Hi Zappie,

Thanks for that info.
Where do you found the last one with the plastic cover? I liked it.
Have you already tested the version with 5 meters of cable?

Found it on Aliexpress, my favorit shopping paradise
Here is the link

Still waiting for that sensor, next week it will be there i think. Just asked the seller if he can make e sht31 sensor for me.

Cheers, Zappie

Thank you for the link.
When you get it, let us know how it works. 5 meters its a very long cable for a I2C sensor.

I know, but now i can make ik shorter without breaking the seal. Those sensors are very nice sealed. i had to remove some of it to come at the soldering contacts. The guy from the shop is going to make me a sht31 version.

Cheers, Zappie

Hi!

Werk_AG, here in Ebay you can buy only the plastic case temperature humidity sensor.

Hi,

Yes, we can buy only the plastic case, but to put the sensor inside it, you also need a special pcb adapter, and welding the sensor on it, which is not easy to do at home, because the sensor should be welded using reflow technics.

Hi,
Is SHT71 compatible with SHT1x in WeatherDuino config file ?
Thanks

[laulau]

Yes of course

[werk_ag]

Yes it is. According to Sensirion, the SHT7x family use the same chip than the SHT1x family, differing in the way the module is supplied. The SHT7x have pins.

Hi,
I have some false reading sometime on the SHT71!
Perhaps it's because the Vdd supply should be 3.3V ?
Do you think i can take the 3.3V from the Nano ?

Be aware that the supplied SHT1x library use coefficients for a sensor powered by 5V.
Those coefficients are used to calculi temperature and humidity.

If you are using the bare SHT75 maybe you should use some decoupling caps on the power lines.
