Temperature/Humidity sensors are high-accuracy devices. The SHT31-D sensor features a true I2C interface for easy integration and offers ±2% relative humidity accuracy and ±0.3°C temperature 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 PCB is required but straightforward, even for beginners. Power Pins: - Vin – Power input; accepts 2.5–5V DC. Match the 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; includes a 10kΩ pull-up resistor to Vin. - SDA – I2C data pin; includes a 10kΩ pull-up resistor to Vin. Other Pins: - ADR – I2C address selection pin. Includes a 10kΩ pull-down resistor, defaulting to I2C address 0x44. Connect to Vin to change address to 0x45. - RST – Hardware reset pin. Includes a 10kΩ pull-up resistor, keeping the device active by default. Ground this pin to perform a hardware reset. - ALR – Alert/interrupt output. Configurable to trigger on specific sensor events (refer to the datasheet for setup details). Package Contents: - 1 × SHT31-D Temperature and Humidity Sensor Breakout Board Note: Color appearance may vary slightly due to lighting conditions and display settings.
