SHT31 Soil Temperature & Humidity Sensor

High-Precision Digital Sensing Core: Employs Sensirion’s SHT31 sensor chip to deliver highly accurate, fully calibrated temperature and relative humidity telemetry.

Porous Sintered Metal Probe Protection: Housed in a durable sintered metal cap that allows moisture vapor to pass through while preventing dirt, soil, and large particles from damaging internal optics.

I²C Digital Communication Interface: Provides digitized, factory-calibrated output signals over a standard I²C bus with configurable address lines for multi-sensor setups.

Wide Thermal & Humidity Range: Accurately measures wide temperature and relative humidity ranges with rapid response times and high subterranean reliability.

Durable Weatherproof Cable Harness: Features an extended multi-core copper cable with protective outer jacketing and color-coded leads for easy connection to microcontrollers.

Housing Material: Heavy-duty sintered stainless steel filter body with copper internal wiring and protective PVC cable jacketing.

Technical Specifications:

Sensor Chip: Sensirion SHT31 Precision Digital Sensor.

Operating Supply Voltage: 2.4V – 5.5V DC (3.3V / 5.0V typical).

Interface Protocol: I²C Serial Interface.

Temperature Accuracy: ± 0.2°C.

Humidity Accuracy: ± 2% RH.

Color: Silver Sintered Metal Tip with Black Cable & Multicolor Terminal Wires.

Usage Advice: Connect VCC (3.3V/5V), GND, SDA, and SCL pins to your microcontroller; insert the sintered metal probe tip directly into the targeted soil matrix.

Maintenance: Do not leave the probe submerged in mud or standing water indefinitely; gently wipe off soil encrustations with clean water and allow the filter to air dry.

Essential High-Precision Agricultural Probe: Position as an upgraded, highly accurate soil temperature and humidity sensor for professional agricultural automation, greenhouses, and IoT weather stations.

Highlight Precision I²C & Sintered Filter: Emphasize how the SHT31 core combined with a porous metal filter provides lab-grade atmospheric and subterranean data without signal drift over long cable runs.

Recommended Cross-Sell Add-ons: Pair with SHT10 Soil Temperature & Humidity Sensor, 3-in-1 Integrated Sensor Temperature + Humidity + PH, Analog Capacitive Soil Moisture Sensor, and ESD antistatic mat 50x40CM PCB Welding Mat.
