Graphical presentation of Sensordata with ESP8266

In an earlier post I described the use of a graph, showing results of a BME280 and DS18B20 sensor. This was based on an article from siblings Rui anĸ Sara Santos from randomnerdtutorials, but tailored to my needs. The biggest difference with the original article is that i used a JSON for data transfer in … Continue reading “Graphical presentation of Sensordata with ESP8266”

Graphical and Table presentation of database info using Googlecharts and PHP

In an earlier post I discussed storing sensor data in a MySQL or MariaDB database (in combo with DeepSleep, which was the focus of the article).The database part was based on an article by randomnerdtutorials.Output of the gathered MySQL data was in shape of a table*). Sometimes though a graph is a more practical way … Continue reading “Graphical and Table presentation of database info using Googlecharts and PHP”

Storing Arduino sensor data on a (local) server using POST or GET and PHP and presenting it in a graph

In an earlier article, I described how to store your sensor data in GoogleSheet I also described how to make graphical presentations of data with the Highcharts library (much based on an article of Sarah&Rui Santos of Randomnerdstutorials, but extended by me). That method was especially suited for an ESP8266 or ESP32 as they can … Continue reading “Storing Arduino sensor data on a (local) server using POST or GET and PHP and presenting it in a graph”

Showing ESP8266 battery voltage in a graph

In a previous post, I dabbled around with presenting sensor readings with the Highcharts graphic library, based on a post on the randomnerdtutorials website. It might be educational to add another channel to it that reads battery voltage and presents that in a graph as well. In the picture above there are two colours: when … Continue reading “Showing ESP8266 battery voltage in a graph”

ESP8266 Plot Sensor Readings in Real Time Charts on a Web Server

Until recent, I had not bothered much about adding graphics to my ESP8266 programs, as I was using Openhab and Influx/Grafana for graphical presentation of data. In fact I never fully realized what was possible on an ESP8266. Then I saw some great graphics for a BME280 on the randomnerdtutorials site from Rui and Sara … Continue reading “ESP8266 Plot Sensor Readings in Real Time Charts on a Web Server”
