Unlock New Capabilities

• Past Projects: If you've already experimented with basic indoor temperature and humidity sensors like the DHT11 or DHT22, you know how to display environmental data on an LCD or send it to an IoT dashboard. However, you've likely hit a wall when attempting to deploy those open-PCB sensors outdoors, in damp green houses, or near soil where water spray quickly causes corrosion or inaccurate readings.
• Feature Upgrade: This SHT30 Waterproof Sensor Probe unlocks continuous outdoor climate monitoring, automated greenhouse humidity control, cold chain storage tracking, and weather station datalogging. The 1-meter multi-core cable and IP67 sintered protective shell shield the sensitive capacitive element from direct rain and dust while still allowing air molecules to pass through for precise, real-time measurements.
• Effort Level & Minimum Hardware
• Effort Level: Intermediate

Minimum hardware to get started:

• Microcontroller (Arduino / ESP32): required to initiate I2C commands and process the digital temperature and humidity data packets.
• 2× 4.7kΩ Pull-up Resistors: strictly required on the SDA and SCL signal lines when using long lead wires like this 1-meter probe cable to prevent I2C bus noise and signal degradation.
• 5V DC Power Source or Micro USB Cable: necessary to supply steady power to the development board and sensor module.

Included in the Box:

• 1× Waterproof SHT30 Temperature & Humidity Sensor Probe with Integrated Cable

Frequently Asked Questions

• Is the SHT30 Waterproof Sensor Probe compatible with Arduino?
  Yes, it works directly with Arduino Uno, Mega, and Nano using standard I2C libraries.
• Can I use this waterproof probe with an ESP32 or ESP8266?
  Yes, it natively supports 3.3V power and logic, making it fully compatible with ESP32 and ESP8266 development boards.
• Does this sensor work with Raspberry Pi?
  Yes, you can wire it to the Raspberry Pi's I2C GPIO pins and read climate data using Python scripts.
• Can I connect multiple SHT30 probes to the same microcontroller?
  Yes, you can change the I2C address or use an I2C multiplexer (like the TCA9548A) to run multiple probe cables on one board.
• What is the operating voltage range for this SHT30 probe?
  The sensor operates across a wide input range from 2.4V to 5.5V DC.
• Can I power the sensor from a 3.3V supply?
  Yes, powering it with 3.3V is recommended when connecting to 3.3V logic boards like ESP32 or Raspberry Pi Pico.
• How much current does the probe draw during operation?
  It has extremely low current consumption, drawing only around 0.2mA to 1.5mA during active measurement cycles.
• How do I connect the 4-core cable to my microcontroller?
  Connect VCC to power, GND to common ground, and the SDA/SCL leads to your microcontroller's hardware I2C pins.
• Do I need external pull-up resistors for the I2C lines?
  Yes, you must add 4.7kΩ pull-up resistors between VCC and SDA/SCL to ensure clean signals over the 1-meter cable.
• Which Arduino library should I use to read temperature and humidity?
  The Adafruit SHT31 library is the most reliable choice and works seamlessly with SHT30 hardware.
• Is there example code available for MicroPython on the Pico or ESP32?
  Yes, open-source MicroPython drivers for the SHT30 are available on GitHub for simple integration.
• Can the sensor report temperatures in both Celsius and Fahrenheit?
  Yes, software libraries usually provide functions to retrieve readings in either °C or °F.
• Why is my microcontroller failing to detect the SHT30 on the I2C bus?
  Verify that you have installed 4.7kΩ pull-up resistors on SDA and SCL, and double-check your ground connections.
• Can the probe tip be fully submerged underwater continuously?
  The sintered PE cover is designed for high-humidity and rain/water spray environments (IP67 protection); long-term continuous liquid immersion should be avoided.
