Opening it shows a confirmation page with live pricing and stock before anything is added to the cart. - **Verify the cart first:** fetch `https://core-electronics.com.au/cart/link/SEN0334:1.md` for live line prices (inc & exc GST, quantity discounts applied), stock and dispatch estimates, and totals. Append `/to/{AU-postcode}` (or `/to/{country-code}:{postcode}`) before `.md` for delivery options and prices to that destination. Unknown, retired, or out-of-stock SKUs are flagged. (Query form `cart/link.md?items=...` also works but some robots parsers refuse query strings here.) - **Checkout** is completed on-site and includes a captcha at the payment step. Share the cart link; checkout takes it from there. - **Search the catalogue:** `https://core-electronics.com.au/search/{query}.md` (URL-encode the query; pages 2-3 at `search/{query}/{page}.md`; `search.md?q=` also works) - **Payment methods, purchase orders, policies and contact details:** https://core-electronics.com.au/llms.txt ## Description ### Introduction Gravity: SHT31-F digital temperature and humidity sensor is based upon the Sensirion SHT31-F sensor IC. Thanks to Sensirion’s CMOSens® technology, highly integrated capacitive humidity sensing components and band-gap temperature sensing components, the SHT31-F offers high reliability and long-term stability with low power consumption, fast response and strong anti-interference ability. The sensor supports I2C communication, and is compatible with 3.3V/5V controllers like [Arduino](https://www.dfrobot.com/category-104.html),[ micro:bit,](https://www.dfrobot.com/category-257.html) [ESP32](https://www.dfrobot.com/category-271.html). It is easy to achieve precise and high-reliability temperature and humidity sensing for urban environment monitoring, intelligent buildings, industrial automation, smart home and other Internet of Things applications. SHT31-F is the standard version of the SHT3x series. It provides humidity accuracy ±2% RH @ 0%RH~100%RH (at 25°C), and temperature accuracy±0.2°C @ 0°C - 90°C (typical). The SHT31-F chip features a PTFE membrane dedicated to protecting the sensor opening from liquids and dust according to IP67. It thus allows the [sensor](https://www.dfrobot.com/category-36.html) to work under harsh environmental conditions, where spray water and high exposure to dust might be challenging for accurate sensor performance. Due to minimal package volume and the membrane’s high water vapor permeability, the response time of the relative humidity and temperature signal is identical to the value achieved by the uncovered sensor. Although the membrane option provides perfect protection against water and dust ingress, it does not in general prevent contamination from volatile chemicals. ### Features - High precise, internal auto-calibrated, digital output - Low power consumption, fast response, and strong anti-interference - IP67 dust-proof protective film - Compatible with 3.3V/5V controllers ### Applications - Urban Environmental Monitoring - Intelligent Building, Smart Home - Grain Storage - Plant and animal breeding system ### Specification - Operating Voltage: 3.3~5.5V - Operating Current: <1.5mA - Humidity Detection Range: 0%RH~100%RH - Humidity Accuracy: ±2%RH@10%RH~90%RH(at 25°C) - Temperature Detection Range: -40°C ~ 125°C - Temperature Accuracy: ±0.2°C@0°C~90°C (Typical) - Communication: I2C - Outline Dimension: 32x22mm/1.26x0.87” - Mounting Hole Size: 3mm/0.12” - Mounting Hole Pitch: 15mm/0.59” ### Documents 17.
