Overview:
1 Power supply: Micro USB 5V/1A 2. Use metal oxide semiconductor SGP30 gas sensor 3. Function: CO2, TVOC detection 4. No calibration required 5. Accuracy: ±25% of reading 6. Detection range: TVOC: 0~10000ppb, CO2: 400~10000ppm 7. Update data every 2 seconds
Display instructions:
CO2: 400~600ppm Good (very good) 601~1000ppm OK (Yes) 1000~2000ppm Bad (bad) More than 2000ppm So Bad (very bad) The concentration of CO2 and the physiological reaction of the human body are as follows (for reference only): ? ? ? 350~450ppm is the same as general outdoor environment; ? ? ?350~1000ppm fresh air, smooth breathing; ? ? ?1000~2000ppm I feel the air is muddy and start to feel drowsy; ? ? ?2000~5000ppm headache, lethargy, sluggishness, inability to concentrate, rapid heartbeat, mild nausea; ? More than 5000ppm may cause severe hypoxia, causing permanent brain damage, coma, and even death.
TVOC (Total Volatile Organic Compounds): 0~500ppb Good (very good) 501~600ppb OK (Yes) Greater than 600ppb Bad (bad)
Precautions:
1. It takes about 16 seconds to boot up. 2. The sensor is a sensitive gas sensor, please do not approach the human body (human breathing), do not place it on odorous objects surface. 3. Do not place and use in an environment where the gas exceeds the range. 4. If it has not been powered on for a long time (more than 7 days), it should be used after 24 hours of continuous power on. 5. The effect is better after 1 hour of continuous power on for the first time. 6. When changing the environment, it is better to observe the data after standing still for 10 minutes. 7. Sensitive sensors, it is normal to detect data floating. 8. Due to accuracy limitations and the influence of ambient gas, the test results are for reference only.
