Description
KAmodHTS221 is a module, which allow to make a measurement of humidity and temperature. Thanks to embedded voltage regulator and logic level translator, it can be used in embedded system with power supply 2.5 - 5.5V. Module KAmodHTS221 bases on humidity / temperature sensor HTS221 from STMicroelectronics. The characteristic features of this sensor are: measurement possibility in range 0 - 60°C or air humidity in range 0 - 100%.
