Description
The DHT11 Temperature and Humidity Sensor Module is a versatile electronic module designed for measuring temperature and humidity in various environments. It utilizes the DHT11 sensor, known for its accuracy and reliability, to provide real-time temperature and humidity readings. The DHT11 humidity and temperature sensor produces a calibrated digital output.
This module features a digital output, making integrating it into microcontrollers or other digital devices easy. It eliminates additional analog-to-digital conversion circuitry, simplifying the setup process. This is a low-cost humidity and temperature sensor that offers excellent reliability and long-term stability. Moreover, the board has a high-performance 8-bit microprocessor that is linked to the DHT11 sensor module. The DHT11’s output is a digital signal on a single data pin. The sensor update frequency must be monitored every two seconds (0.5Hz).
A built-in LED, a bypass capacitor between Vcc and Gnd, and a pull-up resistor between the data line and Vcc are further features of the board. This sensor has a wide temperature measurement range of 0°C to 50°C with a ±2°C accuracy, allowing for precise temperature monitoring. It also measures relative humidity in the range of 20% to 90% with a ±5% accuracy, providing valuable humidity data.
