Temperature & Humidity Sensor DHT11

The DHT11 Temperature and Humidity Sensor is a temperature and humidity sensor that allows you to take temperature readings between 0 to 50º Celsius and humidity between 20 to 90%, widely used for Arduino projects.

DHT11 in practice detects humidity and temperature and sends this information to the microcontroller board, which must be programmed to perform some action when a certain temperature or humidity is reached.

The temperature sensing element is an NTC type thermistor and the humidity sensor is HR202 type, the internal circuit reads from the sensors and communicates to a microcontroller via a one-way serial signal.

Ideal for use by professionals or students in technological fields, the DHT11 Temperature and Humidity Sensor offers reliable and stable data.

You can develop various projects with the DHT11 Module and Arduino, such as turning on the air conditioner automatically when the room reaches a certain temperature or turning on the function to remove moisture when it reaches a certain humidity.
