Temperature/Humidity sensors offer high accuracy and reliability. The SHT31-D sensor features a true I2C interface for easy integration and delivers ±2% relative humidity and ±0.3°C accuracy. Material: Plastic Color: Purple This breakout board includes the SHT31-D sensor with supporting circuitry, including pull-up resistors and capacitors. Each order includes one fully assembled and tested PCB breakout board and a short length of header pins. Soldering the header to the board is required but straightforward—even for beginners. Power Pins: - Vin: Power input (2.5–5V DC). Match voltage to your microcontroller’s logic level (e.g., 5V for Arduino, 3.3V for Raspberry Pi). - GND: Common ground for power and logic. I2C Logic Pins: - SCL: I2C clock pin—connect to your microcontroller’s I2C clock line. Includes a 10kΩ pull-up resistor to Vin. - SDA: I2C data pin—connect to your microcontroller’s I2C data line. Includes a 10kΩ pull-up resistor to Vin. Other Pins: - ADR: I2C address selection pin. Default address is 0x44 (10kΩ pull-down to GND). Tie to Vin for address 0x45. - RST: Hardware reset pin. Includes a 10kΩ pull-up resistor—connect to GND to reset. - ALR: Alert/Interrupt output. Configurable via register settings (refer to datasheet). Package Contents: - 1 × SHT31-D Temperature and Humidity Sensor Breakout Board Note: Actual product color may vary slightly due to lighting conditions and screen settings.
