This project demonstrates how to use an ESP32 to control an LED based on readings from a light sensor and a motion sensor. The LED will turn on when there is no light and motion is detected, and turn ...

Signal Pin (Out): Connect to GPIO 2 on the ESP32 (LDRPIN) VCC: Connect to 3.3V on the ESP32 GND: Connect to GND on the ESP32 IR Obstacle Sensor (Digital) Signal Pin (Out): Connect to GPIO 34 on the ...

Carrying that forward, in this project the ESP32 cam attached with RTC can take pictures based on time and save them on an SD card attached to the board. The design can be further developed to capture ...

This breadboard compatible package combines an ESP32-S2 module with a top-mounted PIR sensor, making it a turn key solution for all sorts of motion sensing projects.

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 code for the HC-SR501 is very simple and on top of that it does not require any library to work with. As we all know, the pin of the PIR sensor goes low when motion is detected by the PIR sensor.

As I've experimented and played with a lot of different sensors, I've discovered that these basic devices can be built for ...

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” ...

The ESP32 microcontroller with the HC-SR501 PIR sensor module can be used to create an IoT-based motion detection system. Using its built-in A/D converter, the ESP32 may take action based on the ...

Bright Bulb seems like a simple copy of a color changing LED bulb, but features a nice custom board for the ESP32 and neopixel LED and an ESP-NOW networked remote ambient light & motion sensor.
