Specification:
RH response time: 0-100% RH
Interface: I2C
Colour:Purple
Material:Plastic
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 level of your microcontroller - e.g.for a 5V Mini like for , use 5V.For a 3.3V controller like a Pi, connect to 3.3V GND - common ground for power and logic.
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.
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.
Package Includes:
1 x SHT31-D Sensor Module
1 x 4-pin header
10 x Male and female cable

取説もなく、アドレスも不明でしたが、0x44で正常に動作しました。writeコマンドの後にreadを2回すると、コマンドタイムアウトとなり、以後正常に動かなくなりますが、システムをオフし、オンすると正常に動作しました。
