SHT31-D Temperature and Humidity Sensor Breakout Digital Output Temperature and Humidity Sensor Module IIC I2C Interface
Specifications:
- Power supply voltage: 2.4-5.5V (typically 3.3V)
- RH response time: 8 seconds (tau63%)
- RH working range: 0-99.99%RH
- Operating temperature range: -40° to 125°C (-40° to 257°F)
- Precision tolerance: +/- 2%; RH +/- 0.3"
- Interface: I2C
Package Included:
4* SHT31-D Temperature Humidity Sensor
Power Pins:
- Vin - this is the power pin. The chip can use 2.5-5V DC for power. To power the board, give it the same power as the logic level of your microcontroller - e.g. for a 5V micro, use 5V. For a 3.3V controller, 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. Check the datasheet for how you can set up the alerts.
