Description
The Sensirion SHT45 temperature and humidity sensor is one of the most accurate and advanced measurement solutions available on the market. Based on the fourth-generation SHT sensor, it delivers exceptional precision: ±1.0% RH in the 25% to 75% humidity range and ±0.1°C in the 0 to 75°C temperature range. Unlike older models, the SHT45 communicates via a full I2C interface, simplifying integration with most microcontrollers and single-board computers. The breakout board includes a built-in voltage regulator and logic level shifter, allowing it to operate with 3.3V to 5V systems. Thanks to the STEMMA QT connectors (Qwiic compatible), the sensor can be quickly connected without soldering – just use a QT cable (sold separately). Additionally, each kit includes a fully assembled PCB and a header strip for optional soldering – perfect for breadboard use. An integrated PTFE membrane offers extra protection against dust, liquids, and particles, achieving IP67-rated sealing, making it suitable even for harsh environments. The sensor is tested according to JEDEC JESD47, comes with a calibration certificate compliant with ISO 17025:2017, and supports heater power and full NIST traceability. It’s an excellent choice for precision measurement applications, IoT projects, weather stations, or home automation systems.
