Engineered for professional-grade environmental sensing, the SHT40 Sensor Probe delivers unparalleled precision in temperature and humidity measurement. Designed with a compact stainless-steel porous housing, this sensor ensures reliable operation in a wide range of harsh and high-pressure environments, including industrial pipelines, HVAC systems, test chambers, and high-humidity zones. With its ultra-low power consumption, 16-bit resolution, and digital I2C output (preset at address 0x44), the SHT40 is a dependable solution for both embedded and industrial applications requiring continuous, long-term stability.

Every unit is individually calibrated and tested, carrying a unique serial number for traceability. The integrated breathable membrane effectively shields internal components from particulates, moisture, and corrosive agents, while allowing accurate airflow for responsive sensing. Enhanced by a variable power heater and full operability in condensing environments, the sensor remains dependable in critical-use cases such as medical devices, automation systems, and explosive zones containing dust or gases.
