I developed an electronic system utilizing an ESP32 microcontroller, integrated with an LED and a motion sensor. The system is designed to function as follows: Motion Detection: When the sensor ...

The circuit diagram for the ESP32 RTC based camera is shown in Fig. 2. Fig. 1: Author’s prototype soldered on board Fig. 2: ESP32 RTC based camera circuit. The circuit is built around voltage ...

The PMW3901 is a small, low-power optical flow sensor that measures movement by analysing surface patterns. It is widely used in robotics, drones, and automation to estimate position changes without ...

The ESP32 chip also produces a web server that can be accessed by any device connected to the same network. The server will load a simple webpage with a message indicating whether or not motion has ...

HC-SR501 PIR Motion Sensor Module Pinout. The HC-SR501 module has three pins. The silkscreen of the module is hidden by the Fresnel lens, so refer to the following pinout given below. Apply power 5V – ...

Smart Bee Designs’ Bee Motion is an ESP32-S2 board with a PIR motion sensor, some GPIOs for expansion, and promising over a year of battery life under the right circumstances. If the name “Bee Motion” ...

An IoT-based motion detection system can be built using the ESP32 microcontroller and the HC-SR501 PIR sensor module. The ESP32 can activate an action, like turning on a light or transmitting a ...
