LHT65N-DC LoRaWAN Open/Close Potential-free Contact 868MHz

The LHT65N-DC from Dragino is a long-range LoRaWAN sensor that detects the status of potential-free contacts, as well as the state of open or closed contacts, and sends this data to an IoT server via the LoRaWAN network. This sensor has a built-in temperature and humidity sensor and a 3-wire connection (VCC/GND/INT) for potential-free contacts. The LHT65 has an integrated non-rechargeable CR17450 2400mAh battery which, depending on the number of transmissions, lasts for up to 10 years (more information in the operating instructions). The LHT65N-DC is fully compatible with the LoRaWAN v1.0.3 Class A protocol and can be operated with a standard LoRaWAN gateway. Each sensor is preloaded with a set of unique keys for LoRaWAN registrations. These keys are registered on the local LoRaWAN server and the sensor automatically establishes a connection when switched on, provided network coverage is available.

Recommended Accessories:

• Magnetic Door Window Contact Metal
• Lora Gateway

Features:

• Long-Range LoRaWAN sensor: The LHT65N-DC provides a particularly high range and reliable communication.
• Potential-free contact status: Detects the status of open or closed contacts.
• Integrated temperature and humidity sensor: Precisely measures the ambient temperature and humidity.
• Energy saving: With a built-in battery that lasts up to 10 years, the sensor is very energy efficient.
• Data storage: Supports data storage in the absence of network coverage and sends the data as soon as the network is available again.
• Open Alarm Feature: Allows the setup of alarms that trigger an immediate notification when opened.
• Compatibility: Fully compatible with the LoRaWAN v1.0.3 Class A protocol.
• Easy to install: Thanks to the compact design and easy installation, the sensor is quickly ready for use.

Application Examples:

• Door and window monitoring: Monitor the status of doors and windows in a building.
• Industrial machine monitoring: Monitor the condition of machines and plants to avoid unplanned downtime.
• Environmental monitoring: Capturing the temperature and humidity in warehouses or cooling rooms.
• Security applications: Monitor doors and gates in security-critical areas.
• Agriculture: Monitoring of gate entrances and access points on agricultural farms.
