DHT11 Humidity & Temperature Sensor

Overview

This is a multifunctional sensor that gives you temperature and relative humidity information at the same time. It utilizes a DHT11 sensor that can meet measurement needs of general purposes. It provides reliable readings when environment humidity condition in between 20% RH and 90% RH, and temperature condition in between 0°C and 50°C, covering needs in most home and daily applications that don't contain extreme conditions. Pin Configuration: DHT 11 has total 4 pins and their configuration is given below as:

1. VCC
2. DATA
3. NC
4. GND

Specifications: DTH11 possess the following features:
