# CJDHT11 Digital Temperature and Humidity Sensor Kit
High-Precision Resistive Sensing Module for DIY Electronics, IoT Development & Multi-Scenario Environmental Monitoring
## Core Advantages
1. Equipped with premium resistive humidity sensing element and high-precision NTC temperature measurement component, it captures environmental data with ultra-low error margin, delivers reliable, consistent temperature and humidity readings without requiring frequent calibration.
2. Optimized single-wire protocol circuit design on flame-retardant PCB board only occupies 1 I/O port for data transmission, greatly reducing circuit wiring complexity and saving resources for your microcontroller system.
3. High-strength ABS plastic outer shell with porous grid design accelerates air contact with internal sensing elements, while protecting core components from dust and minor collisions, extending service life and shortening response speed to environmental changes.
4. Gold-plated copper pins and optional customizable-length copper core cable make it compatible with almost all common development boards including Raspberry Pi and STM32, perfectly adapting to different installation demands for various scenarios.
5. Built-in signal filtering circuit and high-quality SMD electronic components effectively suppress electromagnetic interference from surrounding environments, maintain stable data output even in complex electrical working conditions and avoid unexpected data deviation.
6. Safety compliance: Manufactured in Mainland China, this sensor module contains no high-concerned chemicals, ensuring safe handling and compliance with standard environmental and safety guidelines.
