Unlike previous SHT sensors, this sensor features a true I2C interface and even two address options. It's also 3V or 5V compatible, so you can run and communicate with almost any microcontroller or microcomputer. Power Pins:Vin - this is the power pin. The chip can use 2.5-5VDC for power supply. To power the board, give it the same voltage as your microcontroller's logic level - e.g. for a 5V microcontroller like for Arduino, use 5V. For a 3.3V controller like a Raspbery Pi, connect to 3.3V GND - common ground for power and logic SCL - I2C clock pin, connect it to the I2C clock line of your microcontroller. This pin has a 10K pullup resistor against VinSDA - I2C data pin, connects to the I2C data line of the microcontroller. This pin has a 10K pullup resistor to VinADR - This is the I2C address select pin. This pin has a 10K pull-down resistor to set the default I2C address 0x44. You can connect this pin to Vin to set address 0x45.RST - Hardware reset pin. Has a 10K pullup resistor to make the chip active by default. Connect to ground to perform a hardware reset!ALR - Alarm\/Interrupt output. You can set the sensor to alert you when an event has occurred. Refer to the datasheet to learn how to set up the alerts.\u003c\/p\u003e \u003ch3\u003eProduct Features\u003c\/h3\u003e \u003cul class=\"a\"\u003e \u003cli\u003eI2C interface with communication speeds
