All, up to now i have been using sht21 temp & humidity sensors on small breakout boards for projects. I like their accuracy, i2c bus interface and 3.3V compatibility.
I was looking for something more robust for an outdoor sensor and found these on eBay. They mention Arduino and sht21 compatibility. But i know enough to distrust eBay descriptions. Its not that i think the sellers are dishonest, just that they are not experts in what they sell.
I realise it will be important to place them in a shaded & sheltered position.
Any thought or experiences please?
