EM21

Maintain compliance and product integrity by wirelessly monitoring temperature

With precise sensors and an easy-to-install wireless design, Samsara Environmental Monitor is ideal for ensuring food safety and product integrity during transportation, monitoring warehouse conditions, and other applications that rely on environmental data to ensure quality or maintain compliance.

Built to last and withstand harsh environments

IP67 and IP69k rated, the Environmental Monitor is dustproof and waterproof with the ability to withstand high temperature and high-pressure water. The design is as durable as it is sleek, with exceptional resilience to impact. The EM can run for 3+ years (subject to conditions) on a single-use, replaceable AA battery.

Class-leading electronics with multi-year battery life

With the industry's most advanced wireless technology, EMs transmit sensor data in real time to Samsara cellular gateways, enabling operators to see up-to-the-second sensor data over the web and to receive real-time alerts when conditions require their attention. When an EM is deployed out of a gateway's range, it logs data to on-board storage and automatically uploads the data the next time it comes near a gateway. Even with always-on wireless networking and data-logging, the EM runs for three years off of a single AA battery.

Scales from Small Operations to Thousands of Assets

Compact, affordable, and easy to use, Samsara EMs can quickly bring visibility to small operations without IT or engineering complexity. Yet Samsara's scalable cloud infrastructure and enterprise-grade security make the EM an ideal solution for monitoring large-scale operations.
