The DHT11 Temperature And Humidity Sensor Module with LED is a small humidity and temperature sensor that you can connect to your Arduino and get readings for temperature and humidity in the environment.
Features:
DHT11 sensor with PCB and LED indicator along with cable; 3 to 5V power and I/O, 4 pins with 0.1″ spacing
The board has pre-built 4.7K or 10K resistor, which you will need to use as a pull-up from the data pin to VCC.
2.5mA max current use during conversion (while requesting data)
Good for 20-80% humidity readings with 5% accuracy
Good for 0-50°C temperature readings ±2°C accuracy.
Package Includes:
1 x DHT11 Temperature And Humidity Sensor Module.
3 x Female to Female Connecting cable.
