Product Description
Product Description
The DFRobot Fermion AHT20 temperature and humidity sensor module SEN0527 is a compact sensor module for measuring temperature and relative humidity. Its breakout-format design simplifies integration into prototypes, measurement systems, and embedded applications that require a digitally connected environmental sensor.
The module uses the AHT20 sensor IC. It is designed for a 2 to 5 V supply and communicates via an I2C interface. With its compact footprint and exposed SDA, SCL, GND, and VCC connections, the module can be integrated into microcontroller-based systems with minimal wiring effort.
Technical Features
- Temperature and humidity sensor module based on the AHT20 sensor IC
- Digital I2C communication for connection to microcontrollers and embedded systems
- Supply voltage range: 2 to 5 V
- Compact breakout form factor for development, testing, and integration
- 4-pin connection layout: SDA, SCL, GND, VCC
- Part of the DFRobot Fermion module series for general electronics and sensing tasks
Application Areas
Typical application areas include environmental monitoring, data logging, indoor climate measurement, laboratory setups, education projects, and IoT or microcontroller-based systems. The module can be used in fixed sensing nodes, prototypes, and compact control systems where temperature and humidity data must be acquired digitally and processed further.
Its I2C interface makes it suitable for systems with limited pin availability and for designs where multiple digital devices share a common bus. The breakout implementation supports quick evaluation on breadboards or integration into custom PCBs.
