Temperature/Humidity sensors offer high accuracy. The SHT31-D sensor provides ±2% relative humidity and ±0.3°C temperature accuracy. Material: plastic Color: purple This breakout board features 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 PCB is required but straightforward, even for beginners. Power Pins: - Vin: Power input; accepts 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 line. Includes a 10kΩ pull-up resistor to Vin. - SDA: 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 per the datasheet. Package Contents: - 1 × SHT31-D Temperature and Humidity Sensor Breakout Board Note: Color appearance may vary slightly due to lighting and display differences.
