Sensors Humidity Temperature i2c DO NOT go wrong

There are several close references and even some sellers mix the brushes.

This little tutorial is a feedback from my orders and tests (which made me waste a lot of time).

I have always needed Sensors Humidity/Temperature (and incidentally atmospheric pressure).

If you buy a sensor for less than €2, it will not give you moisture, the correct price is between €6 and €8.

Wrong reference

Do not order the reference HW-611 E/P 280

611

Wrong reference

Do not order the reference GY-BM ME/PM 280

This reference only gives the temperature.

Good reference

Order: GY-BM E/P 280

Or

280

On the back of the circuit, a small clue

Advice

  • If the seller does not show you the reference by showing you only the front, avoid!
  • Do not buy this product for example or this one, they will not give moisture.
