ELT External Temperature and Humidity Sensor LoRa The ELT External Temperature and Humidity Sensor LoRais a wireless sensor designed for applications where reliable outdoor humidity measurements are essential. The ELT Outdoor Temperature and Humidity LoRa (ELT-ETH-L) is a wireless LoRaWAN® sensor designed for applications where reliable outdoor humidity measurements are essential. With its external temperature and humidity sensor, it is ideal for outdoor environmental monitoring. Since the temperature and humidity sensor is mounted outside the housing, the ELT-ETH-L measures the ambient air directly, providing reliable humidity monitoring and accurate measurements of the ambient temperature. Thanks to its long battery life (up to 10 years), the ELT-ETH-L requires minimal maintenance, and the batteries can be easily replaced as needed. The sensor’s configuration-including sampling rate, data rate, encryption key, triggers, activation, and more-can be easily set via NFC using a smartphone or via the LoRaWAN® downlink. Note: Antennas and batteries are not included. This product requires 1 x AA 3.6-V lithium battery (ER14505). (See accessories)
