Description ERS is a universal indoor climate sensor for LoRaWAN® wireless network. The sensor measures temperature, humidity, light intensity, and detects motion. ERS is a battery-powered device and is designed to be wall-mounted. The motion sensor can be used for presence monitoring systems. ERS is equipped with NFC (Near Field Communication) and can easily be configured from a smartphone. The barcode contains DevEUI and sensor type.
Main features of ERS • • • • • • • • • • • • • • • Compatible with LoRaWAN® specification 1.0.
Installation 1. Remove the back panel of the sensor with a small screwdriver. 2. Install the batteries. The ERS 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 performance and battery life. Use battery slot A if only one battery is used. Caution: Using batteries other than the ones provided may result in loss of performance and battery life, and also damage to the device.
3. Mount the back panel securely to the wall with at least 2 appropriate screws, using some of the six mounting holes. 4. Attach the sensor part to the back panel. Service and maintenance No serviceable parts inside. If service is needed other than battery replacement, please contact your distributor. 7 Elektroniksystem i Umeå AB Industrivägen 12, 90130 Umeå, Sweden E-mail: support@elsys.se ǀ Web: www.elsys.
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. All sensor settings can be locked from the server or NFC to make end-users unable to read or change settings on the sensor. NFC Configuration 1.
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. Application parameters All parameters for the “Sensor settings” application can be found in our settings document. Please visit the support section on our webpage for more information.
Sensor startup 1. 2. 3. 4. 5. When the sensor starts up, it loads configuration from the internal memory and merges it with user configuration. When the configuration is done, the sensor writes the new configuration to the NFC chip. The sensor always writes new configurations to the NFC chip when something changes in the sensor or if NFC data is corrupted by an NFC writer or phone. The sensor always writes the new configuration to NFC chip at startup.
Sampling mode / Periodic measurement The sensor makes periodic measurements according to the user configurations. Schedule Transmission The sensor transmits the data according to the user configurations. Note: The configured sending interval can be overridden by network limitations. Due to this, the spreading factor and sending interval settings might result in longer intervals than intended. 11 Elektroniksystem i Umeå AB Industrivägen 12, 90130 Umeå, Sweden E-mail: support@elsys.se ǀ Web: www.elsys.
Motion detection range Actual range of the sensor can be influenced by environmental conditions. Avoid installing the sensor in areas where it will face direct or reflected sunlight. Avoid installing near windows, air conditioning, or heating vents. Such placements will give false values. The PIR can cause self-trigger if sensors are placed too close to each other. Keep this in mind when you mount or test the sensors.
