Logging Weather Data with an Arduino Microcontroller

CORRECTION: At minute 6:50, I should have stated "1 minute", not "1 second".

This video summarizes multiple tests and lessons learned in using various microcontroller configurations to log weather data to an SD camera card. It summarizes the collection of 230K+ records collected by five different microcontroller-datalogger-RTC combinations using various sensors for monitoring atmospheric conditions during the summer monsoon in Tucson, Arizona (2022).

Respective tests include the use Arduino-based data-logging shields coupled with Bosch and DHT22 weather sensors for temperature, humidity, pressure, and elevation.

Good video! the height is derived from the air pressure and is changing of course according to the weather conditions and changing air pressure. A reference sensor with an exactly know topographic height could help in case you need a high accuracy. By comparing two BME280 humidity sensors I also made the experience, that can they easily differ by 10%. Reasons can be a slightly different mounting with different air convection. I am using the sensor together with LoRa boards and I gathering the data with a LoRa receiver and a little webserver.

This was really cool! I just deployed a bunch of data loggers based on the Beaglebone Black out to several industrial agricultural sites. We have mains power and LTE access so we are able to upload data real time to Amazon Timestream as well as writing to local disk (just in case). It's really cool seeing what others are doing with their field deployments.

Thanks for digging into the altitude question in the BME280 library. I was wondering about the internal workings of that particular issue when I was using the BME680 in my home weather station.

Nice review. Humidity measurenment is "expensive". Cheap sensors, like DHT11 or DHT22 does not work well. I use Texas Instrument sensors, like HDC2080, Sensirion sensors, SHT1X, SHT2X or SHT3X, and Bosch sensors, like BME280. Regarding the RTC, I only use DS3231, only because I've bought a bunch. In a couple of applications I've synced the time using a GPS module in a location without cellphone signal, and a SIM800L module in a diferent location with a good cellphone signal. It is more expensive, but I really needed the exact time.

I Need ur help
iam poor in english pls adjust the comment
..accidently i gave 12v in my arduino uno rx pin then my arduino uno not working and the usb to serial ic chip heating and my arduino on but iam press reset button its not reset and the led not working i hope my arduino not died the usb to serial ic was died so now iam totally blank what can do next i don't know and iam not have money to buy other uno so i need ur help

hope u reply the comment 🤧
