DL-THS10B-SHT40 Next-Gen Digital Temperature & Humidity Sensor Module (I2C Industrial Probe)
The DL-THS10B-SHT40 is an industrial-grade, ultra-high-precision digital temperature and humidity transmitter designed for elite climate monitoring under demanding conditions. This module features a massive generation leap, leveraging Sensirion’s 4th-generation SHT40 sensor IC to deliver industry-leading accuracy, drastically reduced power consumption, and enhanced resilience against environmental stress.
Housed in a ruggedized, highly ventilated DL-THS10B industrial casing, it keeps the high-performance silicon core safe from dust and physical debris while allowing instant, unrestricted airflow for real-time tracking. Operating over a native I2C communication interface, this module is a plug-and-play choice for engineers and developers working with Arduino, ESP32, STM32, and Raspberry Pi systems.
Key Features & Product Upgrades
- 4th-Generation Sensirion Core: Features the newest SHT40 chip, which offers superior reliability, enhanced dust protection, and significantly faster response times compared to older SHT30/SHT31 models.
- Extended -40°C to +125°C Range: Built with advanced, high-durability internal materials and specialized wiring insulation, allowing the fully assembled module to be deployed safely across extreme thermal boundaries.
- On-Chip Power Heater: The SHT40 core features an integrated software-controllable internal heater. This allows the sensor to actively clear dew formation and condensation, preventing long-term sensor drift in high-humidity or freezing conditions.
- Premium +/-1.8% RH Accuracy: Delivers tight relative humidity tracking +/-1.8\% RH (typical) and crisp temperature calibration +/-0.2 C (typical) right out of the box.
- Ultra-Low Power Consumption: Optimized for wireless remote nodes, battery-powered IoT applications, and green energy control circuits.

Wiring & Pinout Guide
Integrating this sensor into your host controller board is simple via standard 4-wire I2C lines:
- VCC: Power Input (Typically 3.3V)
- GND: Ground Reference
- SCL: I2C Serial Clock Line (Requires pull-up resistor if not integrated on the microcontroller board)
- SDA: I2C Serial Data Line (Requires pull-up resistor if not integrated on the microcontroller board)
Why Choose the DL-THS10B-SHT40 over the SHT30?
While the SHT30 is excellent for everyday indoor applications, the DL-THS10B-SHT40 is the definitive choice for applications where failure is not an option. Thanks to its broader -40°C to +125°C limits, tighter humidity tolerances, and the ability to cook off condensation using its internal heater, it provides the ultimate field reliability for your commercial layouts and industrial control panels.
