ESM 5k

ESM5k is a small  LoRaWAN™  sensor enclosed in a small ABS box (60x35x20mm). Inside the ESM5k you will find four/five internal sensors: temperature sensor, humidity sensor, light sensor and an accelerometer. It can also be fitted with a PIR motion sensor (MOQ=100). ESM5k is powered by 3,6V 1/2 AA lithium battery. 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.

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.

Battery life calculator

Chose sensor (ERS,ELT-1, ESM5k) and data coding(SF7-SF12).  Fill in number of samples per hour. Use “All sensors” field to change all time settings at once.

*Receive window2 (SF9) depends on server settings .

** Battery life is a theoretical value. Battery life is negatively affected by moister, high temperature, dirt, vibration and more. Most battery manufacturer grantees maximum 10 years of battery life (storage and usage).

ELT-1/ELT-2-HP

ELT-1 and ELT-2-HP are general LoRaWAN™ devices for measuring analogue or digital signals. ELT-1/ELT-2-HP can for example be used together with electricity meters, flow meters, analogue sensors, moisture sensors, temperature sensors, water leak cable or ultrasonic distance sensors. They are enclosed in an IP65 box and are designed to be outside. Inside the ELT-1/ELT-2-HP you will find three internal sensors: a temperature sensor, a humidity sensor and an accelerometer for orientation measurements. On the ELT-2-HP you will also find an additional atmospheric pressure sensor. They are powered by a 3,6V AA lithium battery. The Battery life is estimated to be up to 10 years but depends on sample interval, transmit interval, data rate, power output 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 of our sensors are built on the LoRaWAN™ stack from Semtech.
