Core Features

Integrated temperature and humidity monitoring, a cost-effective solution. It features an integrated sensor module that simultaneously measures temperature and humidity, with a simple structure and controllable costs, making it an ideal choice for entry-level temperature and humidity monitoring.
Plug-in design, integrated for convenience. : Standard 4-pin straight‑in leads, enabling direct soldering onto the PCB without the need for additional adapters, thereby simplifying equipment integration and reducing development complexity and costs.
Blue engineering-plastic housing, balancing protection and heat dissipation. The housing is made of blue engineering plastic, offering excellent insulation and breathability. It effectively protects the sensor element from dust while ensuring adequate air circulation to maintain measurement accuracy.
Digital signal output, easy to use. : Built-in signal-processing circuitry delivers a direct single-wire digital output, eliminating the need for external A/D conversion and enabling seamless interfacing with microcontrollers or host control systems, thereby shortening the development cycle.

Typical application scenarios

Environmental monitoring of smart home devices (smart plugs, thermohygrometers, air purifiers)
Temperature and humidity sensing and control for small household appliances (dehumidifiers, humidifiers, and air-cooling fans)
