Room Weather Station Using Arduino and BME280 Sensor

Room Weather Station Using Arduino and BME280 Sensor

We have built quite a number of weather stations in several past tutorials, with each one differing from the other by the use of a different sensor, different display, etc. Today, we are going to build another weather monitoring station using the BME280 Temp and humidity sensor from...

Using ESP32’s Flash Memory for data storage

Using ESP32’s Flash Memory for data storage

The ESP32 has about 4MB of internal flash memory and since the data stored within the flash memory is retained even when power is recycled, it becomes super useful for applications where you need to keep certain amount of data even after power off. For today's tutorial, we will learn how...
