["ERS VOC can measure almost everything that concerns the indoor climate. You have full control over the air quality, temperature, light and humidity in your home or workplace. This is a smart and professional LoRaWAN® device and very easy to configure. Its design is minimalist, which makes it ideal for mounting on walls in any area. Battery life is estimated to be up to 5 years, but depends on sampling interval, transmission interval, data rate and environmental factors. It is powered by two 3.6V AA lithium batteries. These are not included in the scope of delivery! 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 key, trigger, activation and much more in our Sensor Settings application.
