The DHT11 module integrates a calibrated capacitive humidity sensor and a thermistor to deliver stable digital readings for ambient air conditions. It communicates via a proprietary single-bus protocol, requiring precise timing but eliminating the need for analog-to-digital conversion on the host controller.
Designed for basic environmental monitoring, the sensor offers a cost-effective solution with moderate accuracy suitable for non-critical applications. Its compact PCB includes a power indicator LED, a decoupling capacitor, and a pull-up resistor, making it ready for direct connection to development boards.
