DHT11 Sensor Module

The DHT11 Sensor Module is a basic, ultra-low-cost digital temperature and humidity sensor designed for environmental monitoring applications. It uses a capacitive humidity sensor and a thermistor to measure the surrounding air and outputs a digital signal on a single data pin, making it easy to integrate with Arduino, ESP8266, ESP32, Raspberry Pi, and other microcontrollers.

Perfect for weather stations, smart farming, home automation, and IoT systems, the DHT11 offers reliable measurements with low power consumption and compact design. It comes pre-calibrated and requires minimal components to get started.

Key Features:

• ✅ Temperature & Humidity Measurement
  Measures temperature from 0°C to 50°C and humidity from 20% to 90% RH.

• ✅ Digital Output (Single-Wire Interface)
  Easy to read using one digital pin; supports popular libraries like DHT.h on Arduino IDE.

• ✅ Pre-Calibrated & Ready to Use
  No need for complex setup or calibration—just plug and play.

• ✅ Stable & Reliable Performance
  Ideal for continuous environmental monitoring in indoor and light outdoor conditions.

• ✅ Low Power Consumption
  Suitable for battery-powered and energy-efficient IoT projects.

• ✅ Compact Module with Mounting Holes
  Designed for quick prototyping and permanent installations alike.
