Building Guide - Enhanced Sensor Platform

Required Materials & Tools

Electronic Components:

• Wemos D1 Mini ESP8266 microcontroller
• BMP280 barometric pressure sensor
• VEML6075 UV index sensor module
• MQ-135 air quality sensor module
• DHT11 temperature and humidity sensor
• DS3231 real-time clock module
• 10kΩ pull-up resistor

Assembly Tools:

• Soldering iron (temperature-controlled preferred, 350°C/650°F)
• 60/40 rosin-core solder
• Soldering flux for improved joint quality
• Desoldering wick or solder sucker for corrections
• Brass sponge or steel wool for tip cleaning
• Heat-resistant soldering mat or surface
• Precision tweezers or small needle-nose pliers
• Magnifying glass or microscope for inspection
• Isopropyl alcohol (99% preferred)
• Lint-free cleaning cloths
• Masking tape or Blu-Tack for component positioning

Assembly Process

1. Workspace Preparation Set up a clean, well-lit workspace with adequate ventilation. Ensure your soldering iron station is stable and the tip is clean and properly tinned.

2. PCB Preparation
Thoroughly clean the PCB with isopropyl alcohol and a lint-free cloth to remove manufacturing residues, oils, and contaminants that could affect solder adhesion.

3. Component Inspection Carefully examine each sensor module and verify that all header pins are straight and undamaged. Gently straighten any bent pins using needle-nose pliers.

4. Header Pin Installation Insert the appropriate header pins into each sensor module, ensuring proper alignment. The pins should sit flush and perpendicular to the module surface.

5. Component Positioning Place each component on the PCB according to the silk-screen markings, ensuring proper orientation (especially for polarized components). Use masking tape or small amounts of Blu-Tack to secure components during soldering.

6. Soldering Process

• Heat your soldering iron to the appropriate temperature (350°C for 60/40 solder)
• Tin the iron tip with a small amount of fresh solder
• For each joint: Heat the pad and component lead simultaneously, then feed solder into the joint
• Remove solder first, then the iron, allowing the joint to cool undisturbed
• Each joint should appear shiny and form a proper fillet shape

7. Quality Inspection Using a magnifying glass, inspect every solder joint for:

• Cold solder joints (dull, grainy appearance)
• Solder bridges between adjacent pads
• Insufficient solder coverage
• Component misalignment

8. Corrections & Cleanup Address any soldering defects using desoldering wick or a solder sucker. Clean the entire PCB with isopropyl alcohol to remove flux residues.

9. Initial Testing Before programming, perform a visual inspection and continuity testing to ensure all connections are proper and no shorts exist.

10. Programming & Configuration Upload the provided Arduino code using the Arduino IDE. The enhanced code includes:

• Automatic sensor initialization and error handling
• WiFi access point creation with user-friendly network name
• Complete web server with modern dashboard interface
• Real-time data API for integration possibilities
• Comprehensive serial monitor output for debugging
