The DHT11 Temperature and Humidity Sensor measures temperature from 0°C to 50°C with ±2.0°C accuracy and humidity from 20% to 90% RH with ±5.0% RH accuracy, operating from 3.3V to 5V. The dht11 sensor shares the same single-wire digital communication protocol as the DHT22, readable through the same Arduino DHT library, but with narrower measurement ranges and lower precision — positioning it as the budget-friendly entry point into the DHT sensor family for indoor projects.
The dht11 temperature and humidity sensor’s 0-50°C range comfortably covers typical indoor room temperatures but cannot measure freezing or sub-zero conditions, unlike the DHT22’s -40°C to 80°C range — for outdoor or extreme-temperature monitoring, the DHT22 remains the better choice, while this dht11 humidity sensor suits indoor room comfort, classroom, and basic weather demo projects where 0-50°C is sufficient.
the dht11 sensor 4 pins package, like the DHT22, requires a 10kΩ pull-up resistor on the data line and a minimum sampling interval between reads — but its lower price makes it the more economical choice for beginner Arduino projects where DHT22’s wider range isn’t needed. Available from StemVolt, this DHT11 temperature and humidity sensor is ideal for students and enthusiast developing weather stations, environmental monitoring, IoT, and smart automation projects with reliable climate sensing capabilities.
