Compact temperature and humidity sensor module based on the Sensirion SHT4x series.
Status: Beta
This board provides accurate temperature and relative humidity measurements over I2C.
- Sensor: SHT4x
- Interface: I2C
- Default Address:
0x44 - Voltage: 3.3V only
- High accuracy temperature and humidity sensing
- Mechaxil 4-wire I2C connector (JST-XH-S4B)
- M3 Mounting holes for easy integration
SDA - +3V3 - GND - SCL
-
Designed for robust I2C communication
-
Compatible with:
- Single wires
- Ribbon cables
- Do Not use twisted pair cable, if you want to use it pair SDA and SCL only with GND read more about it in section 7.5 in NXP UM10204 Documenation
