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.
