BME280-Temp-Sensor

CM BME280 Temp Sensor Demo (BME280-Temp-Sensor)

This example shows a simple temperature/humidity/pressure setup based on a BME280 sensor and the ConfigurationsManager Web UI.

What it demonstrates

• Core settings templates: WiFi + System + NTP via cm::CoreSettings
• Settings-driven WiFi startup via ConfigManager.startWebServer() (DHCP/static/AP fallback)
• WiFi lifecycle hooks via cm::CoreWiFiServices (OTA init + NTP sync ticker)
• Runtime provider + Runtime meta for live sensor values in the Web UI
• Periodic sensor reads via Ticker

Hardware

• ESP32 (e.g. NodeMCU-32S)
• BME280 (I2C)

Default pins (see src/main.cpp):

• SDA: GPIO21
• SCL: GPIO22

How to run

From the repo root:

pio run -d examples/BME280-Temp-Sensor -e usb
pio run -d examples/BME280-Temp-Sensor -e usb -t upload

First start / AP mode

If no SSID is configured yet, the device starts in AP mode. Open the printed AP URL from Serial (usually http://192.168.4.1) and configure WiFi via the Web UI.
