Product Attributes

Introduction

This is a high-precision industrial-grade RS485 temperature and humidity sensor. It employs premium digital integrated sensing elements and reliable digital processing circuitry to convert ambient temperature and humidity into corresponding RS485 signals, enabling centralized monitoring in conjunction with host systems. The module features a wide measurement range, high detection accuracy, and fast response speed, supporting temperature detection from -40 to 120°C and humidity detection from 0 to 99.9% RH. The sensor is fully enclosed in an aluminum alloy housing that is waterproof and heat-resistant, making it suitable for harsh environments. In addition, the probe features a breathable, dust-proof design that effectively protects the internal PCB and extends service life. The product offers excellent long-term stability, low latency, high resistance to chemical contamination, and outstanding repeatability. It is an ideal solution for precise relative humidity and temperature measurement in HVAC applications.
