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 greatly simplifies installation, especially 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.

This web sensor is capable of monitoring temperature, relative humidity, dew point, and atmospheric pressure simultaneously, making it ideal for cleanrooms, laboratories, and operating rooms.
Yes, it supports standard PoE (802.3af) power supply, allowing data and power transmission through a single Ethernet cable. A standard DC 12-48V backup power interface is also reserved.
It supports a wide range of industrial and network protocols, including Modbus TCP, UDP, SNMP (V1/V2), and MQTT, ensuring easy integration with your existing LAN or IoT systems.
The device features built-in memory that stores up to 100,000 data records cyclically. This allows for historical data tracing and analysis directly from the device without losing data during network outages.
Yes, the sensor provides 2-channel digital inputs (DI) for dry contacts (like door magnets or water leak sensors), 1-channel RS485 to Ethernet conversion for Modbus RTU devices, and 1-channel relay output (DO) for automated device control.
The sensor supports high/low threshold settings for all monitored parameters. When thresholds are exceeded, it can trigger local sound and light alarms, send email notifications, or transmit SNMP traps.
