7Semi SHT40 Humidity and Temperature Sensor Probe, ±1.8 %RH, 14mm dia., 93mm length - I2C Interface
The 7Semi SHT40 is a high-precision digital humidity and temperature sensor probe designed for demanding industrial and embedded applications. Featuring a robust stainless-steel porous housing and an I2C interface (address 0x44), it provides reliable 16-bit measurements from -40°C to 125°C and 0-100% RH, compatible with 3.3V systems like Raspberry Pi, ESP32, and STM32 microcontrollers.
Features
- High-precision digital sensing with ±1.8% RH and ±0.2°C typical accuracy.
- Robust stainless-steel porous probe housing rated for pressures up to 150 bar.
- Ultra-low power consumption (~80 nA idle) ideal for battery-powered systems.
- Integrated heater for enhanced accuracy in condensing or rapidly changing environments.
- Simple I2C interface (address 0x44) for easy integration with microcontrollers and SBCs.

The 7Semi SHT40 probe utilizes a capacitive polymer sensing element for humidity and a band-gap sensor for temperature, delivering calibrated 16-bit digital output via a standard I2C bus. Its stainless-steel porous filter protects the sensing core from dust, moisture, and corrosive contaminants, ensuring long-term stability in harsh industrial environments such as HVAC ducts, process control, and outdoor monitoring stations.
Engineered for reliability, the sensor includes an on-chip heater that can be activated to clear condensation or perform diagnostics. Operating from a 1.08V to 3.6V supply, it is perfectly suited for low-voltage embedded systems and portable data loggers where power efficiency and measurement integrity are critical.
