Description

Easy to use temperature and humidity sensor, powered by 3 V to 5.0 V. Communicates through an I2C interface. The accuracy is 0.3°C. The sensor is used, i.a. for meteorological stations and systems of control of the conditions in the premises.

 

Connection

For proper operation, it is sufficient to connect power and data line SDA and clock line SCL. On Board are resistors pulling-up 10 kω.

 

Adafruit SHT31

 

Pin Description
VIN Pin of the power supply from 3 V to 5 V.
GND The mass of the system.
SCL Clock line of I2C interface.
SDA Data line of I2C interface.
ADDR

The address selection I2C. Low state (by default) - 0x44

High - 0x45.

RST The reset of the module is activated by low state.
ALRT

The pin of the alarm and interruption. Details inthe documentation.

 

The product is compatible with Arduino

The manufacturer has prepared auser guideanda library along with a sample programfor Arduino users.

 

Pins are the solder fields, for solderinggoldpin connectors- pitch of 2.54 mm. Therefore, it is possible to connect the system with the breadboardor the main module, using wires. The set includes the goldpin connectors for self-soldering.
