  • Max30102,MPU6050 and Esp8266

    I am having some trouble connecting both the MAX30102 and MPU6050 sensors to my ESP8266 board. Both sensors use the I2C communication protocol to interface with the microcontroller.

    I have tried writing some baremetal code to read data from both sensors, but I am not getting any output values from either of them. I have also checked my wiring connections and confirmed that the sensors are receiving power.

    I would really appreciate any suggestions or advice on how to troubleshoot and resolve this issue. Specifically, I would like to know if there are any common issues that arise when using I2C communication with multiple sensors on an ESP8266 board. Additionally, if anyone has successfully interfaced these sensors with an ESP8266 board and can share their code or any tips, it would be greatly appreciated.

    Solution Architecture
    Module Selection: Miniature surface-mount PIR modules (e.g., HC-SR501) with size <20mm×20mm for integration into embedded lighting (ceiling lights, corridor lamps).
    Linkage Logic: Connect to MCUs (e.g., ESP32) via GPIO for "person detected - full brightness; person present - dimmed; person leaves - 30s delay off" control. Integrate light sensors (e.g., BH1750) for daytime auto-shutdown.
    Energy Savings: Reduces lighting energy consumption by 30%-50% compared to traditional switches, ideal for corridors and bathrooms.

    Typical Scenarios Smart Homes: Integrates with Alexa/Mijia systems, allowing APP-adjustable sensing distance and delays. Commercial Lighting: Mall corridors use zoned sensing via RS485 bus for collaborative multi-module control.

    III. Optimization of Sensing Solutions for Security Systems

    Enhanced Intrusion Detection Design Anti-Interference Technology: Dual-element complementary sensors suppress ambient temperature interference; pulse counting (2 consecutive pulses trigger alarm) reduces false positives. Multi-Dimensional Linkage: Combines with microwave radar modules (e.g., HB100) for "infrared + microwave" dual detection, triggering alarms only when both activate to avoid curtain sway or insect interference. Concealed Installation: Modules with integrated lens-housing designs (e.g., RE200B) hide within ceilings or decor for covert security. Data Transmission and Response Wireless Transmission: LoRa modules (e.g., EBYTE E32-433T30D) enable low-power long-range (3km open area) data upload, suitable for villa/factory perimeter security. Rapid Response: <0.5s trigger delay, with local buzzer alerts and cloud notifications (via NB-IoT) within <3s.

    IV. Selection and Deployment Considerations

    Environmental Adaptation Avoid direct exposure to air vents/heating sources. Install at 2.2-2.8m (indoor) or 3-5m (outdoor) height, tilted 15°-30° to cover human activity zones. Outdoor use requires IP65 waterproof modules (e.g., AM312-IP67) with sunshades to minimize solar interference. Cost-Reliability Balance Consumer scenarios: HC-SR501 (~$2/unit); industrial use: Prioritize stability (e.g., Panasonic EKMC1603111, temp drift <±2%/℃). Batch deployment: Reserve 10% redundant modules with self-diagnostic voltage checks for fault
