Wireless Environmental Monitor

Wireless Environmental Monitor

The EM11 environmental monitor is a datalogging wireless monitor capturing temperature, humidity, and shock.

List price: $99 plus $5/mo license (all-inclusive license includes maintenance, support, cloud software, and cellular data, if applicable. Volume purchase and multi-year license term discounts available.)

Monitor Temperature, Humidity, and Shock

Samsara environmental monitors include precise temperature, humidity, and shock sensors in a compact and integrated package, making them ideal for a variety of environmental and asset monitoring applications from food and drug safety to life sciences and protecting high-value goods.

All-Wireless Design with Multi-Year Battery

Samsara environmental monitors use state of the art low-power circuitry and RF communication, enabling them to transmit sensor data wirelessly, in real time, with a compact battery that lasts over three years. An all-wireless design facilitates use in distributed and mobile environments, from the inside of a refrigerated vehicle to walk-in freezers and even inside packaged goods.

Real-Time and Datalogging Capture

When in wireless range of a Samsara IoT Gateway, EMs transmit sensor data in real time, providing operators with a live view of all of their connected assets. For the times when a gateway is not available, e.g. when an asset is handled by a third party, EMs log sensor data to on-board storage, uploading the historical data when a gateway connection is established.

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.
