ERS is equipped with four internal sensors for measuring temperature, humidity, light, and motion (PIR sensor). The motion detector can be used for presence monitor systems and is ideal for workplace management. 

This sensor is also has a traffic light feature to let you know when a certain threshold of the temperature, or any other value, has been reached. The threshold value is configurable and you can choose the color of the light, the frequency, and the light intensity.

ERS is a smart and professional LoRaWAN® sensor for indoor climate measurements. It has a clean and modern design which makes it discrete in both business and home environments. ERS can measure temperature, humidity, light, and room activity. The sensor is highly configurable, and the user can change all parameters as they like. ERS works great as a sensor for smart building, dynamic workspaces, or climate control. 

The battery life is estimated to be up to 10 years but depends on sample interval, transmit interval, data rate, and environmental factors. It is powered by two 3,6V AA lithium batteries.

All our sensors are equipped with NFC (Near Field Communication) for easy configuration with an Android phone. You can change the sample rate, data rate, encryption keys, triggers, activation, and much more in our application “Sensor Settings“.  All our sensors are built on the LoRaWAN® stack from Semtech.

Channel plans for US 902-928, EU 863-870, AS 923, AU 915-928, and KR 920-923.
