SHT30
Description: Sensiron
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 SHT30-D sensor has an excellent ±2% relative humidity and
±0.3°C accuracy for most uses.
Unlike
earlier SHT sensors, this sensor has a true I2C interface, and (bonus!) even
with two address options. It also is 3V or 5V compliant, so you can power and
communicate with it using just about any microcontroller or
microcomputer.
Such
a lovely chip - so we spun up a breakout board with the SHT30-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 Ard uino, 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 line.
This
pin has a 10K pullup resistor to Vin
SDA
- I2C data pin, connect to your microcontrollers I2C data line.
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 on it to make the chip active by
default. Connect to ground to do a hardware reset!
ALR
- Alert/Interrupt output. You can set up the sensor to alert you when an event
has occured. Check the datasheet for how you can set up the
alerts
