Operating manual ERS2 series Important safety information Read this manual before attempting to install the device! Failure to observe recommendations included in this manual may be dangerous or cause a violation of the law. The manufacturer, ElektronikSystem i Umeå AB will not be held responsible for any loss or damage resulting from not following the instructions of this operating manual.
Operating manual ERS2 series 1. Description The ERS2 series of sensors are universal LoRaWAN indoor climate sensors. ® The sensor measures, depending on model, temperature, humidity, light intensity, CO2-level, sound-level, volatile organic compounds (VOC), occupancy and detects motion. ERS2 is a battery-powered device and is designed to be wall-mounted.
Operating manual ERS2 series 1.2 Label At the back of your device there is a label with an Aztec barcode containing DevEUI and sensor type. ElektronikSystem i Umeå AB Tvistevägen 48C, 90736 Umeå, Sweden E-mail: support@elsys.se ǀ Web: www.elsys.se...

Operating manual ERS2 series 2. Mounting guidelines Common mounting guidelines for ERS2 line of sensors: • Place the sensor in an open space on the wall, with an installation height of 1.6 meters (does not apply to ERS2 Eye, see 4.2).
Operating manual ERS2 series 3. Installation 1. Remove the back panel of the sensor by gently prying the tab with a small screwdriver. 2. Install the batteries. The ERS2 requires one or two AA batteries. The battery type is 3.6V Lithium Battery (ER14505). You can use one battery, but it’s recommended that you use two for best battery life.
Operating manual ERS2 series 3. Mount the back panel securely to the wall with at least 2 appropriate screws, using some of the four mounting holes. Alternatively, attach the sensor with double sided adhesive tape. 4. Attach the sensor part by hinging it on the back panel.
Operating manual ERS2 series 5. Sensor configuration All sensor settings can be configured via a smartphone application with NFC (Near Field Communication) or over the air via the network server and downlink data to the sensor. The sampling rate, spreading factor, encryption keys, port, and modes can be changed.
Operating manual ERS2 series 5.2 Over the air configuration All settings may be configured over the air via your LoRaWAN infrastructure. ® Please visit the support section on our webpage for more information regarding downlink protocol. 5.3 Application parameters All parameters for the “Sensor settings”...
Operating manual ERS2 series 6. Sensor behavior 6.1 Sensor startup 1. When the sensor starts up it loads any configuration parameters written to the NFC chip. The sensor will then write all configuration parameters back to the NFC chip.

Operating manual ERS2 series 7.6 Room occupancy (ERS2 Eye) The room occupancy algorithm uses both the PIR sensor and an 8x8 pixel heat map sensor. If the PIR triggers, occupancy is detected. If the PIR doesn’t trigger, the heat map is enabled, and its pattern is compared to a filtered mean value of the room.
Operating manual ERS2 series 7.7 Sound level The sound level sensor continuously measures the average and peak sound pressure level with no missing events. The analog part is always on, with a peak- hold circuit for peak level, and a mean-value filtering for average value. The digital part wakes and samples both signals every 10 s and does the final calculation before sending the data at the desired send interval.
