Revan LOR-TH is a battery LoRaWAN environment node for cold rooms, pharma cabinets, greenhouses and building automation. On-board temperature/humidity (Sensirion SHT40 class), a 3-wire PT100 immersion probe input and a dry contact sit in one enclosure. No Ethernet or 4G modem on the node — EU868 Class A uplinks to a gateway. For short-range phone control use the BLE relay; for remote relay/web UI use the IP & 4G Smart Relay.
Cold-chain logistics, supermarket cabinets and freezers, vaccine fridges, smart greenhouses, HVAC and clean rooms. A door magnet or meter pulse is read on the dry contact. LoRaWAN 868 MHz, multi-year battery and an IP65/IP67 housing are chosen for unattended rooms.
The node sleeps in the microamp range, samples on a period and sends a Class A uplink. Join is OTAA or ABP. The PT100 is read on a precision ADC bridge (probe range typically −200°C to +600°C). Dry contact has 1 MΩ pull-up and TVS/ESD. Outdoor range is kilometres; indoors 500 m–2 km is typical.

| Battery | 1× 3.6 V Li-SOCl2; sleep < 2 µA; 5+ years |
| Housing | IP65/IP67, wall mount |
PT100 span depends on the probe. The board is not a 24 V loop supply. LoRaWAN coverage must be checked on site.
Mount the membrane away from standing water. Wire PT100 as 3-wire. Dry contact is for potential-free signals only. Keep join keys site-specific. This node is monitoring, not a legal cold-chain recorder or a safety SIL loop.
LOR-TH node, Li-SOCl2 holder and wall mount. External PT100 is specified on order.
LOR-TH measures climate/probe over LoRaWAN and does not drive a power relay. The IP & 4G unit is remote relay, web UI, SMS and MQTT.
No. The node is LoRaWAN; the site gateway may use Ethernet or cellular.
