Compact Housing for Smart Sensor System

This housing is specifically designed for the HC-SR501 motion sensor, paired with a DHT11 temperature and humidity sensor, an LDR light sensor, and the ESP8266 Wemos D1 Mini. It offers an elegant and space-saving solution, ideal for use with ESPHome and Home Assistant.

Design and Functionality

• Precise Openings: Perfectly aligned for the motion sensor and other components, ensuring optimal performance.
• Ventilation Slots: Enable accurate temperature and humidity measurement for the DHT11 sensor.
• Compact Size: Fits seamlessly into various environments, whether on a smart-home shelf or mounted on a wall.
• Modular Design: Easy to open and flexible for future upgrades or component replacements.

Materials List

Electronics

• ESP8266 Wemos D1 Mini: Microcontroller for integration with ESPHome and Home Assistant.
• HC-SR501 Motion Sensor: Detects movement within the vicinity.
• DHT11 Temperature and Humidity Sensor: Measures environmental temperature and humidity.
• LDR (Light Dependent Resistor): Measures ambient light levels.
• Resistors:
  • 5 kΩ pull-up resistor between VCC and DATA (for the DHT11).
  • 10 kΩ resistor between the LDR and Ground.
• Jumper Wires: To connect components together.
• Micro-USB Power Supply: To power the ESP8266 module.

Enclosure and Accessories

• 3D-Printed Housing:
  • Optionally print the Wemos_D1_BWM_case model in Fuzzy Skin Mode for a unique texture.
  • Note: There is also a Wemos_D1_BWM_lid_V1 available as an alternative lid design.

• Screws: to mount the cover plate.

   

Tools

• Soldering Station (or breadboard for prototyping).
