some interesting ...

For some, Halloween is starting to rival Christmas for setting up elaborate holiday decorations. Homeowners now spend many hours─and sometimes dollars─creating ghoulish displays of lit pumpkins, ...

I’ve just come across a no-name non-contact, high-precision 80 GHz mmWave radar sensor for liquid level detection with a 40m range, ±5mm accuracy, and Modbus communication over UART. The 0.15m to 40m ...

This IoT Fall Detection System provides a proactive solution, ideal for those seeking to enhance the safety of loved ones or individuals at risk of falls. Falls pose a serious risk, particularly for ...

We may receive a commission on purchases made from links. Since it would be challenging to find all the different types of sensors in one place, we decided to put together a list of some of the best ...
