Product Parameters Power Supply: 3.3V–5.5V DC (regulated; do not exceed\r\n5.5V) Measurement Range: Humidity: 20%–90% RH (accuracy ±5%) Temperature:\r\n0°C–50°C (accuracy ±2°C) Resolution: Humidity 1% RH, Temperature 1°C Output\r\nSignal: Single-wire digital signal (calibrated) Sampling Period: ≥2 seconds\r\n(min interval between readings) Current Consumption: 0.5mA (average, 5V\r\nsupply) Dimensions: Standard PCB module with pre-soldered Dupont wires. 2. Key\r\nPin Functions Power Management: VCC: Positive supply input (connect to\r\nregulated 3.3V\/5V source) GND: Ground reference (shared with host MCU) Data\r\nCommunication: DATA: Bidirectional serial data line (supports single-bus\r\nprotocol; requires 4.7kΩ pull-up resistor to VCC). Unused Pin: NC: No internal\r\nconnection (leave unconnected). 3. Common Issues \u0026amp; Solutions Q1: Sensor fails\r\nto return data or shows \"NA\" on host? ① Verify pull-up resistor (4.7kΩ)\r\nbetween DATAand VCC; ② Ensure power stability (ripple \u0026lt;50mV); ③ Wait ≥1s after\r\npower-on before initializing communication. Q2: Humidity readings fluctuate\r\nexcessively? ① Avoid airflow sources (fans\/vents); ② Prevent condensation\r\n(operate within 20–90% RH); ③ Calibrate with known references if ±5% RH\r\naccuracy is insufficient. Q3: Temperature inaccuracies in high-heat Enviro\r\nnments? ① Keep sensor ≥5cm from heat-generating components (e.g., CPUs); ②\r\nShield from direct sunlight; ③ Use external NTC thermistor for \u0026gt;50°C\r\napplications.\u003c\/p\u003e \r\n\r\n\u003ch3\u003eProduct Features\u003c\/h3\u003e\r\n  \u003cul class=\"a\"\u003e\r\n         \u003cli\u003eHigh Accuracy Enviro nmental Monitoring Humidity 20%90% RH; temperature 0C50C; 1% RH resolution; 5% RH accuracy; 2C temperature accuracy\u003c\/li\u003e\r\n         \u003cli\u003eLow Power Consumption for Long-Term Use 0.5mA average current; 2000mAh battery compatible; 72-hour operation; 1.8A sleep mode; 3.3V5.5V DC power range\u003c\/li\u003e\r\n         \u003cli\u003eRobust Digital Interface with Reliable Communication Single-wire digital output; 4.7k pull-up resistor required; 2-second sampling interval; error-checking protocol included\u003c\/li\u003e\r\n         \u003cli\u003eEasy Integration with Popular Development Platforms Compatible with Arduino, Raspberry Pi, STM32; pre-soldered Dupont wires; simple setup; no external components needed\u003c\/li\u003e\r\n         \u003cli\u003eDesigned for Stable Performance in General Applications Operate within 20%90% RH; avoid direct sunlight; shield from heat sources; suitable for home automation, weather stations, and Enviro nmental monitoring\u003c\/li\u003e\r\n  \u003c\/ul\u003e","brand":"MusRock","offers":[{"title":"Default Title","offer_id":44154072301748,"sku":"B0FMR373CB","price":100.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0595\/9906\/1172\/files\/B0FMR373CB.jpg?v=1775785041","url":"https:\/\/auspowers.com\/products\/5pcs-dht11-humidity-temperature-sensor-module-0-50-c-2-c-20-90-rh-5-rh-single-wire-digital-signal-for-arduino-raspberry-pi","provider":"AusPower Australia","version":"1.0","type":"link"}
