Certification:NONE
Temperature/humidity sensors are some of the best and highest accuracy devices you can get. Finally, we have some that have a real I2C interface for easy reading. The SHT30-D sensor has excellent ±2% relative humidity and ±0.3°C accuracy in most applications.
Unlike earlier SHT sensors, this sensor has a true I2C interface and even has two address options (plus!). It's also 3V or 5V compatible, so you can use any microcontroller or microcomputer to power it and communicate with it.
Such a lovely chip - so we started a breakout board with the SHT30-D and some support circuits like pull-up resistors and capacitors. Each order comes with a fully assembled and tested PCB socket and a small header. You'll need to solder the headers to the PCB, but it's fairly easy and only takes a few minutes, even for beginners.
Power pins:
Vin - This is the power pin. The chip can use 2.5-5VDC as power supply. To power the board, give it the same power as the logic level of the microcontroller. For 5V mini like Arduino, use 5V. For 3.3V controllers like Raspbery Pi, connect to 3.3V
GND - common ground for power and logic
I2C logic pins:
SCL - I2C clock pin, connect to your microcontroller's I2C clock line.
This pin has a 10K pull-up resistor to Vin
SDA - I2C data pin, connect to your microcontroller I2C data line.
This pin has a 10K pull-up resistor to Vin
Other pins:
ADR - This is the I2C address select pin. This pin has a 10K pull-down resistor, making the default I2C address 0x44. You can bind this pin to Vin, making address 0x45
RST - Hardware reset point. There's a 10K pull-up on it, making the chip active by default. Connect to ground and do a hardware reset!
ALR - Alarm/Interrupt output. You can set up sensors to alert you when events occur. Check the datasheet to learn how to set up alerts
