["The ELSYS opening activity sensor is only slightly larger than the AA lithium battery inside. This small size and subtle design make it ideal for indoor use. It can of course be used to detect door openings and closings, but it can also be mounted on window panes or cupboards. Because not only the opening but also the acceleration is recorded, this sensor is more versatile in use, for example in smart offices or smart buildings. The necessary 3.6V AA lithium battery is not included and must be ordered separately", "LoRaWAN® certification in progress", "Accelerometer", "Door switch", "NFC for configuration", "Configuration over the air", "Smart buildings", "Management of workplaces", "Door activity detection", "Detection of movements", "Frequency: EU 868 MHz", "Transmission power: 14 dBm", "Operating temperature: 0° - 40° C", "Configuration: via download link or NFC", "Operating life: up to 10 years", "Operating humidity: 0% - 85% (non-condensing)", "LoRaWAN: 1.0.3, Class A or C", "Power supply: 1 x 3.6 V AA lithium battery (replaceable) - battery not included!", "Activation: OTAA or ABP", "Measured variables: door contact and acceleration"]
