CO2 sensor "Logtta"

CO2 sensor "Logtta"

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

Humans exhale CO2 through 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 with numbers and colors. Additionally, by adding a temperature and humidity sensor, it is also possible to display temperature and humidity. 【Features】 ■ Visualizes ventilation based on carbon dioxide (CO2) concentration ■ Displays ventilation status with numbers and colors - Green: Good ventilation - Yellow: Ventilation recommended - Red: Ventilation needed ■ By adding a temperature and humidity sensor, it is also possible to display temperature and humidity *For more details, please refer to the PDF document or feel free to contact us.

[IoT Textbook Series] Technical Overview of NDIR Method CO2 Sensors

[IoT Textbook Series] Technical Overview of NDIR Method CO2 Sensors

Customizable CO2 sensors! We will explain the utilization of "Sensor I/F LSI."

In light of the COVID-19 pandemic, what are the promising indicators of sensing technology utilizing IoT? Currently, the measurement of CO2 concentration using CO2 sensors is gaining attention. Humans breathe in oxygen and exhale carbon dioxide. In other words, CO2 concentration can be used as an indicator to measure whether people are densely packed together. This document explains the utilization of the "Sensor I/F LSI" currently under development by "Tele-Sentient" in constructing CO2 sensors. [Contents] ■ CO2 sensors as a notable indicator of social distance ■ CO2 sensor technology (NDIR method) ■ Tele-Sentient's Sensor I/F LSI *For more details, please refer to the PDF document or feel free to contact us.

[Column] What is a CO2 Sensor? Mechanism and Operating Principle

[Column] What is a CO2 Sensor? Mechanism and Operating Principle

What is a CO2 sensor? Introducing its mechanism and operating principle! / Leave the design of electrical and electronic circuits, and printed circuit boards to Nippo! /

A CO2 sensor is a device used to measure the concentration of carbon dioxide gas. It helps monitor the amount of CO2 gas released into the external environment and contributes to improving energy efficiency and ensuring indoor comfort. The general operating principles of CO2 sensors are mainly of two types: ◆ Chemical Sensor This method obtains gas concentration by utilizing "redox reactions." The electrical characteristics of the sensor (such as resistance and capacitance) change due to CO2 gas, and the concentration of CO2 gas is calculated from this change. ◆ NDIR: Non-Dispersive Infrared Method This method utilizes the characteristic that "molecules absorb infrared light at specific wavelengths." It measures how much light is absorbed and calculates the CO2 gas concentration based on that information. Currently, "NDIR-type CO2 sensors" are mainstream due to their high sensitivity and stability. Within NDIR-type CO2 sensors, there are different principles, including: - Single light source single wavelength method - Dual light source single wavelength method - Single light source dual wavelength method Nippo offers a wide range of services, from the design of electrical and electronic circuits to the design of printed circuit boards.

EnOcean CO₂ Sensor

EnOcean CO₂ Sensor

Efficiently avoid crowding, optimal for ventilation systems.

CO₂ sensor unit that measures temperature, humidity, and carbon dioxide concentration. It complies with the "Guidelines for the Selection of Carbon Dioxide Concentration Measuring Instruments" established by the Ministry of Economy, Trade and Industry. It uses solar cells for power generation and storage as the main power source, and is equipped with a backup battery. The backup battery can be used for about 10 years without replacement. *This is limited to use with a measurement interval of 15 minutes (depending on installation location/use environment). The measurement interval can be selected from 1 minute, 5 minutes, 10 minutes, 15 minutes, or a variable mode based on CO₂ concentration. In variable mode, the measurement interval is automatically adjusted according to the CO₂ concentration. In environments without people, such as at night, the measurement interval is extended, which is expected to reduce power consumption. 【Features】 ■ Data transmission via EnOcean wireless communication ■ Compliance with the guidelines established by the Ministry of Economy, Trade and Industry ■ Main power source is solar cell generation ■ Backup battery lasts about 10 years without replacement ■ Measurement intervals can be selected from 1 minute, 5 minutes, 10 minutes, 15 minutes, or variable mode
