Core Features

Integrated temperature and humidity monitoring, with high accuracy and stability. : Equipped with a high-precision temperature and humidity sensor, it can simultaneously measure both temperature and humidity. Featuring excellent linearity, high repeatability, and minimal temperature drift, it ensures long-term stable performance, meeting the stringent accuracy requirements of various devices for environmental temperature and humidity data.
Plug-in design, integrated for convenience. Standard 4-pin straight-through pins can be directly soldered onto the PCB, eliminating the need for additional adapters, thereby simplifying the device integration process and reducing development costs.
Black engineering plastic housing with excellent protection. The housing is made of black engineering plastic, offering excellent insulation, electromagnetic interference resistance, and breathability. It effectively protects the sensor element from dust while ensuring adequate air circulation to maintain measurement accuracy.
Low-power digital output, easy to use. : Built-in signal-processing circuitry delivers a digital output (either on a single-wire bus or via I2C), eliminating the need for an external ADC and enabling direct interfacing with a microcontroller or host system, thereby shortening the development cycle.

Typical application scenarios

Temperature and humidity monitoring and environmental control for industrial control equipment, power cabinets, and communication base stations.
Temperature and humidity monitoring and operational control for HVAC systems, dehumidifiers, and fresh-air ventilation systems
