DHT11 Temperature And Humidity Sensor Module with LED
Description:
The DHT11 Temperature and Humidity Sensor Module with LED is a compact and cost-effective sensor module designed to measure temperature and humidity in the surrounding environment. Here's a description of its use and features:
-
Sensor Functionality:
- The DHT11 sensor is capable of measuring both temperature and humidity levels.
- It uses a digital signal output, making it easy to interface with microcontrollers and other digital circuits.
-
Measurement Range:
- Temperature: The DHT11 typically has a temperature measurement range of 0°C to 50°C with an accuracy of ±2°C.
- Humidity: It can measure relative humidity in the range of 20% to 90% with an accuracy of ±5%.
-
Digital Output:
- The DHT11 sensor communicates with the microcontroller using a single-wire digital interface. This interface simplifies the integration of the sensor into projects, as it requires minimal wiring.
-
LED Indicator:
- Many DHT11 sensor modules come equipped with an LED indicator. This LED often serves as a status indicator, providing visual feedback on the sensor's operation.
- For example, the LED might blink to indicate that the sensor is actively taking readings or to signal an error condition.
-
Low Power Consumption:
- The DHT11 sensor operates on low power, making it suitable for battery-powered applications and projects where power efficiency is essential.
-
Applications:
- The DHT11 sensor module finds applications in various projects and systems where monitoring temperature and humidity levels is necessary. Some common applications include weather stations, environmental monitoring systems, HVAC (heating, ventilation, and air conditioning) systems, and incubators.
