Description: 1. DHT11 is a popular low-cost digital temperature and humidity sensor module based on the RH22 series humidity sensor and a thermistor for temperature measurement. 2. Features: It measures relative humidity (0-100%) and temperature (0°C to 50°C) with an accuracy of ±2% RH and ±1°C for temperature. It uses a single-wire communication protocol to transmit data. 3. Operation: The sensor module requires a power supply (3.3V-5V) through a 4.7kΩ resistor in series with the VCC pin, and a 10kΩ resistor between the data and VCC pins for proper operation. 4. Data Transmission: DHT11 sends out the data once when requested via a data pin (usually connected to an Arduino's digital input pin). It does not continuously transmit data, conserving power usage. 5. Ease of Use: This sensor module is simple and straightforward to use with most microcontrollers and development boards, especially those using the Arduino platform, thanks to numerous libraries and example codes available online. 6.
