The Mill Sense is a smart indoor air quality monitor developed by Mill in Norway, designed to provide users with real-time insights into their indoor climate. It connects to a home's WiFi network and integrates with the MillNorway app, allowing users to monitor various environmental factors directly from their mobile phone. The device focuses on creating a healthier and more comfortable indoor environment by measuring key air quality parameters and offering actionable recommendations.
One of the primary functions of the Mill Sense is to measure humidity. High humidity levels can contribute to mold growth, which is detrimental to health, potentially causing asthma and allergies. The device helps users maintain a recommended humidity range of 30-60%, suggesting that good ventilation during activities like showering, drying clothes, and cooking is crucial. For persistent issues, a humidifier or dehumidifier might be recommended. The Mill Sense provides accurate relative humidity readings, helping users prevent the adverse effects of excessive moisture.
The device also monitors Total Volatile Organic Compounds (TVOCs), which are airborne chemicals and toxins emitted from everyday items such as paints, furniture, and cleaning products. High concentrations of TVOCs can cause irritations in the eyes, nose, and throat, and prolonged exposure can lead to more severe damage to organs like the liver and kidneys. The Mill Sense helps users keep TVOC levels below the recommended threshold of 220 ppb. If levels are high, an air purifier is suggested to improve air quality. The device specifically measures various VOCs, including alcohols, aldehydes, ketones, organic acids, amines, and aliphatic and aromatic hydrocarbons, providing a comprehensive overview of potential indoor air pollutants.
Temperature is another crucial measurement provided by the Mill Sense. Maintaining a consistent temperature across all rooms is vital for a healthy indoor climate. The device helps users avoid common mistakes like completely turning off heat in unused rooms, which, when combined with humidity, can lead to mold growth. Temperature also impacts comfort levels and can influence susceptibility to colds or flu. For enhanced control, the Mill Sense can connect to Mill WiFi heaters (excluding generation 1 heaters) to provide more precise temperature regulation, automatically adjusting to daily routines and maintaining a recommended temperature range of 18-25°C. The temperature sensor offers high accuracy, ensuring reliable readings.
Additionally, the Mill Sense calculates equivalent Carbon Dioxide (eCO2) levels based on VOC measurements. While this calculation makes assumptions about the proportion of VOCs attributable to CO2, it serves as an indicator of ventilation needs. Moderate to high eCO2 levels can cause headaches and fatigue, with very high concentrations potentially leading to nausea, dizziness, vomiting, and even loss of consciousness. The device emphasizes the importance of good and regular ventilation to maintain eCO2 levels below 1200 ppm, promoting a well-ventilated and healthy living space.
For usage features, the Mill Sense is designed for indoor use only. Users should avoid direct exposure to sunlight and heat sources, and ensure the device is placed away from vents and windows to ensure accurate readings. The device is not meant to be disassembled; if issues arise, users are advised to contact their dealer or visit millnorway.com. Cleaning the device requires a dry cloth.
Before starting, users need to ensure their smartphone has a working internet connection, that any firewalls or VPNs are disabled to allow communication with the server, and that Bluetooth is enabled for initial setup. The setup process involves downloading the MillNorway App, creating an account, and following the in-app instructions to connect the device. It's important to note that the sensors require 72 hours for full calibration and accuracy after initial setup.
The Mill Sense features an indicator light, an ON/OFF button, a backside with a magnet for easy placement, a charging port, and an air vent. It comes with a wall-bracket with a magnet and a USB type C charging cable. During charging, the app will not display sensor measurements as the heat generated can affect accuracy. Once fully charged, measurements will reappear, and the charging cable can remain connected if preferred.
The device can be placed on a flat surface or attached to a wall using the provided wall-bracket with double-sided tape. A key interactive feature is the ability to press the button on the Mill Sense to understand current air quality levels through color-coded feedback:
The Mill Sense offers integrations to enhance its functionality. It can automatically calibrate and control Mill WiFi heaters, using its accurate temperature readings to provide more precise indoor temperature regulation. Sensor data from the Mill Sense is also available through an open REST API, allowing for custom integrations. Furthermore, the device can be added to the Tibber app, a digital energy company, to view sensor data and help users control their total power consumption with full price transparency.
Maintenance features include full customizability through the MillNorway app. Users can customize sensor trigger ranges for the button feedback and adjust how often the Mill Sense uploads new sensor data.
For troubleshooting, if the device needs to be reset, holding the button for 3 seconds will reset the connection, restore factory settings, delete the device from the cloud and the user's account, and put it into deep sleep. If the device is not showing accurate temperature or humidity, users should ensure it is not near a heat or humidity source, as the temperature and humidity sensors are pre-calibrated.
The Mill Sense is backed by a 2-year warranty, covering malfunctions under normal usage conditions, provided a purchase receipt is presented. For environmental responsibility, the device is marked with a symbol indicating it should not be disposed of with household waste. Instead, it should be delivered to a recycling service for electrical and electronic equipment to prevent harm to the environment. For efficient recycling, users can separate the battery from the product and dispose of it at a dedicated container for lithium batteries. Instructions for battery removal involve using a straight screwdriver to disassemble the front shell, a cross screwdriver to remove four screws, removing the PCB by hand, and then removing and disposing of the battery.
