The 7Semi SHT20 Humidity and Temperature Sensor Probe is a high-performance sensing solution designed for environments where precision, stability, and durability are paramount. Equipped with advanced CMOSens technology, this sensor ensures highly accurate and stable humidity and temperature readings across a wide operating range from -40°C to 125°C. Its I2C digital interface supports seamless integration with microcontroller-based systems, allowing efficient data communication with minimal power consumption.

Encased in a stainless steel breathable shell, the metal probe is engineered to withstand high pressures (up to 150 bar), extreme temperatures, and corrosive conditions without compromising sensor functionality. With features like multi-point factory calibration, digital output, and enhanced protection against dust and chemical contaminants, this sensor is ideal for industrial, laboratory, and outdoor applications. The Mini Round Shell connector and 1-meter cable length provide flexible deployment, even in confined or harsh environments such as test chambers, trenches, pipes, and hazardous zones.
