This library is compatible with all architectures so you should be able to use it on all the Arduino boards.


To use this library, open the Library Manager in the Arduino IDE and install it from there.


The ArduinoHTS221 library allows you to use the HTS221 sensor available on the Arduino® Nano 33 BLE Sense board to read the temperature and the relative humidity of the environment.

To use this library:

#include <Arduino_HTS221.h>

Main features of the HTS221 sensor:

  • Humidity accuracy: ± 3.5% rH, 20 to +80% rH.
  • Humidity range: 0 to 100%.
  • Temperature accuracy: ± 0.5 °C, 15 to +40 °C.
  • Temperature range: -40 to 120° C,
