COVID-19 Measures CO2 Sensor (Crowd Notification Function)

It is a system that visualizes "sealing," "crowding," and "proximity" using a smartphone app.

In response to coronavirus measures that require avoiding the "three Cs" (closed spaces, crowded places, close-contact settings), this system visualizes "closed" using the Connect CO2 sensor and "crowded" and "close contact" using the Connect Cellular, all through a smartphone app. It is a device that enables the timing of ventilation using CO2 sensors in offices and meeting rooms, and measures smartphone users with Connect Cellular to visualize congestion levels. With reliable Japanese-made sensors, it ensures appropriate ventilation during the cold winter months. <Features> - Notifies about congestion and ventilation status - Easy installation with no construction required * No internet installation needed, and no wiring work associated with product installation - Communication fees and app usage fees are included in the initial cost, with no monthly payments required. - Equipped with highly reliable CO2 sensors (5 years of no maintenance) - The dedicated app displays congestion and ventilation status in real-time, with push notifications to alert smartphone users about ventilation timing - Power is also battery-operated (USB type-C), making management easy.

Agricultural CO2 sensor

CO2 sensor optimal for high temperature and high humidity environments.

This is a CO2 (carbon dioxide gas) sensor that measures the CO2 concentration in agricultural houses and storage warehouses for vegetables and fruits, and outputs an analog signal. It can be used in environments with high temperature, high humidity, and high ammonia concentration. Thanks to the automatic calibration function, tedious calibration is unnecessary for about five years.

CO2 sensor "Logtta"

Visualize ventilation with carbon dioxide (CO2) concentration! The ventilation status is displayed with numbers and colors!

Humans exhale CO2 by breathing, but in a sealed room, the CO2 concentration continues to increase. 'Logtta' visualizes ventilation based on carbon dioxide (CO2) concentration. It displays the ventilation status in numbers and colors. Additionally, by adding a temperature and humidity sensor, it becomes possible to display temperature and humidity as well. 【Features】 ■ Visualizes ventilation based on carbon dioxide (CO2) concentration ■ Displays ventilation status in numbers and colors - Green: Good ventilation - Yellow: Ventilation recommended - Red: Ventilation needed ■ By adding a temperature and humidity sensor, it also becomes possible to display temperature and humidity *For more details, please refer to the PDF document or feel free to contact us.
