The wireless temperature sensor TP-304-LoRa is designed to measure air temperature. TP-304-LoRa sensors transmit information via the LoRa protocol to a wireless LoRa interface converter. The application area of air temperature sensors is very broad and includes: Maintaining the microclimate within specified limits in production facilities equipped with humidity-sensitive electronic devices; Monitoring humidity indicators in office premises, domestic environments; In the utility sector — in boiler rooms and water treatment plants to prevent condensation; Periodic control helps prevent the appearance of mold and mildew on building walls or warehouses; Control of technological processes; Monitoring environmental parameters, and more. The modulation method LoRa (Long Range) provides significantly greater communication range compared to other competing methods. It also has resistance to external interference and noise, enabling its use across various industrial sectors. The wireless temperature sensor TP-304-LoRa is housed in an ABS plastic case and is intended for wall mounting. It is recommended to install TP-304-LoRa sensors with a protective cover over the sensitive element facing downward, which minimizes sensor damage in high humidity and near the dew point. The sensor is mounted so that air can freely circulate around it. When choosing a location on the wall, avoid drafts, direct sunlight, and other heat sources. Installation is carried out directly on the wall.
