It takes only a few minutes to set up your EL-IOT-CO2, and you can configure your own high and low alarms for each measured parameter. If one of your set levels is breached an instant alarm is activated on the device, and notification options include email and SMS messages to your chosen contacts. 

The display shows current, maximum and minimum readings for carbon dioxide, temperature and humidity, as well as alarm and device status. 

The EL-IOT-CO2 runs from a USB power supply (supplied with the product) and can use AA batteries to provide a short-term backup if the power supply is interrupted. It is also provided with a wall mountable bracket for easy installation.

The high-contrast LCD shows current, maximum and minimum readings, as well as alarm and logger status: 

• On startup, the LCD runs through a test sequence in which all elements are activated, the alarm LEDs light up and the sounder beeps. • The CO2 sensor may take a few minutes to self-calibrate after startup, before readings are given. During this time keep in fresh air.

To maintain the accuracy of your EL-IOT-CO2, there are two calibration features on the device. Automatic self-calibration ensures the long-term stability without the need for any manual action from the user. This method of calibration assumes that the sensor is exposed to atmospheric CO2 concentrations of ~400ppm at least once per week. Manual recalibration can be carried out to restore the accuracy of the CO2 reading immediately; expose the device to fresh air by placing it outside or next to an open window. Press the CALIBRATE button to start the process and the display will change to show you it is under way. After a few minutes the process will finish and the display will resume showing the current readings. If there are any issues during the process, a warning screen will inform you. Ensure the supply of fresh air is adequate and try again. If your EL-IOT-CO2 ever needs you 

to carry out a manual calibration, it will prompt you to do so.

## **SENSOR ACCURACY AND INFORMATION** 

Typical and maximal tolerance for the relative humidity sensor at 25°C: 

Typical and maximal tolerance for the temperature sensor in °C: 

## **CO SENSOR 2** 

**Default conditions of 25°C, 50% RH and ambient pressure of 1013 mbar apply to values in the table below.** 

|**Parameter**|**Conditions**|**Value**|
|---|---|---|
|CO2measurement range1|-|0 to 40,000 ppm|
|CO2measurement accuracy2|400 to 2,000 ppm|±(50 ppm +5% of reading)|
|Repeatability|Typical|±10 ppm|
|Response time3|T63%, typical|60 s|
|Accuracy drift per year with<br>automatic self-calibration4|Typical|±(5 ppm +0.5% of reading)|



1  Exposure to CO2 concentrations smaller than 400 ppm can affect the accuracy of the sensor if the automatic self-calibration function is used. 

2 Deviation to a high-precision reference. Accuracy is fulfilled by >90% of the sensors after calibration. Rough handling or shipping reduces the accuracy of the sensor. Accuracy is restored with the automatic recalibration feature. Accuracy is based on tests with gas mixtures having a tolerance of ±1.5%. 

3 Time for achieving 63% of a respective step function under test conditions. Response times can depend on the operating environment in the final application. 

4 For proper automatic calibration the device has to be exposed to air with CO2 concentration 400 ppm regularly. Maximum accuracy drift per year estimated from stress tests is ± (5 ppm + 2 % of reading). Higher drift values may occur if the device is not handled according to the instructions. 

## **OPERATING CONDITIONS** 

The performance of the humidity sensor can be affected by long-term exposure to operating conditions at the extents of the logger’s range. The sensor shows best performance when operated within the recommended normal temperature and humidity range of 5 to 55°C and 20 to 80%RH, respectively. Long-term exposure to conditions outside the normal range, especially at high humidity, may temporarily offset the RH signal (e.g. +3%RH after 60h kept at >80%RH). After returning into the normal temperature and humidity range the sensor will slowly come back within the calibration state by itself. Prolonged exposure to extreme conditions may also accelerate ageing. 

When tracking changes in ambient conditions, the response time of the humidity sensor in your data logger is approximately 20 minutes to reach 90% of the reading. However, if you are measuring step changes in humidity (for example if calibrating the product) it is advised that you leave the unit for up to four hours to ensure that it has enough time to settle at the new level. 

It is worth remembering that the value of relative humidity is of course sensitive to temperature variation. As an example, at a relative humidity of ~90%RH at ambient temperature, a variation in temperature of 1°C will result in a change of up to -5%RH. Therefore when comparing multiple devices or calibrating them, any temperature variations must be considered. 

The humidity measuring element in the humidity data loggers can be contaminated through exposure to a variety of compounds. These products should not be kept in proximity to volatile chemicals such as solvents and other organic compounds. Generally speaking, if a material or compound emits a strong odour you should not keep your humidity data logger in close proximity to it. If you would like more information, please contact your local Lascar Electronics office. 

High levels of pollutants may cause permanent damage to the internal sensor.

This device is designed to be powered using the USB power supply provided. The logger does not lose its stored data readings when the power supply is disrupted. However, if the device has been logging, the logging process will stop and will not resume until the power supply is restored, and the device has reconnected to the WiFi network. 

To provide a back-up source of power in case the mains supply is lost, you can fit four AA batteries and the product will automatically switch to using them when needed. Use only AA 1.5V alkaline batteries. We recommend you replace the batteries annually.
