This module utilizes the Aosong DHT11 digital temperature and humidity sensor, which is a compound sensor integrating both calibrated digital signals for temperature and humidity output. It employs specialized digital module acquisition technology alongside temperature and humidity sensing technology, ensuring reliable stability, fast response time, and robust anti-interference capabilities for the product. The sensor comprises a polymeric resistive humidity-sensing element and an NTC (Negative Temperature Coefficient) temperature-measuring element, connected to a high-performance 8-bit microcontroller. Communication between this microcontroller and the microprocessor is facilitated through a single bus, requiring only a single wire for data transmission, thereby simplifying the integration process and reducing wiring complexity.
