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. If more than 2 meters, for example 10 or 100 meters, probe can be connected to RS 485 Interface.
2 digital inputs (DI) supported, for example, status(on/off) monitoring of devices can be realized through this product. Eg: smoke detector and water leakage detector in data center can be connected to this device.
1 digital output(DO) relay out control supported. For instance, when the temperature exceeds the preset threshold, the air conditioner is activated.
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.

PoE allows the sensor to receive both operating power and network data through a single RJ45 Ethernet cable. This eliminates the need for localized AC outlets, simplifying installation and reducing wiring complexity.
Yes. The standard probe is 1-2 meters. For distances extending beyond 2 meters (such as 10 or 100 meters), the probe can be customized and connected to the device via the RS485 interface to ensure accurate signal transmission.
To facilitate seamless integration with third-party software and IoT platforms, the sensor natively supports multiple industrial and network protocols, including Modbus TCP, UDP, SNMP (V1/V2), and MQTT.
The device features 2 DI channels for status monitoring (e.g., connecting smoke or water leakage detectors) and 1 DO relay output channel to trigger external hardware controls, such as turning on an air conditioner when temperature limits are exceeded.
The sensor provides instant alerts via localized sound and light indicators on the device, as well as remote notifications via email, SNMP Trap, or platform push alerts to keep you informed immediately.
The sensor is equipped with massive local storage capable of recording up to 100,000 data points, ensuring continuous data logs even during temporary network interruptions.
