HEIMAN M420-107 High-Stable Indoor Smart Air Quality Monitor

Product Introduction

This high-stable indoor air quality monitor (hereinafter referred to as the monitor) is used for detecting the air quality in the indoor environment, including Co2, temperature, and humidity (temperature and humidity are optional features). As a multifunctional and smart air quality monitor, the monitor adopts an advanced sensor with high stability, small sensitivity drift, and long service life, free from calibration operation. Aided by advanced Zigbee wireless technology, the monitor can report environmental data in real-time stably and reliably. Once the monitor detects that the indoor air quality deteriorates excessively, the monitor will send alarm concentration information to the smart gateway, which will push the alarm messages to the mobile APP through the cloud server in real-time remotely. So the user could learn about the home air environment at any time, anywhere, and keep the home air quality at its best. The monitor is applicable in indoor environments such as residential houses, offices, etc.

Tips

Before using the monitor for the first time, please read the following instructions carefully and observe all warnings, even if you are familiar with the use of electronic devices.

1. Store and operate the monitor in a dry place out of direct sunlight to protect the components inside the monitor.
2. Before using the monitor for the first time, set it up in a well-ventilated environment. (such as a well-ventilated living room)
3. In order to make sure the monitor is more stable. it is recommended the monitor start to work after 24 hours of charging.
4. Do not cover the monitor and in particular do not block the air inlets while the monitor is active.
5. Keep water and other liquids away from the monitor as it is not waterproof.
6. Do not insert sharp, flammable, or metallic objects into the air inlets as this can result in an electric shock or burns.
7. Power should be supplied via the micro-USB cable and the AC adapter; the internal, built-in battery is only used for emergency power supply.
8. 1f If the device has been dropped or otherwise damaged, it may not be used anymore.

ABC Calibration

For ABC to work properly, the device must continuously monitor CO2 levels for at least 7 days (power on). During that time, it will record the lowest C02 level and set that as the 400 ppm baseline for future readings. Therefore, it is critical when using ABC calibration that the device is exposed to fresh air at least once during the 7 days If’s not suitable to implement ABC in a close area with a higher CO2 level all the time.

Quick Setting For Network Configuration

How to connect the monitor

Connect the USB cable to the power adapter, and insert the adapter into the socket to power on the monitor. Make sure that the mobile phone is connected to WiFi (and the WiFi is connected to the available network), open the APP on your mobile phone, register an account and log in.
