AHT20-F High-Precision Miniaturized Digital Humidity Temperature Sensor For Consumer Electronics Industrial Automation

            AHT20-F High-Precision Miniaturized Digital Humidity Temperature Sensor For Consumer Electronics Industrial Automation

1. Core Product Features:

• High Measurement Accuracy: Delivers exceptional precision across typical operating ranges—humidity accuracy of ±2% RH (at 25℃, 20%-80% RH) and temperature accuracy of ±0.3℃ (at 25℃), ensuring reliable data for critical applications.
• Wide Detection Range: Adapts to diverse environmental conditions with a humidity measurement range of 0%-100% RH and a temperature measurement range of -40℃ to +85℃.
• Low Power Consumption: Features ultra-low power design—only 2.7μA in sleep mode and 70μA during active measurement (typical values at 3.3V), ideal for battery-powered devices (e.g., portable weather stations, smart wearables).
• Compact SMD Package: Utilizes a small SMD (Surface Mount Device) package (3mm × 3mm × 1.0mm), saving PCB space and simplifying automated assembly in high-volume production.
• Digital I2C Interface: Communicates via the industry-standard I2C bus (supporting 100kHz standard mode and 400kHz fast mode), enabling direct connection to microcontrollers (MCUs) like Arduino, STM32, and ESP32 without complex signal conversion.
• Built-in Self-Calibration: Equipped with on-chip factory-calibrated coefficients, eliminating the need for manual calibration by users and ensuring consistent performance across batches.
• Stable Long-Term Performance: The sensing element is protected by a robust encapsulation, resisting interference from dust, oil, and common chemicals, resulting in low drift and a long service life (typical 5 years under normal operating conditions).

2. Typical Applications:

• Consumer Electronics: Smart home devices (e.g., smart thermostats, humidifiers, air purifiers), wearable devices (e.g., fitness trackers, smart watches), and refrigerators (to monitor internal humidity/temperature).
• Industrial Automation: HVAC (Heating, Ventilation, and Air Conditioning) systems, warehouse environmental monitoring (for food, pharmaceuticals, or electronic components), and printing/packaging process control.
• Medical Equipment: Medical refrigerators, incubators, and wearable health monitors (to ensure stable environmental conditions for drugs or patient care).
• Agriculture & Horticulture: Greenhouse environmental monitoring (to optimize humidity/temperature for crop growth) and soil moisture-temperature integrated detection systems.
• Automotive Electronics: In-car air quality monitoring systems and battery management systems (to prevent condensation damage to electronic components).
