Compatibility
Works with Arduino, ESP32, Raspberry Pi, and any microcontroller with I2C. Logic-level compatible with both 3.3V and 5V systems. Libraries available for Arduino and CircuitPython.
Wiring Notes
Connect VCC to 3.3V or 5V, GND to GND, SDA and SCL to corresponding I2C pins. Most breakout boards include pull-up resistors; if not, add 4.7kΩ resistors to VCC. Keep sensor away from heat sources for stable readings.
Why Buy from Compoden
Every component is sourced from verified suppliers and tested for compatibility before listing. We've spent 10 years building projects for makers, schools, and institutions across India. Ships from Bengaluru in 3-5 days. If defective on arrival, replace within 7 days.
Is this compatible with Arduino Uno?
Yes, connect SDA to A4 and SCL to A5. Use the Adafruit SHT31 or Sensirion SHT3x library for quick integration.
Can it be used outdoors?
The module is not waterproof. Use in sheltered enclosures; protect from rain and direct sunlight for accurate long-term readings.
What is the typical measurement frequency?
The sensor can output data at up to 10 Hz in high-speed mode. Most example code reads at 1 Hz for a balance of speed and power.
