Product Description : 

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 when using our library, sensor readings can be up to 2 seconds old.

Features :

  • Low cost, 2.5mA max current use during conversion (while requesting data)
  • 3 to 5V power and I/O, Body size 15.5mm x 12mm x 5.5mm
  • Good for 20-80% humidity readings with 5% accuracy
  • Good for 0-50°C temperature readings ±2°C accuracy
  • No more than 1 Hz sampling rate (once every second), 4 pins with Approximate 0.1" spacing

Specifications :

  • Voltage: 3 to 5V power
  • Temperature readings: ±2°C
  • Current max: 2.5mA
  • Item Weight: ‎10 g

Compared to the DHT22, this sensor is less precise, less accurate and works in a smaller range of temperature or humidity, but its smaller and less expensive.

Comes with a 4.7K or 10K resistor, which you will want to use as a pull-up from the data pin to VCC.
