CO2 detector with Display, relay output and WIFI

Household carbon dioxide regulator for wall mounting. This regulator is capable of measuring the amount of carbon dioxide present in a closed environment by means of a precise sensor. In addition to carbon dioxide, the device also measures temperature and humidity in order to offer the user as much information as possible about the healthiness of the environment. The device also has a relay that is activated when the value in ppm of carbon dioxide is above the maximum threshold configured. To adapt the device to the needs of the user, the alarm threshold, which is 900ppm by default, can be set from a minimum of 700ppm to a maximum of 1500ppm. When an «alarm situation» is verified, in addition to activating the relay, the device sends repeated notifications via App to the user's smartphone, to inform them of the change in status; in this way, the user will be aware of what is happening at home. The regulator also includes a small screen on the front that allows to view the measured ppm values. It is possible to define a weekly operating program: for each day of the week, it is possible to define the hours at which the regulation of the CO2 concentration is active. The device has an infrared sensor inside that allows the device to work for 15 years. Specifications Trip threshold: internal DIP switch (900ppm by default) configurable before power-up (900ppm by default) CO2 sensor: 2-channel NDIR with an accuracy of ± 30ppm + 3% MV Relay: 10A at 250V AC / 10A at 30V DC, SPDT Intervention periods: weekly, configurable hour by hour by the user Display of detected temperature and humidity Alarm notifications through Appp 2.4 ~ 2.4835GHz IEEE 802.11b / g / n WiFi interface Power supply: 100V ~ 230V AC, 50/60 Hz and 12V DC Absorption: 5.29VA max. at 230V AC / 2.4W max. at 12V DC
