YCLH Sensor
1 / 4
Air Pressure + temperature + humidity: Primarily used in environments with high cleanliness requirements, such as operating rooms, clean workshops, cleanrooms, and laboratories.
2-channel digital input (DI): Accepts dry contact signals for monitoring the status of devices such as door magnets, water leak sensors.
1-channel RS485 to Ethernet: Acts as a protocol conversion gateway, using devices such as Modbus RTUs (e.g., electricity meters, water meters, traditional sensors) to Ethernet for system integration.
1-channel relay output (DO): Functions normally open (NO) / normally closed (NC) contacts for programmable control of external devices. Automatically and intelligently activates/deactivates devices such as fans, alarms, or lights based on threshold violations.
Ethernet Communication: 10/100M auto-adaptive Ethernet interface, supporting multiple network protocols including MQTT, SNMP, Modbus TCP, and UDP, facilitating integration into existing LANs.
PoE Power (802.3af): Supports power supply via Ethernet cable, eliminating the need for separate power wiring. This simplifies installation in challenging locations such as ceilings or confined spaces. A standard DC power interface is reserved as a backup.
Local Data Logging: The device has built-in memory capable of storing 100,000 data records, enabling cyclical recording of historical data for easy tracing and analysis.
Multiple Alarm Mechanisms: Allows users to independently set high/low alarm thresholds for each monitored parameter. Supports various alarm methods, including local sound/light indicators, email notifications, or SNMP traps.
Wide Temperature and Voltage Range Design: Reliably operates over a wide temperature range of -20 °C to 65 °C and in complex industrial electromagnetic environments.
Rugged Housing: Constructed from a metal or high-strength flame-retardant plastic housing, providing superior shielding and durability.

The sensor monitors temperature, relative humidity, dew point, and atmospheric pressure, making it ideal for cleanrooms, laboratories, and operating theaters.
Yes, it supports standard Power over Ethernet (PoE 802.3af), allowing power and data transmission over a single RJ45 cable. A backup DC 12-48V power interface is also reserved.
The device supports standard protocols including Modbus TCP, UDP, SNMP (V1/V2), and MQTT via its RJ45 Ethernet interface for seamless network integration.
Yes, it features a 1-channel relay output (DO) with normally open/closed contacts that can automatically control external devices like fans, lights, or alarms based on threshold violations.
The device features built-in memory capable of locally logging up to 100,000 data records cyclically for historical tracing and analysis.
It supports multiple alarm mechanisms, including local sound and light alerts, email notifications, and SNMP traps when monitored parameters exceed set thresholds.
