Temp probe with SHT35
« on: April 23, 2020, 10:22:26 AM »
Exciting news...
Ecowitt have a temperature sensor in dev/test with a SHT35 on board

I am just so impressed with the company and team, they so listen to their customers!

What are the differences or advantages to the currently available sensors?

I hope that they lower the humidity range that is currently limited to minimum 10% RH.

This needs to go into the outdoor WH32 so that we can upgrade current stations. Maybe it should be called the WH35 (I don't think that exists).

Lucy, advises that this is close to being available, so we will soon see.
I imagine the benefits will be the sensor precision

I can confirm, the idea was started from my personal push to ecowitt, supported by our italian community, due to would like to have a better sensor, a lower probe dimension and to obtain the best performances using this sensor in high quality solar radiation shields, like Barani Meteoshield Pro that require a low dimension probe to obtain the best internal airflow

the first prototype, tested by ourselves, was made by an our top user, Raffaello, sometimes present in this forum

if you want I can post an image of probably definitive sensor

Okay, but does it have the 10% humidity limit removed?

il prezzo è accettabile , la qualità costa , ci sono sensori che costano lo stesso e non sono nemmeno degni di essere presi in considerazione  ;)

I can officially confirm that the new Wh31/32 sensor with external sht35 probe will not have the humidity lower limit at 10%

Yesterday a good day to test the performance of the sht35 external probe inside meteoshield pro vs the wh31 standard sensor inside another meteodhield pro

Same difference as WH31 and WH32.

The WH31 is the optional sensor model where you can select up to 8 channels, allowing you to have 8 extra optional sensors.
The WH32 is the given main and only outdoor sensor for the station and also serves as an outdoor override for the WH65 or WS80.

Any update on when the new sensors will be available? 

I want to get a new Ecowitt station, but I want to wait until I can get it with the new sensors.

If you can't wait, the sensor alone is available on Amazon

Sensor alone doesn't do me much good though.
I guess it could be a lovely tie tac...

very strange, I have talked today with ecowitt and he send me the new sensor image
I know that they need about 4 weeks to prepare and ship, so I'm confused   #-o

I believe there are online instructions to connect it to the WS-2902 or WH32

Maybe that's what she meant

As for the new outdoor sensor, sorry that you may still need to wait for several weeks.
We'll let you know when it's available.
