The GY-SHT31-D module integrates the industry-standard Sensirion SHT31 sensor, a CMOSens® chip that combines a capacitive polymer humidity sensor and a band-gap temperature sensor. This digital sensor provides fully calibrated, linearized signals via the I2C bus, eliminating the need for external signal conditioning or complex calibration procedures. The on-chip calibration data ensures measurement accuracy and long-term stability across the specified operating range.
Designed for reliability in diverse environments, the sensor operates from -40°C to +125°C with a fast humidity response time (Ï„63% = 8 seconds). Its low-power architecture makes it suitable for continuous monitoring in energy-sensitive applications, from smart home HVAC control to industrial automation and precision agriculture systems. The module’s straightforward pinout and standard communication protocol facilitate rapid prototyping and system integration.
