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

EM-series monitors are designed for harsh operating environments. IP67-rated weatherproofing protects against splashes, spray, dust, and other environmental wear and tear – ideal for refrigerated trailers and food storage facilities subject to moisture and power-washing. The EM’s design is as durable as it is sleek, with exceptional resilience to impact.

HM-series monitors are designed for harsh operating environments. IP67-rating protects against splashes, spray, power washing, dust, and other environmental wear and tear. In addition, the HM11 has a durable design with exceptional resilience to impact.

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.

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.
