{"product_id":"sht31-sht31-d-temperature-humidity-sensor-module-for-arduino","title":"Sht31 Sht31-d Temperature \u0026 Humidity Sensor Module for Arduino","description":"Temperature\/Humidity sensors are some of the finest \u0026amp; highest-accuracy devices you can get. And, finally we have some that have a true I2C interface for easy reading. The SHT31-D sensor has an excellent +\/-2% relative humidity and +\/-0.3 Celsius accuracy for most uses.Material: plasticcolor: purpleSuch a lovely chip - so we spun up a breakout board with the SHT31-D and some supporting circuitry such as pullup resistors and capacitors. Each order comes with one fully assembled and tested PCB breakout and a small piece of header. You'll need to solder the header onto the PCB but it's fairly easy and takes only a few minutes even for a beginner.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 micro like Arduino, use 5V. for a 3.3V controller like a Raspbery Pi, connect to 3.3VGND - common ground for power and logicI2C Logic pins: SCL - I2C clock pin, connect to your microcontrollers I2C clock line. This pin has a 10K pullup resistor to VinSDA - I2C data pin, connect to your microcontrollers I2C data line. This pin has a 10K pullup resistor to VinOther Pins: 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 0x45RST - Hardware reset pint. Has a 10K pullup on it to make the chip active by default. Connect to ground to do a hardware reset\nALR - 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 alertsPackage Included: 1 X SHT31-D Temperature Humidity SensorOnly the above package content, other products are not included.Note: Light shooting 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.","brand":"FR-YISHENG","offers":[{"title":"Default Title","offer_id":43919179940035,"sku":"FR-YISHENG-007991","price":304.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0661\/4355\/1683\/files\/jpg_a1350c9a-6c1a-49d8-85d9-80f0a0f825a0.jpg?v=1725486662","url":"https:\/\/wrsss.com\/products\/sht31-sht31-d-temperature-humidity-sensor-module-for-arduino","provider":"Wrsss","version":"1.0","type":"link"}
