LoraWan, NB-IOT sensori

ERS Eco CO2 is a LoRaWAN® temperature, humidity, and CO2 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 CO2 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.

C02
Operating principle Non-dispersive infrared (NDIR)
Measurement range 400-5000 ppm; extended range up to 10000
ppm
Accuracy ± (30 ppm + 3% of reading)
Extended range ±10% of reading
Accuracy is achieved at 15-35°C, 0-80% RH after at least
three automatic baseline corrections have been performed
(24 days, three 8-day periods).
Calibration Automatic baseline calibration routine that will
set 400 ppm to the lowest measured value in
the last 8-day period.
The sensor can also be manually calibrated
