4X SHT31 SHT31-D Temperature & Humidity Sensor Breakout Board Weather Module for Popis

Temperature/Humidity sensors are some of the finest & highest-accuracy devices you can get. And, finally we have some that have a true I2C interface for easy reading. The SHT31-D sensor has an excellent +/-2% relative humidity and +/-0.3 Celsius accuracy for most uses.
Material: plastic

Such a lovely chip - so we spun a breakout board with the SHT31-D and some supporting circuitry such as pullup resistors and capacitors. Each order comes with one fully assembled and tested PCB breakout and a small piece of header. You'll need to solder the header onto the PCB but it's fairly easy and takes only a few minutes even for a beginner.

Power Pins:
Vin - this is the power pin. 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 - e.g. for a 5V micro like , use 5V. For a 3.3V controller like a Raspbery Pi, connect to 3.3V
GND - common ground for power and logic
I2C Logic pins:
SCL - I2C clock pin, connect to your microcontrollers I2C clock . This pin has a 10K pullup resistor to Vin
SDA - I2C data pin, connect to your microcontrollers I2C data . This pin has a 10K pullup resistor to Vin
Other Pins:
ADR - This is the I2C address selection pin. This pin has a 10K pull down resistor to make the default I2C address 0x44. You can tie this pin to Vin to make the address 0x45
RST - Hardware reset pint. Has a 10K pullup it to make the chip active by default. Connect to ground to do a hardware reset!
ALR - Alert/Interrupt output. You can set the sensor to alert you when an event has occured. Check the datasheet for how you can set the alerts
