Summary
SPI humidity and temperature sensor with configurable averaging, data ready signals, and heater control.
Description
The Sensirion HTS221 component is a capacitive digital humidity and temperature sensor with SPI interface. It features configurable averaging for both humidity and temperature measurements, data ready signaling, integrated heater, and multiple power modes. The sensor provides high accuracy humidity and temperature readings with programmable sample rates and advanced filtering options. Typical applications include environmental monitoring, HVAC systems, weather stations, and industrial process control.
