BME 680 Sensor connected to WIfi through an ESP8266, uploading to Google Sheets on Google Drive, and then shown on a Google site. A ESP32 would work just as well as the extra ESP8266 features are not needed. The BME 680 sensor advertises temperature, humidity, air pressure, gas, and rough altitude.

I do lived near sea level, however the altimeter is based on air pressure, and thus it looks like as the pressure goes up, my house is sinking.

Altimeter might work well in a car. Plug it into a car usb port and upload through a cell phone hotspot. Maybe add on a GPS chip.
