The Aitrip DHT11 module consists of a 3-pin PCB breakout featuring an AOSONG resistive-type humidity sensor and an NTC thermistor. Technical documentation lists a built-in 10k pull-up resistor to facilitate direct integration with 5V and 3.3V logic systems. Performance metrics show a humidity accuracy of ±5% RH and a temperature accuracy of ±2°C, with a maximum sampling frequency of 0.5Hz.
The structural design includes a pre-soldered capacitor and resistor to simplify wiring for hobbyist applications. Material constraints indicate that the resistive film is susceptible to contamination in high-humidity or chemically active environments, which may lead to permanent calibration drift. Data transmission is handled via a single-bus digital signal.
The 5-Pack DHT11 Digital Temperature & Humidity Sensors provides a similar technical profile in a bulk format for larger-scale educational deployments.
This module serves as a foundational component in the DIY digital sensor category.
