How accuarate are the sensors in the Nano 33 BLE Sense supposed to be? For instance the HTS221 sensor on my board delivers a temperature that is about 7°C too high and a humidity of about 11% too low. Obviously it is simple to correct these values but is this usual behaviour for this sensor?
If the temperature is wrong then the humidity calculation will also be out .
Some idea of how you’ve mounted the device , power supply and code would help .
The Nano 33 BLE sense is simply mounted on a breadboard for stability with only a USB cable connecting it to my laptop. I am running the example sketch "ReadSensors". I have tried the setup against a battery LED Thermometer outside and in several rooms in my house, including the cellar.
It looks like you are not alone , there are other threads on this, can’t help with a solution tho .
Data sheet for the sensor gives +- 0.5C so I too don’t understand why it’s so far off - unless it’s next to something hot on the PCB. I can’t believe Arduino would let something like that out ?? -you do have a genuine board btw ?? A clone could be miles off and I wouldn’t be surprised.
Data sheet
Yes, I have a genuine Arduino Nano 33 BLE board., bought from the Arduino Store. I also bought an Arduino R4 Wifi from the same source, but it had no Bluetooth functionality and very limited Wifi functionaliy until I uploaded the firmware 0.2.0 which destroyed the LED Matrix Library.
As a long time genuine Arduino user I must say that there does seem to be huge problems with the latest products.
There are reports of the RTC on the UNO R4 being inaccurate too , not tested mine yet - there is a thread on it on the R4 section .
It does seem like Arduino Co. is rushing out unfinished products that are not particularly well thought out, nor thoroughly tested. Caveat emptor!
