Hi kgoveas, Thanks for the reply. My application requires to measure the height of the product placed in a warehouse(to track or locate products in warehouse) which means over a period of time(for example, If I place the sensor at 930meters from sea level for 3 days or more) it should show the same height in order to track it but with current scenario, the height is changing over a period of time even though we place the sensor at the constant position. Using pressure and temperature data we are able to calculate the height but the issue was as you said it will be varied depending on the time of day and the weather itself. So, We can't get the constant height if we place the sensor in the same position over a period of time? Is this sensor serves for my application? or Can you suggest any other sensor which will work for my application?

Hi, My application requires measuring the altitude with 0.5m to 1m accuracy. So, I am using the BMP280 sensor to calculate the altitude. The sensor is connected to the NODEMCU(ESP8266) and data read using the I2C interface in Arduino IDE. But while testing the altitude varies to 20m even though the sensor is kept at someplace over a period of time(around 6hrs). PFA for the code and image which shows the variation in altitude (MIN and MAX). Please suggest some solution in order to get the required functionality.
