Household Smoke Detector

Overview

The EU070 Household Smoke Detector (EU070-SMOKEDETPOCZ EVM Board) is a photoelectric-based detection system designed for accurate and efficient smoke monitoring. Using an infrared photodiode and phototransistor housed in a specially designed chamber, the system ensures reliable detection of smoke particles while minimizing interference from external light.

Powered by Renesas’ RAA239101 low-power analog front-end IC and the RL78/G12 MCU, this smoke detector provides timely alerts through visual (LED) and auditory signals, ensuring maximum safety in household applications.

Capabilities

  • Normal Conditions:
    • GREEN LED ON, RED LED OFF, indicating no smoke detected.
  • Smoke Contamination:
    • RED LED blinks when smoke is present, confirming successful detection. GREEN LED stays ON.
  • System Status:
    • GREEN LED remains ON at all times to show power and functionality.

Features

  • 10-Second Smoke Detection Intervals:
    Continuous monitoring with rapid 10-second checks for prompt smoke detection.
  • Visual Smoke Indication:
    Red LED blinks to signal smoke detection, offering clear visual alerts.
  • Flexible Power Options:
    Supports both DC and AC power sources for versatile installation environments.

 

The EU070 Household Smoke Detector combines precise smoke detection with flexible installation options, making it a reliable choice for enhancing home safety. Explore its features and performance in the evaluation lab to experience the cutting-edge capabilities of Renesas technology.
