Temperature and Humidity DHT11 Sensor

Do you need a small yet accurate temperature and humidity sensor? This sensor could give you a temperature reading with an accuracy of +-1°C.

This sensor could operate with a 3.3V to 5V power supply. The operating current is 0.3mA when on use and 60µA on stand-by mode. The temperature range this sensor can detect ranges from 0°C to 50°C, and the humidity it can sense is from 20% to 90%.

You could interface this to your Arduino using one Digital pin, and  2 for the power supply (VCC/GND).

You need a pull-up resistor between the data and 5V to accurate readings.

You could use this with small scale temperature and humidity monitoring projects.

We recommend the DHT22 sensor for a broader temperature range.
