![]() You can cram everything into a plastic enclosure, but make sure to use electrical tape or screw in the various components so they don't cause interference or come unplugged. The Pi 3 has a tendency to run warm depending on the enclosure you are using you can check temp with /opt/vc/bin/vcgencmd measure_temp and may add a heatsink and/or fan as necessary. Log file size for temperature, humidity, ratio and concentration is about 15K for 45 hours, so around 8K written per day. So it would take about 125 days to write 1MB of data.įor easy visualization of the data, Google Sheets with a chart can be configured. Instructions such as the Adafruit ones here can be followed to set up the Pi to write directly to a Google Sheet which has a live-updated interactive chart that is publicly accessible. ![]() An example of a Google line chart created with the output data file. If the Pi does not have network access, you can simply copy the data via USB and open the tab-delimited file into a Google Sheet as needed.Īs the Pi gives off heat, the temp sensor seems to be most accurate when placed a few inches from the enclosure, as shown in the picture above.This application logs weather data - temperature, barometric pressure, and relative humidity data from sensors connected to a Raspberry Pi. The weather data for each day is periodically and continuously logged into a local SQLite3 database, restarting on every (re)boot. #Raspberry pi temperature and light logger update.#Raspberry pi temperature and light logger install.
