ENS21x Family – High Performance Digital Temperature & Humidity Sensors
The ENS21x is a family of high-performance temperature and relative humidity sensors with accuracies suited to certain applications.
The ENS21x series offers industry-leading accuracy, with readings as low as 0.1°C for temperature and 0.8% for relative humidity. Fast response time and dependable long-term functionality make it appropriate for many applications. This includes cold chain management, household appliances, building and automotive HVAC, industrial automation and instrumentation.
The devices are housed in a small QFN4 package and have an I²C interface for interacting with a host CPU outside of it. Additionally, the ENS21x series integrates seamlessly with ScioSense’s gas sensor portfolio and offers digital, pre-calibrated outputs (Kelvin and relative humidity percentage).
