ELT-2 measures temperature, humidity, and atmospheric pressure. It also detects acceleration.
ELT-2 has two multifunctional inputs (0...3 V, 0...10 V, 4...20 mA, digital) for external sensors. Alternatively, you can connect two switches to the inputs or set the multifunctional input in pulse counting mode.
Optional external sensors are available for temperature measurement, water leak detection, and soil moisture measurement. Optional modules include ADC Module for connecting Pt1000 sensors, EXT Module for controlling lighting, actuators and relays, and Step Up Module for boosting battery voltage to 5 V.
You can configure all settings via a smartphone application using an NFC-enabled smartphone or over the air via your LoRaWAN network. You can update the firmware with an optional firmware update tool.
This device is battery-operated and requires one 3.6 V lithium battery. Battery is not included. If you install an EXT Module to the device, you can connect an external power source to ELT-2 and use the device as class C or class A LoRaWAN device.
External antenna is sold separately.
