YCLH Sensor
1 / 5
to monitor CO buildup and general air pollution.
for combined air quality and safety monitoring.
to detect gas leaks and pollutants from cooking.
to protect the health and safety of vulnerable residents.
Utilizes high-precision digital sensors to monitor ambient temperature and humidity in real-time, providing data for comfort, energy savings, and equipment safety.
Equipped with a highly sensitive solid-state electrochemical sensor to accurately detect carbon monoxide concentration levels. It provides effective early warning of potential safety hazards, serving as a critical safeguard for indoor safety and protection.
Comprehensively monitors various Volatile Organic Compounds (TVOC) to fully assess indoor air pollution levels, safeguarding occupant health and productivity.
Accepts dry contact signals for monitoring the status of devices like door magnets, water leak sensors, and differential pressure switches, expanding security and equipment monitoring capabilities.
Acts as a protocol conversion gateway, easily integrating third-party devices using protocols like Modbus RTU (e.g., electricity meters, water meters, legacy sensors) into the Ethernet network for system integration.
Features Normally Open (NO) / Normally Closed (NC) contacts for programmable control of external devices. Enables automatic smart activation/deactivation of equipment like fans, alarms, or lights based on threshold violations.
10/100M auto-adaptive Ethernet interface supporting multiple network protocols including MQTT, SNMP, Modbus TCP, and UDP for easy integration into existing LANs.
Supports power delivery over the Ethernet cable, eliminating the need for separate power wiring. This greatly simplifies installation, especially in challenging locations like ceilings or tight spaces. A standard DC power interface is retained as a backup.
The device features built-in memory capable of storing 100,000 data records, enabling cyclic logging of historical data for easy traceability and analysis.
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.
Operates reliably across a broad temperature range of -20°C to 65°C and in complex industrial electromagnetic environments.
Constructed with metal or high-strength flame-retardant plastic housing, offering excellent shielding and durability.

The sensor monitors Temperature, Humidity, Carbon Monoxide (CO), Indoor Air Quality (IAQ/TVOC), and calculates the Dew Point in real-time.
Yes, it supports standard PoE (802.3af) power supply, allowing data and power transmission over a single Ethernet cable. It also retains a standard DC 12-48V input interface as a backup power source.
The device features an RJ45 interface and supports multiple industrial and IoT protocols, including Modbus TCP, UDP, SNMP (V1/V2), and MQTT for seamless system integration.
It serves as an RS485-to-Ethernet protocol conversion gateway, allowing you to connect legacy Modbus RTU serial devices (like smart meters or external sensors) directly into your Ethernet network.
Yes. It has a built-in 1-channel Relay Output (DO) with NO/NC contacts. You can program it to automatically trigger external devices like ventilation fans, warning lights, or sirens when monitored thresholds are exceeded.
The sensor has built-in memory that stores up to 100,000 data records locally. For alerts, it supports local sound and light indicators, email notifications, and protocol-based alerts like SNMP Traps.
