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 like ceilings. A standard DC power interface is reserved as backup.
Local Data Logging: 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 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.

Q1: Which environmental parameters can this web sensor monitor?
A: It monitors temperature, humidity, dew point, and atmospheric pressure. This makes it ideal for operating rooms, cleanrooms, and laboratories.
Q2: Does the device support Power over Ethernet (PoE)?
A: Yes, it supports PoE (802.3af) power supply via an Ethernet cable, simplifying installation. It also reserves a standard DC 12-48V power interface as backup.
Q3: How many data logs can be stored locally on the device?
A: The device features built-in memory capable of storing up to 100,000 data records, enabling cyclical recording of historical data for easy tracing and analysis.
Q4: What integration protocols and interfaces are supported?
A: It communicates via an RJ45 Ethernet interface and supports Modbus TCP, UDP, SNMP (V1/V2), and MQTT protocols. It also includes 1 channel RS485 for protocol conversion.
Q5: Can the device trigger alarms and control external equipment?
A: Yes, it features 2 Digital Inputs (DI) for monitoring external sensors and 1 Relay Output (DO) for automatic control. Alarms can be triggered via sound/light, email, or SNMP traps.
Q6: What is the operating temperature range and measurement accuracy?
A: It operates reliably from -25°C to 65°C. The measurement accuracy is ±0.2℃ for temperature, ±2%RH for humidity, and ±0.12 hPa for atmospheric pressure.
