How It Works
- Temperature & Humidity Measurement: The sensor uses a capacitive humidity sensor and a thermal resistor to detect the environmental conditions.
- Data Transmission: The single-wire communication allows the sensor to send temperature and humidity data to the microcontroller at regular intervals.
- Output: The digital output is processed by the microcontroller, which can then convert the signal into meaningful temperature and humidity readings.
- Calibration: The sensor is factory-calibrated, which makes it easy to integrate into projects without the need for extra calibration.
Applications
- 🌡️ Weather Stations – Monitor temperature and humidity levels for climate tracking.
- 🏠 Home Automation – Control air conditioning or heating based on environmental conditions.
- 🌱 Greenhouse Monitoring – Optimize conditions for plant growth by monitoring the environment.
- 🧳 Data Logging – Collect environmental data for research or projects.
- 🏥 Indoor Air Quality – Measure temperature and humidity for HVAC systems or health monitoring.
