The SHT35 sensor module is a high-precision temperature and humidity sensor. Offering improved accuracy and stability, it works through a simple I²C interface and supports a wide operating voltage of 2.4–5.5 V. Suitable for professional climate monitoring, indoor air quality systems, and industrial IoT solutions.
Features- Humidity Range: 0–100 %RH
- Accuracy: ±1.5 %RH / ±0.2 °C
- Temperature Range: -40 °C ~ +125 °C
- Interface: I²C digital output
- Operating Voltage: 2.4–5.5 VDC
- Dimensions: 17 × 12 mm with 4-pin header (VCC, GND, SDA, SCL)
- High Accuracy: Improved stability and repeatability
- Applications: Indoor climate control, industrial IoT, precision monitoring
- VCC → Power supply input (works from 2.4 V – 5.5 V)
- GND → Ground (0 V reference)
- SDA → Serial Data (I²C data line, bidirectional)
- SCL → Serial Clock (I²C clock line, input)
Standard I²C requires pull-up resistors (usually 4.7 kΩ) on SDA and SCL. Some breakout boards already include them, but you should confirm. Connects easily to microcontrollers like Arduino (A4 = SDA, A5 = SCL), ESP32 (configurable pins), Raspberry Pi (GPIO 2 = SDA, GPIO 3 = SCL). Module size is 17 mm × 12 mm, and the 4-pin header follows a straight-line format.
