Product Features:

  • A basic, 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).
  • Simply connect the first pin on the left to 3-5V power, the second pin to your data input pin and the right most pin to ground. Although it uses a single-wire to send data it is not Dallas One Wire compatible! If you want multiple sensors, each one must have its own data pin.
  • Compared to the DHT11, this sensor is more precise, more accurate and works in a bigger range of temperature/humidity, but its larger and more expensive.
  • Comes with a 4.7K – 10K resistor, which you will want to use as a pullup from the data pin to VCC.

Product Specifications:

  • Temperature Range: 5~95%RH
  • humidity Range: 95(RH)
  • Accuracy: ±2%RH
  • Size: 25.3 x 7.8 x 15.4cm
