3pcs Sht31-d Temperature Humidity Sensor Digital Output Sensor Module Iic I2c Interface 3.3v For leírása

Supply voltage range: 2.4 to 5.5V (typically 3.3V) RH working range: 0-99.99%RH ; I2C interface, communication rate up to 1MHz, with two user-selectable addresses Operating temperature range: -40 to 125Celsius (-40 to 257Fahrenheit) RH response time: 8 seconds (tau63%) Typical accuracy is +/- 2% RH and +/- 0.3 inch with high accuracy Sensor Manufacturer: #SHT31-DIS RH response time: 0-100% RH Interface: I2C Power 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 logic 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 - 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 - 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 Colour:Photo Color Material:plastic Package Contents: 3 x SHT31-D Temperature Humidity Sensor Only the above package content, other products are not included. Note: Light and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
