SHT31 Temperatur & SHT31-D Luftfeuchtigkeitssensor Modul Breakout Wetter
SHT31 Temperature & SHT31-D Humidity Sensor module Breakout Weather for Arduino 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. PINS: 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 AD - 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 AL - Alert / Interrupt output. You can set.
