Description

The GY-SHT35-D module integrates the Sensirion SHT35, a factory-calibrated CMOSens® chip that combines a capacitive polymer humidity sensor and a band-gap temperature sensor. The sensor provides fully calibrated, linearized digital outputs via the I2C interface, eliminating the need for signal conditioning circuits. Its robust design ensures stable performance across a wide measurement range from -40°C to +125°C and 0% to 100% relative humidity.

Engineered for reliability, the module features excellent long-term stability and fast response times. The on-chip memory stores unique calibration coefficients, guaranteeing accurate readings without user intervention. This makes it a dependable component for professional-grade environmental monitoring systems, industrial automation, and data-logging applications where measurement integrity is critical.

Frequently Asked Questions

What is the operating voltage range for the GY-SHT35-D module?

The module operates from 2.4V to 5.5V DC. This wide range allows direct compatibility with both 3.3V systems (like ESP32 or Raspberry Pi) and 5V systems (like standard Arduino boards) without requiring a level shifter.

How do I connect and communicate with this sensor using I2C?

Connect the module's VCC, GND, SDA, and SCL pins to your microcontroller's corresponding I2C bus pins. The SHT35 chip supports standard I2C protocols; you can use libraries like Adafruit_SHT31 (compatible with SHT35) for Arduino or Python packages for Raspberry Pi to read temperature and humidity data easily.

Does the sensor require calibration, and what is its measurement accuracy?

No, the Sensirion SHT35 chip is factory-calibrated, and the calibration coefficients are stored in its on-chip memory. It provides high-accuracy measurements with a typical tolerance of ±0.2°C for temperature and ±2% RH for humidity across its specified range.

Can this sensor be used outdoors or in harsh environments?

While the sensor IC itself is robust, the unwelded module lacks conformal coating or an IP-rated enclosure. For outdoor or harsh environments, it must be housed in a protective, sealed enclosure that prevents direct water ingress and condensation while allowing air exchange for accurate humidity sensing.
