Last week we connected a ICStation BME280 temperature / humidity / barometric pressure sensor to a a ICStation NodeMCU ESP8266. We displayed the collected data (along with Dew Point and Heat Index calculations in the serial monitor.
This week we modified the sketch to post those variables to a linux server (could be your own local Raspberry Pi) running MySQL and PHP. We have it set to take a reading every 30 seconds, and post the data to a php page that inserts the data into the MySQL database. The index page displays a table of that data. The time and date stamp has been modified to display the data in the timezone of the location of the sensor. We are working on live gauges and graphs to display this data in real time.”
