Page 5: Description
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. -

Page 8: Mounting Guidelines
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). -
Page 9: Installation
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. -
Page 10: Service And Maintenance
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 5.2 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” application can be found in our settings document. -
Page 13: Sensor Behavior
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. 2. When the configuration is done the sensor tries to join the network if OTAA (Over the Air Activation) is enabled. -

Page 19: Room Occupancy (Ers2 Eye)
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. -
Page 20: Sound Level
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. -
