North Turramurra Weather Site

Introduction

This site has information about, and readings from, my automatic weather station based in North Turramurra, New South Wales, Australia, which is about 20km north of Sydney. In April 2020 it was relocated 3km south east from North Wahroonga. For more information about it, see below. For the readings, click on the links. The weather station has been active since November 2014. I previously ran a weather station in Colchester, Essex, UK, prior to moving to Sydney.

The Weather Station

The weather station is an Ecowitt/ Pantech HP2550 Weather Station. Click here to see more details. The location is in North Turramurra, near Sydney, Australia: 33 43' South, 151 9' East, 150m above sea level. There is an integrated solar powered sensor suite which communicates to the base station by radio link. The base unit connects by WiFi to a router and uploads to the Weather Underground website. I have routines to also update this website with the data and analysis.

The main display unit for the weather station receives the sensors wirelessly and connects via WiFi to a router and uploads data to Weather Underground.

This is the integrated sensor suite. This records outdoor temperature, humidity, rainfall, brightness, UV level, wind speed, wind gust speed and wind direction. There is also an indoor sensor which records temperature, humidity and barometric pressure.

Station Records/ Climate Statistics

I have carried out analysis of the weather recorded for the period January 2015 - December 2023. The analysis can be accessed here.

Calculation of Sunshine Time

The weather station measures brightness but does not calculate sunshine duration. I have developed code using the algorithms known as the "Carpentras Method" and the data uploaded to Weather Underground to calculate the sunshine duration for each day. This gives a good match to the calculation the WsWin software makes. The equations and code are available for use and can be accessed if you click here.

Air Quality Monitoring

In January 2018, I added an air quality monitoring sensor. This uses the Plantower PMS5003 sensor and I have used a Raspberry Pi to capture the data. The software is based on that produced by https://www.rigacci.org but I have altered it to provide the outputs displayed on this website. 

In January 2020, I added a carbon monoxide monitor using the Winsen ZE-07CO sensor. This gives a high resolution reading as a serial output. I have developed software for the Raspberry Pi to read and record this and upload it to my website.

Further information about air quality can be found here.
