[CO2 Sensor × Ventilation Measures] CO2 Temperature and Humidity Monitoring Set <No Wiring Required!>

ISAI Corporation has developed a high-function version of a carbon dioxide concentration measuring device, the "Indoor Environment Measurement Monitoring Device Miru-kun PRO <WD100-ENV-LCD>", which contributes to infection control and productivity improvement, and will begin sales on January 21, 2022. This product displays the measured values of indoor temperature, humidity, and carbon dioxide (CO2) concentration on a large LCD screen, while visualizing the environmental conditions with three colors of light according to the levels. It notifies users via email or alerts when ventilation is needed. Data is sent to a higher level using LoRa, a representative wireless communication method of LPWA, for visualization and analysis. A compact version model without an LCD <WD100-ENV> will also be released simultaneously. Both models allow for quick startup from installation, enabling measurement, monitoring, and countermeasures to begin in a short period. When combined with an additional contact input/output unit, it is also possible to coordinate and control ventilation systems. Up to 32 child units can be connected to one main unit, and the communication between the measuring unit and the main unit uses LoRa wireless communication, covering areas and obstacles that Wi-Fi or Bluetooth cannot reach. It is also ideal for environmental monitoring in large factories and facilities.

The DN-1600W series, which specializes the interface for Wi-Fi-only functionality, allows for the easy construction of warning and alarm systems in a Wi-Fi environment without the need for LAN installation. It can be used in various locations such as offices, server rooms, medical and caregiving sites, as well as in conference rooms and management offices where personnel are not always present. Operating as a Wi-Fi client, it lights up or flashes lamps based on commands sent via applications (HTTP, MQTT) and activates the built-in buzzer to quickly inform surrounding workers and stakeholders of the "status." The newly announced DN-1600WD is a model equipped with DI (dry contact signal input) functionality, which has been added to the already available DN-1600W. It directly controls lamps and buzzers from external device contact signals. Many devices and sensors can output state changes as contact signals, and by connecting this signal to the contact input terminals of the DN-1600WD, it can easily be added as a reporting device. For example, it can notify of "state changes (abnormalities in equipment or temperature, intrusion of individuals, etc.)" when combined with motion sensors, security cameras, temperature sensors, or door sensors.

ISAI Corporation has developed a compact, palm-sized warning light called "Doko Demo Keiko-chan," which takes into account the changes in lifestyle such as "recent work styles" and "new living standards" from the Keiko-chan series. Following the USB-compatible model, the first Wi-Fi-only model, "DN-1600W," will be available for sale starting December 9, 2020. This warning light works in conjunction with applications and service programs on PCs and servers, combining buzzer sounds and lamp flashing via Wi-Fi to quickly inform surrounding workers and stakeholders of the "status." For example, when linked with Meru Maru-kun, it will notify the Doko Demo Keiko-chan installed on the same network with light and sound when a specific important email that should not be missed is received. It contributes to "awareness" in various settings such as offices, schools, tutoring centers, and commercial facilities.
