DHT22 Temperature and Humidity Sensor (AM2302)

High-Precision DHT22/AM2302 Temperature and Humidity Sensor

The DHT22 digital sensor, also known as AM2302, is the ultimate environmental measurement tool for users seeking accuracy and reliability. This device is designed to capture the climatic conditions of any room with maximum fidelity, integrating natively into professional home automation systems.

Thanks to its capacitive sensor and thermistor technology, it offers superior stability compared to basic models, ensuring that your smart home data is always accurate.

Technical Performance in Demanding Conditions

This device stands out for its ability to operate in extreme ranges, allowing temperature monitoring from -40°C to 80°C and relative humidity measurement from 0% to 100%. Its technical precision is one of its greatest assets, with a minimal margin of error of just ±0.5°C for temperature and ±2% for humidity.

These specifications make it the ideal component for environments where climate control is critical, such as wine cellars, greenhouses, or computer server rooms.

Integration with Shelly Plus Add-on

The true power of this sensor is unleashed when connected to the Shelly Plus Add-on. Thanks to its single-bus communication protocol, integration is clean and direct. By combining the DHT22 with the Add-on, any device in the Plus or Gen3 range becomes an advanced weather station.

This configuration allows your Shelly system to make automatic decisions, such as activating an extractor fan if humidity rises excessively or turning on the heating if the temperature drops below a specific threshold.

Applications and Energy Efficiency

The DHT22's design is optimized for ultra-low power consumption, operating efficiently at a voltage of 3.3V to 5V.

Its versatility allows for applications ranging from domestic comfort in bedrooms to the supervision of light industrial processes.

By providing real-time data to the Shelly Smart Control App, this sensor facilitates the creation of smart scenes that not only improve well-being but also optimize energy use by activating climate control systems only when strictly necessary.
