What is the DHT11 Module?
The DHT11 is a temperature and humidity sensor that combines advanced sensing technology with a calibrated digital output. Designed for simplicity and efficiency, this module operates on a voltage range of 3.3V to 5.5V DC and consumes minimal power.
- Current Consumption:
- Active Mode: 0.3mA while measuring temperature and humidity.
- Standby Mode: Only 60 microamperes.
- Measurement Range:
- Temperature: 0°C to 50°C.
- Humidity: 20% to 90%.
- Sensor Type: Utilizes an NTC Thermistor (Negative Temperature Coefficient) for temperature measurement.
- Pins: The module has three pins – + (VCC), – (GND), and OUT (Data).
The DHT11 module is known for its long-term stability, ease of use, and reliability, making it a popular choice for projects requiring environmental data monitoring.
