Description

Imminent danger of CO poisoning is a growing concern in the care for elderly, child and immuno-compromised individuals. Senseit’s wireless sensor platform and online monitoring software provide a very affordable, simple-to-setup, feature rich solution that helps meet the growing demand of legislative and public concerns regarding the monitoring of gas leaks and emissions.

The mems based wireless carbon monoxide sensor allows you to monitor the level of carbon monoxide (CO) gas in the surrounding air. Senseit wireless CO sensors have a small footprint and low cost but boast industry leading, premium performance specifications and are the longest lifetime sensors in the industry and the only CO sensor on the market powered by a coin cell battery (battery lasts over a year at 1 hour heartbeat). User customization allows you to set the frequency of readings and the ability to set customized alerts via SMS text or email when the sensor detects CO levels outside of the user’s defined safe levels.

The standard version of this sensor is powered by two replaceable 1.5 V AA sized batteries (included with purchase). This sensor is also available with a line power option. The line powered version of this sensor has a barrel power connector allowing it to be powered by a standard 3.0 – 3.6 V power supply (Included with Line Power option upgrade). The line powered version also uses two standard 1.5 V AA batteries as backup for uninterrupted operation in the event of line power outage.

Power options must be selected at time of purchase, as the internal hardware of the sensor must be changed to support the selected power requirements.
