Temperature and Humidity Sensor

Product Description

The AM2301 is a digital temperature and humidity module that integrates a calibrated capacitive humidity sensor and a high-precision temperature measurement device. It features a single-bus interface for simplified communication, ultra-low power consumption, and a compact design. The sensor is factory-calibrated with coefficients stored in its microcontroller, ensuring high reliability and long-term stability. It is suitable for a wide range of applications due to its fast response, anti-interference capability, and transmission distance of up to 20 meters.

Key Features

• Digital Output: Single-bus interface for easy integration.
  
• High Accuracy:Humidity: ±3% RH (at 25°C), 0.1% resolution.Temperature: ±0.3°C (typical), 0.1°C resolution.
  
• Wide Operating Range:Humidity: 0–99.9% RH.Temperature: -40°C to 80°C.
  
• Low Power Consumption:Sleep mode: 10–15 µA.Average: 300 µA (at 5V, 25°C).
  
• Fully Interchangeable: No need for individual calibration.
  
• Robust Performance:Fast response time (<6s for humidity, <10s for temperature).Excellent long-term stability (<0.5% RH/year drift).
