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 ...

In this video I'm building an Arduino Heart Rate Monitor that is housed in a toy handle in the style of the Star Trek Tricoder. The device uses the PulseSensor with an Arduino Pro Mini and an OLED ...

Methane emissions from wetlands are rising faster than those from industrial sources, prompting concerns about a climate feedback loop. Methane emissions from wetlands are rising faster than those ...

Abstract: This paper presents, for the first time, the monolithic integration of a microcantilever gas sensor with CMOS circuits. The microcantilever-based microplate and optimized gas-sensitive ...

Abstract: Following this paper, the design, implementation, and evaluation of an intelligent optical gas leakage detection system based on machine learning and an Arduino platform to enhance the ...

This program written with Arduino Code running on ESP8266 (Wemos D1) is just a test to access, read status and control Tuya compatible WiFi Smart Devices (Plugs, Switches, Lights, Window Covers, etc.) ...

Here we are designing a very small, tiny CAN network sensor that can be attached to any vehicle. It detects motion, accidents, and all vehicle activities in real time. It can also be modified to act ...

This code implements a steady-state drift-flux model for simulating multiphase (liquid and gas) flow in wells. Three-phase flow (gas, oil, water) is supported by treating the oil and water as one ...
