DHT11 Sensor – Humidity and Temperature Sensor

Description

DHT11 Sensor is an exceptional device renowned for its ability to accurately measure both humidity and temperature. With its reliable performance, affordability, and versatility, it has become a popular choice across a wide range of applications.

DHT11 Sensor With PCB 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). It is 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.

One of the key features of the DHT11 Sensor is its accuracy. It provides precise readings for both humidity and temperature, ensuring that the collected data is reliable and trustworthy. Whether you are monitoring the humidity levels in a greenhouse, controlling the temperature in a smart home, or conducting scientific experiments, the DHT11 Sensor delivers consistent and accurate measurements.
