DHT11 Temperature and Humidity Sensor Module - for Arduino Raspberry STM (DHT11 with PCB & LED)

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 spits out a digital signal on the data pin (no analog input pins needed). Its fairly simple to use, but requires careful timing to grab data. The only real downside of this sensor is you can only get new data from it once every 2 seconds, so in your code please use sensor reading interval at 2 seconds or more.

• Model: DHT11 Temperature and Humidity sensor with PCB and LED indicators 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
