Has a 10K pullup on it to make the chip active by default. RH response time: 8 seconds (tau63%). ALR - Alert/Interrupt output. GY-SHT31-D Digital Temperature and Humidity Sensor SHT30/SHT31/SHT35 Digital Output Temperature and Humidity Sensor Module IIC I2C Interface 3.3V GY-SHT31-D For Arduino Color: GY-SHT35-D GY-SHT30-D GY-SHT31-D GY-SHT35-D 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 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. The gy-sht31-d temperature humidity sensor output is iic i2c interface, communication rate up to 1MHz, with two user-selectable addresses. SHT31-D Temperature Humidity Sensors Specifications: Power supply voltage: 2., 4-5., 5V (typically 3., 3V) RH response time: 8 seconds (tau63%) Operating temperature range: -40° to 125°C (-40° to 257°F) Precision tolerance: +/- 2%; RH +/- 0., 3 Interface: I2C Power Pins: Vin - this is the power pin., The chip can use 2., 5-5V DC for power. You can set up the sensor to alert you when an event has occured. What is the SHT31 Temperature Humidity Sensor? SHT31 is a highly accurate, quick response, reliable, integrated temperature and humidity sensor. The sensor within the module is mainly designed with Sensirion's CMOSens® technology so, it is linearized, well-calibrated, and compensated primarily in digital output Check the datasheet for how you can set up the alerts Package Included: 4* SHT31-D Temperature Humidity Sensor I2C Digital Sensor 35057 Sht31 Temperature And Humidity Sensor Module I2c Communication Digital Dis GY-SHT31-D Sensor Module
