ERS Eco is a LoRaWAN® temperature and humidity sensor for the indoor environment. This sensor is your environmentally friendly option, with an organic solar cell as the only power source and an enclosure made from biodegradable material. Removing batteries from a wireless IoT device significantly reduces the environmental impact and maintenance costs.

The ERS Eco can last up to 30 days in the dark depending on the sample interval, transmit interval, data rate, and environmental factors. It can be used with a self-adapting feature that will result in lower current consumption, lower network load, and less redundant data sent. With the feature activated, the sensor will adapt the transmission rate if the measured data is unchanged.
