Take your next outdoor sensor project to the next level with this SHT-30 based temperature/humidity sensor. The sensor includes a dual-use sensor module from Sensiron in a sintered metal mesh encasing. The casing is weatherproof and will keep water from seeping into the body of the sensor and damaging it, but allows air to pass through so that it can measure the humidity outside. While it is designed to be submersible in water, it's always best to avoid long-term submersion (over 1 hour at a time), and it obviously would only give you temperature readings. For that, our metal-cased temperature sensors would be better! This sensor is best for simply placing outside for exterior weather sensing.
The SHT30-D sensor has an excellent ±2% relative humidity and ±0.5°C accuracy for most uses. Unlike earlier SHT sensors, this sensor has a true I2C interface.
The sensor is essentially just a Sensiron SHT-30 digital sensor (much like our breakout here) with the 4 data/power wires brought out so any SHT-3x code for a microcontroller will work. Check out the tutorial for Arduino and CircuitPython/Python, and more!
The 1 meter long cable has four wires: Brown = VCC (3-5VDC), Black = Ground, Yellow = Clock, Blue = Data.
Jargon buster
Plain-language definitions for the technical terms used above.
- breakout
- A breakout is a small circuit board that makes a tiny or hard-to-solder component easier to connect to with standard pins. It matters because this OLED module can be wired into a microcontroller project without needing to solder directly to the display’s fine contacts.
- I2C
- I2C is a two-wire communication bus used by many sensors and small modules. It matters because several I2C devices can share the same two wires, but each device needs a compatible address and your controller must support I2C.
- microcontroller
- A microcontroller is a small computer on a chip that runs your program and controls connected inputs and outputs. For this product, it is the part that reads buttons and sensors, drives the display and speaker, and communicates over Bluetooth.
