YCLH Sensor
1 / 5
Supports Power over Ethernet (PoE), delivering both power and data through a single cable.
Temperature accuracy ±0.2°C, humidity accuracy ±2%RH, providing reliable measurement results.
Probe is optional, usually 1-2 meters. For extended distances such as 10 or 100 meters, probes can be connected via the RS485 Interface.
Supports 2 digital inputs (DI) for monitoring device status (on/off), such as smoke detectors or water leakage detectors. Supports 1 digital output (DO) relay control to trigger external systems like air conditioners when thresholds are exceeded.
Built on wired Ethernet, immune to wireless signal obstruction and interference, ensuring zero packet loss and rapid response.
Supports multiple network protocols including MODBUS TCP, UDP, SNMP, and MQTT for seamless integration with third-party platforms.
Robust housing suitable for various industrial and commercial environments.
Immediate notifications via email, SNMP Trap, or platform push when data exceeds thresholds.
Capable of recording 100,000 data points.

Q1: Does this sensor support Power over Ethernet (PoE)?
A1: Yes, the device supports Power over Ethernet (PoE), allowing you to deliver both power and network data through a single RJ45 Ethernet cable. It also supports standard DC 12-48V power input.
Q2: What is the measurement accuracy of the temperature and humidity probe?
A2: The device features industrial-grade accuracy: temperature accuracy is ±0.2°C (at 25°C), humidity accuracy is ±2%RH (at 25°C), and atmospheric pressure accuracy is ±0.12 hPa.
Q3: Can the sensor probe be extended or customized?
A3: Yes. The standard probe is 1-2 meters. If you need a longer distance, such as 10 or 100 meters, the probe can be customized and connected directly to the device's RS485 interface.
Q4: What integration protocols are supported for third-party platforms?
A4: The sensor supports multiple standard communication protocols, including Modbus TCP, UDP, SNMP (V1/V2), and MQTT, ensuring seamless integration with various monitoring software and IoT platforms.
Q5: How does the device handle alert notifications when thresholds are exceeded?
A5: It features an intelligent alert system that supports local sound and light alarms, as well as remote notifications via email, SNMP Trap, or MQTT/platform pushes.
Q6: Does the device have internal data logging capabilities?
A6: Yes, the sensor includes massive local storage capable of recording up to 100,000 historical data points, preventing data loss in case of network interruptions.
