["ELSYS ERS Eco temperature, humidity and CO2 sensor The ERS Eco CO2 is a LoRaWAN® temperature, humidity and CO2 sensor for indoor spaces. This sensor is an environmentally friendly alternative with an organic solar cell as the only power supply and a housing made of biodegradable material. Eliminating batteries in a wireless IoT device significantly reduces environmental impact and maintenance costs. The ERS Eco CO2 can work in the dark for up to 30 days. This time depends on the following factors: measurement interval, transmission interval, data rate and environmental factors. The sensor can operate in a self-adaptive mode resulting in less power consumption, less network load and less redundant data. If you activate this function, the sensor will adjust the transmission rate if the measured values ​​have not changed. All ELSYS sensors have a Scandinavian design that integrates beautifully into all possible applications and have an NFC interface for easy configuration via an Android app", "Measurement of temperature, humidity and CO2", "Powered by an organic solar cell", "Housing made of biodegradable material", "Wireless and without batteries", "Up to 30 days operation in the dark", "Self-adjustment mode", "Measuring the indoor environment", "Smart buildings"]
