• Industrial Grade Accuracy & 16-Bit Resolution Equipped with the high-performance AM2302 sensor, this module delivers exceptional precision with ±0.5°C temperature tolerance and ±2% RH humidity tolerance. The 16-bit resolution ensures you capture the slightest environmental changes, making it ideal for data logging, greenhouse monitoring, or HVAC projects.
• Convenient 3-Pack for Multi-Point Monitoring This bundle includes three individual sensors, offering great value for complex projects. Monitor temperature and humidity in multiple locations simultaneously—such as different zones in an incubator, server racks, or rooms—without the need to purchase separate kits.
• Wide Voltage Compatibility (3V-5.5V) Designed for maximum flexibility, the sensor supports a wide operating voltage range from 3V to 5.5V. It works seamlessly with both 3.3V logic systems (like ESP32, Raspberry Pi) and 5V systems (like Arduino Uno) without requiring additional level shifters.
• Digital Signal Output for Stable Transmission Featuring a digital signal output, this sensor provides strong anti-interference capability. Unlike analog sensors, it maintains data integrity and stability even over longer wire distances, ensuring reliable performance in electrically noisy environments.
• Compact Design with Convenient Mounting Holes Designed for practical installation, each board includes 2.6mm mounting holes for secure screw fixation. With a compact size of 28.2mm x 13.1mm x 5.5mm and a lightweight design (6g), it is easy to mount inside enclosures, on walls, or onto equipment frames.
