So basically all I need is the following for a complete station, in terms of sensors:
BME280 Temperature Humidity Pressure Sensor
MLX90614 for cloud detection
TSL2591 High Dynamic Range Digital Light Sensor

A Wemos board, I already have an RG11 and I might get the anemometer.


Anybody with a picture of their completed weatherbox?

How is everyone mounting the TSL2591 sensor? (for the SQM part)

Here are a couple of images of my weather station:
  • Wooden housing with acrylic dome for the weather camera and the sensor's box on the left side: 
  • Arduino box with three RJ11 sockets 
  • Raspberry Zero controlling the camera and running the INDI server, having the Arduino attached by USB 
  • Rain sensors testing setup for a RG-11 and a Ventus W174 rain gauge 
Regarding the question how the TSL2591 is mounted: For making it weather proof, I use the plastic foil of a noodle package :-)

nice, any condensation issue in the camera dome?

Inside not at all - I think because of a wooden housing. In the first version I had the humidity sensor inside of the housing with the result, that the humidity was quite stable - due to the buffering effect of the wood.

The only problem that sometimes occurs is that with high humidity and temperature below zero lead to ice on the outside. And from time to time I have to wipe off the dust.

For the SQM sensor, it's important that the foil is very thin - like noodle packages :-). Otherwise, you are measuring the object temperature of the foil and not of the sky. My first tests were with an acrylic dome, but that does not work. Maybe very thin glass like cover glass used in microscopy. I haven't tested it yet since my noodle package works extremely good.

The SQM sensor (TSL2591) does not measure temperature, it's the MLX90614 (infrared thermometer) sensor which measures the sky temperature.

If you compare the SQM reads from the TSL2591 and an official Unihedron device, TSL2591 read's are not stable.
TSL2591 is good just to have a value of SQM, but it is not the real value, just an estimation

Hi. I build a weather based on ESP8266, BME280 and MLX60914. But I have problem how to set correction factor K1-K5. Default one result in totally inadequate results. Like half covered sky result from -20 to -15C while ambient temperature is around 0C. What coefficients do you use in colder climate?

An observation, in your live weather station at weather.openfuture.de/

The following link weather.openfuture.de/weatherradio.html shows "Last update: 12/03/2021, 09:34:01"
while the following link weather.openfuture.de/sensordata.html does not show it.
I think it should be there too for consistency :) 

Also it might be a good idea to include the satellite image like we have in the original meteostation code.

How do you get the I2C to work with the MLX90614???
I am not getting any data at all, Arduino serial console:

Weather Radio V 1.12
{
  "MLX90614": {
    "init": false
  }
}

i even loaded up a simple script to check and no go, what's the trick please?

If you have the discrete version of the MLX90614 (not mounted on a board), as there is a 3.3 volt and a 5 volt version, you may not be operating it at the appropriate voltage.

The hard to read markings on the side should be MLX90614ESF-BAA-000-TU for the 3.3 volts part and MLX90614ESF-AAA-000-TU for the 5 volts one, or something similar (BAA - 3.3V, AAA - 5V).

cool thanks, I shall look into the marking, the sensor is mounted on a little board.
