NFC

All our sensors are equipped with NFC (Near Field Communication) for easy configuration with an Android phone. With our application “Sensor Settings“, you can change sample rate, data rate, encryption keys, triggers, activation and much more. All parameters can also be changed over the air from the server.

LoRaWAN Certified

LoRa Technology is the DNA of IoT, connecting sensors to the Cloud and enabling real-time communication of data and analytics that can be utilized to enhance efficiency and productivity.

As a proud member of the LoRa Alliance, we ensure that all ELSYS sensors are LoRaWAN™ Certified.  All our sensors are built on the LoRaWAN™ stack from Semtech. Channel planes for US902-928, EU863-870, AS923, AU915-928, KR920-923.

NFC settings specification

Settings on all Elsys LoRa sensors are stored on the embedded NFC chip which is a NFC Forum Type 4 tag with a NDEF text entry. Use our Android application or any other NFC application to read and write settings from the sensors.

The settings use the following format:

{key1}:{value1}
{key2}:{value2}
...

See the table below for all possible settings:

ERS

Print

ERS and ERS-lite are LoRaWAN™  room sensors for measuring indoor environment. ERS is enclosed in an room sensor box and it is designed to be wall mounted. Inside the ERS you will find five internal sensors: temperature sensor, humidity sensor, light sensor, and a motion sensor (PIR). For ERS-CO2 there is an additional CO2 sensor, and for the ERS-sound there is an additional sound sensor for peak and average dBa level. ERS is powered by two 3,6V AA lithium battery (one for ERS-lite). The Battery life is estimated to be up to 10 years but depends on sample interval, transmit interval, data rate and environmental factors. You are welcome to use our online battery lifetime calculator. All Elsys sensors are equipped with NFC (Near Field Communication) for easy configuration with an Android phone. With our application “Sensor Settings“, you can change sample rate, data rate, encryption keys, triggers, activation and much more.  All our sensors are built on the LoRaWAN™ stack from Semtech.
