High reliability, high precision and low power consumption temperature and humidity sensor NSHT30

novosense launches CMOS-MEMS-based relative humidity (RH) and temperature sensor NSHT30. NSHT30 integrates a complete sensor system on a single chip, including capacitive relative humidity sensor, COMS temperature sensor and signal processor, and I2C digital communication interface, and adopts 2.5mm×2.5mm×0.9mm DFN and LGA packages. Its I2C interface communication method, extremely small package and low power consumption make NSHT30 more widely integrated into various applications.

From car intelligence to smart home, the system increasingly relies on the judgment of the surrounding environment to make decisions, and uses high-precision sensor products that can respond quickly to capture necessary information, thereby realizing real-time control and autonomous operation in various terminal devices. NanoSemi's high-reliability, high-precision and low-power temperature and humidity sensor NSHT30 can help achieve a more efficient and stable system.

The I2C interface of NSHT30 has two unique and selectable I2C addresses, communication speed up to 1 MHz, and wide supply voltage range from 2.0 V to 5.5 V, making NSHT30 more compatible in various application environments. It also has programmable interrupt thresholds that provide alerts and system wake-up without the need for a microcontroller to constantly monitor the system.
