The AM2320 temperature and humidity sensor is an integrated temperature and humidity sensor with calibrated digital signal output. It uses a high-precision capacitive humidity-sensing element and an NTC temperature-measuring element, and fuses the data of the two through a patented temperature and humidity compensation algorithm. Its core advantage is converting analog signals into I2C digital protocol output, enabling direct communication with microcontrollers or microprocessors, and eliminating the need for the A/D conversion circuit required by traditional sensors.
Core Advantage:
- Ultra-small size:The module size is only about20×15mm, which can be easily embedded in small devices (such as smart watches and miniature monitors).
- Digital output: AdoptsI2C bus communication, no need for analog signal conversion, ensuring more accurate data.
- Wide range adaptation:Humidity measurement range is 0-100% RH,and temperature measurement range is –40°C ~ 80°C.
- Waterproof and moisture-proof:The sensor probe is treated for moisture resistance and can be in contact with humid environments (such as bathrooms and flower pot soil) for a short time.
- High accuracy: Humidity accuracy is±2% RH, and temperature accuracy is±0.5°C, meeting the needs of accurate monitoring in most scenarios.
- Strong anti-interference ability:Digital signal transmission is not easily affected by electromagnetic interference (analog signals are easily interfered by wires).
- Simple wiring: Only 4 wires (or 3 wires) are needed for communication, allowing beginners to get started quickly.
- Low power consumption: The standby current is only0.1μA, suitable for battery-powered portable devices.
