DHT11 Temperature and Humidity Module Style:Sensor Temperature Range: 0℃ - 55℃

Temperature Range: 0℃ - 55℃

it has integrated MCU

As a result

It is upgraded version of TowerPro MG945 with the new PCB and IC control system which makes it  more accurate

Since this chip is a special bidirectional level change

DHT11 Temperature and Humidity Module Style:Sensor Temperature Range: 0℃ - 55℃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
