Youmile 2.5V 5V SHT31 Temperature and Humidity Sensor Module Digital Output IIC I2C Interface 3.3V GY D with male female Dupont cables for Arduino

【Power supply suggestion】：The chip can use 2.5-5VDC for power. To power the board, give it the same power as the logic level of your microcontroller-eg for a 5V micro, use 5V. For a 3.3V controller, connect to 3.3V GND-common ground for power and logic. 【High-quality products】：GY-SHT31 Temperature/Humidity sensors are some of the finest and highest-accuracy devices you can get and it has an excellent ±2% relative humidity and ±0.3°C accuracy for most uses. 【Compatibility】：Wide supply voltage range of 2.5 V to 5.5 V ensures compatibility with a wide range of assembly conditions. So you can use any microcontroller or microcomputer to power and communicate. 【Optional】：Features include enhanced signal processing, two unique user-selectable I2C addresses and communication speeds up to 1 MHz. 【Overall advantages】：a combination of multiple functions and various interfaces (I2C, voltage output) and a friendly, wide operating voltage range (2.5 to 5.5V). These sensors are suitable for a variety of high-volume and small-volume applications
