Product Description
FAQ
Question: Does the device maintain a log of measurements over time? Answer: Yes. it does. The Apps has this UI to share you all the Data.
Question: Does an audible alarm sound if/when co2 levels become dangerous? Answer: Yes. we have three levels. If became dangerous then our devices will be make an audible sound.
Question: What is the accuracy of the CO2 and Humidity sensor? Answer: Accuracy: ± (50ppm + 5% reading value) Humidity Range:20-80%( ± 5% RH)Temperature Range: -10 ℃-40℃( ±1℃)
Question: Can the temp be set at Fahrenheit or Celsius?
Answer: Yes, both settings can be switched at will.
Question: Can you replace the battery yourself when it fails to charge?
Answer: This device does not have any visible screws in the case and I have not attempted to see if it snaps together to then be able to disassemble it to change the battery.
Question: What type of sensor is used in the detector?
Answer: Carbon dioxide gas sensor (hereinafter referred to as the sensor) is a general intelligent small sensor. As shown in Figure 1, it uses the principle of non dispersive infrared (NDIR) to detect CO2 in the air. It has the characteristics of good selectivity, no oxygen dependence and long service life; Built in temperature compensation; At the same time, it has serial port output and PWM output, which is convenient to use. The sensor is a high-performance sensor made by closely combining the mature infrared absorption gas detection technology with precision optical path design and excellent circuit design.
