Overview

Digital temperature and humidity sensor for duct provides reliable monitoring for poultry environments. It measures humidity from 0-100%RH and temperature from -40°C to +80°C with multiple outputs (RS485, 4-20mA, 0-5V, 0-10V). The humidity sensor ensures stable performance with EMC anti-interference components and an industrial-grade chip. It features a clear LCD display, dual AC/DC power supply, and easy parameter setup via 485 configuration software. A silicone sealing ring, adjustable flange, and three-proof circuit board enhance durability and accuracy, while the screwless terminal design makes installation fast and convenient.

FAQ

Q1: What should be done if the readings fluctuate abnormally? ❯

Check for unstable power supply, poor grounding, or excessive electromagnetic interference. If using RS485, verify that the communication address and baud rate are configured correctly.

Q2: How to handle condensation or moisture accumulation on the probe? ❯

If condensation occurs, allow the sensor to dry naturally in a well-ventilated area. Avoid wiping or using heat sources to prevent damage to the sensing element.

Q3: Can the sensor be used in cold storage or refrigeration rooms? ❯

Yes. The wide operating temperature range (-40°C to +80°C) makes it suitable for cold storage, refrigeration monitoring, and other low-temperature environments.
