PIR Motion Sensor Working! Now Debugging the BH1750 Light Sensor

 

I’ve been working on a project that combines a PIR motion sensor and a BH1750 light sensor to create an automatic lighting system. After troubleshooting, I successfully got the PIR motion sensor working, but I’m still working on fully configuring the BH1750 light sensor.




The PIR motion sensor detects movement and adjusts the LED brightness accordingly. When motion is detected, the LED brightness increases, and when no motion is present, it dims.



 My Serial Monitor confirms this, displaying messages like "Motion Detected! Increasing brightness..." and "No Motion. Dimming lights...". This means the PIR sensor is responding correctly.


However, the BH1750 light sensor is still giving me issues. The Serial Monitor keeps showing "[BH1750] Device is not configured!", which means the sensor isn’t initializing properly. 



Once the BH1750 is fully functional, my project will be able to dynamically adjust light brightness based on both motion and ambient light levels, making it more efficient and responsive. With the PIR motion sensor working.

1. light intensity based on room occupancy Simulation

Image
This project is a smart lighting system that automatically adjusts light intensity based on room occupancy using a PIR motion sensor. When someone enters the room, the lights gradually brighten, and when the room is empty, the lights dim down smoothly or turn OFF. The system can also use a relay module to control high-power bulbs. I used WokWI to simulate this and also provided the code for it as well and a link of the simulation at the bottom.   Code: #define PIR_SENSOR 2  // PIR Sensor connected to Digital Pin 2 #define LED_PIN 9     // PWM LED pin #define RELAY_PIN 8   // Relay pin for full light ON/OFF   int brightness = 0;  // Initial LED brightness bool motionDetected = false;   void setup() {     pinMode(PIR_SENSOR, INPUT);     pinMode(LED_PIN, OUTPUT);     pinMode(RELAY_PIN, OUTPUT);     Serial .begin(9600); }   void loop() {     int motion = digital...

Proposal - vision based smart lighting

  PDE3823 – Project Proposal   Student Name: Abdi Ali Student Number: M00814431 Topic of Study: Vision-based smart lighting Assigned Supervisor: Mr. Huan Nguyen   Working Title Development of a Smart Lighting System Using Room Occupancy, Natural Light, and Gesture Based Control   Problem Definition Modern energy efficiency solutions require intelligent systems to optimize power usage. Traditional lighting systems lack adaptability, leading to wasted energy in unoccupied rooms or areas with ample natural light. How can an intelligent lighting system, integrating computer vision, sensors, and gesture-based control, improve energy efficiency while enhancing user convenience?   Justification and Context The demand for energy efficient solutions has surged due to global energy concerns and environmental policies. Smart lighting systems address these challenges by reducing unnecessary energy consumption. Combining automation, gesture control, ...
