Description

The AHT30 Stainless Steel Probe integrates a high-performance AHT30 MEMS sensor chip within a sealed, waterproof stainless steel housing. This design protects the sensitive capacitive humidity sensing and band-gap temperature sensing elements from condensation, dust, and mild chemical exposure, making it suitable for long-term deployment in industrial and agricultural settings.

The sensor communicates via a two-wire I2C interface, providing fully calibrated digital output for both temperature and relative humidity. Its wide operating voltage range ensures compatibility with a broad spectrum of data acquisition systems, from battery-powered IoT nodes to mains-powered control panels. The attached 1-meter cable allows for remote placement of the sensing probe while maintaining signal integrity.

Key Features

  • High-Precision Sensing: Utilizes the AHT30 chip for accurate readings with ±0.3°C temperature and ±2% relative humidity accuracy.

Frequently Asked Questions

What is the operating voltage range for this AHT30 probe?

The probe operates from 3.0V to 5.5V DC. This wide range makes it directly compatible with both 3.3V systems (like ESP32 or Raspberry Pi) and standard 5V Arduino boards without requiring a logic level converter.

How do I connect and read data from this sensor?

The sensor uses a standard I2C interface. Connect the cable's VCC, GND, SDA, and SCL wires to your microcontroller. You can then use existing libraries for the AHT30 chip to read the calibrated digital temperature and humidity values over the I2C bus.

Is the stainless steel probe tip fully waterproof?

Yes, the stainless steel housing of the probe is sealed to be waterproof, protecting the internal AHT30 sensor chip from moisture and condensation. This allows it to be used in humid environments, though the cable connection point should be protected from direct immersion.

What is the accuracy and resolution of the measurements?

The sensor provides high-accuracy readings with ±0.3°C for temperature and ±2% RH for humidity. It also offers high resolution of 0.01°C for temperature and 0.024% RH for humidity, enabling detection of very fine environmental changes.
