Fully Calibrated Signal Output: Features onboard linearized digital signal processing with full internal calibration, eliminating the need for manual user calibration routines.

Fast Response Time & High Immunity: Designed with high noise immunity and fast thermal response times, ideal for environmental monitoring and HVAC automation nodes.

Compact Breakout Board Design: Mounted on a small purple breakout PCB equipped with 0.1" pitch pin headers for quick integration on breadboards and custom prototyping shields.

Board Material: High-grade FR-4 glass-epoxy breakout PCB with purple solder mask, gold-plated header pads, and onboard pull-up resistors.

Technical Specifications:

Sensor Element: Sensirion SHT30 Digital Temperature & Humidity IC.

Operating Voltage: 2.4V – 5.5V DC (Optimized for 3.3V logic systems).

Temperature Measurement Range: -40°C – +125°C (-+ 0.2°C typical accuracy).

Humidity Measurement Range: 0% – 100% RH (-+ 2% RH typical accuracy).

Communication Protocol: I2C Bus.

Board Color: Purple PCB with White Silk-Screen Markings.

Usage Advice: Connect SDA and SCL to your host microcontroller's I2C bus; ensure standard I2C pull-up resistors are active on the data lines.

Maintenance: Keep the central white sensor aperture free from dust, condensates, and aggressive chemical solvent fumes to prevent calibration drift.

Essential High-Accuracy Climate Sensor: Position as a reliable, high-precision upgrade over entry-level DHT sensors for smart thermostats, incubators, weather stations, and indoor air quality devices.

Highlight Plug-and-Play I2C Bus Integration: Emphasize how the digital I2C bus output and widespread library support simplify code development for ESP32, Arduino, and Raspberry Pi platforms.

Recommended Cross-Sell Add-ons: Pair with HTU21D Temperature & Humidity Sensor, AHT10 - temperature and humidity sensor, AM2302 (DHT22) Temp & Humidity Sensor, and ESD antistatic mat 50x40CM PCB Welding Mat.
