RE: Snow height measurement system - engolling - 09-04-2019
The first installation of the snow height measurement I see which is not my own
.And in 8 Month and 14 days it is Christmas again so I'm looking forward to get some snow height information of your weather station next season.
Regards

Since winter is near and I finally installed my WeatherDuino outside I noticed that there still is a little bug in the snow height measurement software. When using a holo laser which has no temperature measurement from time to time the value -311,70°C is transmitted as temperature instead of the default -0,1°C.
I think this might be a transmission error of the emulated I2C temperature sensor.
I'm working on it to solve the issue. If somebody wants to help you are always invited to show me my faults ...

Hello,
Today I've done new calibration at a new location of this sensor - so I'm already prepared
to new winter...
(I haven't drawn any graphs yet, I have created it, but I haven't progressed yet. So far, snow height data still only on the web ...)

Just updated the source at GitHub with version 5.
I introduced the possibility to emulate an SHT 3X sensor.
Moreover I fixed the 300 degree celcius stuff with HTU emulation. This was a result of not answering the TX when no valid values were available. Now a value of 0 is sent back.

Hi all,
I have also built up a snow height sensor based on engolling's draft.
As I am not using the WeatherDuino Soft-/Hardware, I use as a base the "Airrohr ESP8266" from the SensorCommunity (luftdaten.info).
The "Airrohr" is originally used as a noise sensor (also named DNMS: digital noise measurement system). I use this noise sensor as well and it supports also to read in an HTU21D - which the engolling snow height sensor is emulating. So the idea to use the "Airrohr" for the snow height sensor was born.
I modified the SensorCommunity software by adding an additional RTC (real time clock) and a SD-card storage.
By default the values are send by the ESP8266 via WiFi to an influxDB. If the WiFi connection is interrupted, the data is stored to the SD-card.
If the WiFi connection is back again, the missed data at the SD-card is automatically resend to the influxDB. This is to add some redundancy.
About the hardware: I have the engolling's pcb completely redesigned and added the RTC, SD-card, ESP8266 sockets and some other minor stuff.
My pcb, the Arduino and the ESP8266 are stacked on each other. Please see some pictures attached.
If you are interested into the pcb, you may send me a PM. I have a few pcb's left from my order.
A special thanks to engolling for his work!

Congratulations! Nice work.

Hi Fuxal,
Welcome to the forum.
Quite interesting work. Thanks for having published it.
Just by curiosity, why have you used two MCU's?

Hi Werk_AG,
well, I used two MCU's, as this was the easiest solution based on existing solutions. Maintenance is certainly easier.
I am not sure how much work it would had been to integrate the snow height sketch into the ESP8266.
