High Precision Lora Battery Temp Humidity Data Logger for Drug Cold Storage

Renke's in-house spread spectrum technology delivers strong signal penetration and a maximum communication distance of 3000m in open, unobstructed outdoor areas without repeaters.

Strong indoor penetration capability allows reliable wireless transmission through multiple reinforced concrete walls, eliminating wiring runs through corridors, floors, or sealed cold storage rooms.

Built-in frequency hopping improves resistance to electromagnetic interference, maintaining stable communication in complex industrial environments.

Wireless transmission removes the cabling complexity of wired systems, where a single device failure can disrupt communication across the entire network and complicate troubleshooting.

Lineup spans standard -40C to 80C models down to -200C cryogenic and up to 300C high-temperature variants, all sharing the same LoRa wireless transmission platform.

If wireless communication is interrupted, the logger automatically stores data locally and uploads all accumulated records once the connection to the host or gateway is restored.

Choose internal rechargeable battery operation for up to 8 months per charge, or external 220V AC power for permanent installations requiring continuous uninterrupted operation.

Default 120-second upload interval can be adjusted down to a 40-second minimum, balancing data resolution against battery life for different monitoring precision requirements.

Device parameters are configured via Bluetooth connection, eliminating the need for a wired connection to a PC during initial setup, address assignment, or threshold configuration.

Works with RS-LGH-100, 200, 300, and 400 series gateways, with the largest model supporting up to 128 sensors for large-scale multi-point deployment in a single network.
