Designed for wireless data logging, this battery-powered logger records temperature, humidity and CO2 across three channels from internal sensors. It transfers readings to a phone or tablet over Bluetooth Low Energy, and shows live values on an LCD. Rated IP50 against dust, it works great for indoor environmental monitoring.

Onset's HOBO MX1102 CO2 logger makes it more convenient than ever to measure and record CO2 in buildings and other non-condensing environments. It measures CO2 from 0 to 5,000 parts per million (ppm) - and our free HOBOmobile app allows you to access data right from your mobile phone or tablet within a 100-foot range.
The MX1102 also features a USB port so it can be used with a computer running HOBOware Pro graphing and analysis software.
