samsara 010-0031 Environmental Monitor
OVERVIEW
- The EM31 is a wireless, waterproof, data-logging temperature sensor that surfaces data to the Samsara cloud via Samsara vehicles or Asset Gateways. The EM31 can also connect to accessory probes (ACC-EM-P1) for a wider range of temperature applications.
- With precise sensors and an easy-to-install wireless design, Samsara environmental 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.
HIGHLIGHTS
- Wireless: Wirelessly monitors temperature with proprietary 2.4 GHz when connected to a compatible Samsara-powered gateway.
- Waterproof: Waterproof, ruggedized design with LCD
- Battery Powered: Runs for 3+ years (subject to conditions) on a single-user replaceable AA battery
