5. Placement For long-term use, the sensor should be connected to a power supply, as battery power alone can only last for about 7 days. Therefore, battery power is used as a backup power source. The particle sensor has a built in fan inside： It will be turned on/off regularly when measurement is needed. -

Page 32: What Types Of Ndir Sensors Exist And How Do They Work
Note: The WH46D sensor data can be only viewed on the Live Data interface since it doesn’t support uploads to weather underground. If you choose to upload the data to our weather server: https://www.ecowitt.net, you can view the live data/history graph and download the records on the website. - Page 33 Instead, the light produced by the emitter is shown through a non-dispersive band-pass filter, allowing only the infrared wavelengths of interest to pass. These characteristics give the sensors their classification: Non-dispersive Infra-red. Transmissive NDIR: These NDIR sensors typically feature an IR emitter and an optical detector, such as a photodiode, at opposite ends of a specially designed optical cavity.
- Page 34 NDIR CO₂ sensors leverage infra-red absorption at 4.2 µm wavelength without the use of dispersive optical elements. Absorption spectra of common trace gases (HITRAN2016 molecular spectroscopic database)
- Page 35 Note that this reference value heavily depends on precise positioning of IR emitter and photodetector, as well as the emission properties of the IR source and the optical cavity. Mechanical and thermal stresses acting on the measurement chamber can thus significantly falsify CO₂...
- Page 36 Photoacoustic NDIR: In contrast to transmissive NDIR sensors, photoacoustic NDIR sensors detect the amount of energy that is absorbed by CO₂ molecules. When pulsing the infra-red emitter, CO₂ molecules absorb infra-red light periodically. This causes additional molecular vibration resulting in a pressure wave inside the measurement chamber.
- Page 37 A microphone inside the gas chamber measures this, from which the CO₂ concentration can then be calculated. Photoacoustic NDIR sensing allows for much greater miniaturization of the measurement chamber. Furthermore, as sound waves are omnidirectional, relative positioning of emitter and microphone is unconstrained.

Page 38: Troubleshooting For Inaccurate Readings
13. Troubleshooting for inaccurate readings 13.1 Auto Calibration Operation: If you find that the readings of the carbon dioxide sensor are inaccurate after a period of use, please place the device in a well-ventilated location for at least one day. Make sure there are no other sources of pollution around, and ensure that the sensor surface is not obstructed or affected by external interference. - Page 39 current PPM reading and 400 target reading digits will be flashing. You can press the “SET” button to choose between 400~420ppm, and then press "°C/°F" to continue, leaving the device untouched for 5 minutes until the calibration routine is completed and returns to normal display mode.
- Page 40 If calibration is triggered by mistake, hold “SET” to cancel and exit. The target readings enable to set 400 to 1990. Figure 4 Calibrating After calibration, the screen will automatically return to the standard screen. Otherwise, the animation will be...

Page 42: Care +Maintenance
14. CARE +MAINTENANCE When batteries of different brand or type are used together, or new and old batteries are used together, some batteries may be over-discharged due to a difference of voltage or capacity. This can result in venting, leakage, and rupture and may cause personal injury. - Page 43 • Remove batteries from product during periods of non- use. Battery leakage can cause corrosion and damage to this product. • Remove used batteries promptly. • For recycling and disposal of batteries, and to protect the environment, please check the internet or your local phone directory for local recycling centers and/or follow local government regulations.
