About this item
🌡️ DHT11 Temperature & Humidity Sensor Module
💡 Digital Sensor for Environmental Monitoring
The DHT11 is a basic, ultra-low-cost digital temperature and humidity sensor. It uses a capacitive humidity sensor and a thermistor to measure the surrounding air and outputs the data via a single digital pin.
🛡️ Built-In Digital Interface
- 🔌 Single-wire digital communication
- 📏 Factory calibrated for reliable accuracy
- ⚡ Operates at 3.3V to 5.5V
- 🔧 Comes on a breakout board with pull-up resistor
📦 Compact & Easy to Use
This module is ideal for Arduino, ESP32, Raspberry Pi, and other microcontrollers. It requires minimal external components and is perfect for hobbyists, educators, and DIY environmental monitoring.
🛠️ Applications
- 🌿 Smart agriculture and greenhouses
