T1 Sensor
An ultra-low-profile sensor and data collector for loads that move. It records temperature and location and sends them over LTE-M.
Physical-world sensors
One catalog for SmartSense by Digi sensors. Category names below are links to headings on this page, so temperature, humidity, contact, and asset monitoring each have a URL you can open or share.
Devices from other manufacturers that have been certified for SmartSense stay on the third-party devices page. This catalog uses SmartSense by Digi product names only.
All Sensors
Selected category
The published SmartSense sensor lineup in this catalog: T1, Z, B2, and NIST probes for the Z Sensor.
Z Sensor
A battery-powered sensor for refrigerators, freezers, and ambient rooms. NIST-certified probes are available, and up to 24 connect to a gateway.
B2 Sensor
A 2-inch sensor with up to 4 years of battery life. It records temperature and humidity, detects a door opening, and stores readings until the gateway is back.
NIST probes
Twist-on probes for the Z Sensor, with a 2-year NIST calibration. Options cover temperature, humidity, an expanded range, and glycol simulation.
Humidity & Environment
Selected category
The B2 Sensor records temperature and humidity in the same device, with an NSF-grade enclosure.
B2 Sensor
A 2-inch sensor with up to 4 years of battery life. It records temperature and humidity, detects a door opening, and stores readings until the gateway is back.
Contact & Interaction
Selected category
The B2 Sensor includes door open and close detection, so a team can see that a refrigerator was opened and not only that the air warmed up.
B2 Sensor
A 2-inch sensor with up to 4 years of battery life. It records temperature and humidity, detects a door opening, and stores readings until the gateway is back.
Temperature
Selected category
T1, Z, and B2 all record temperature. T1 is built for assets that move. Z and B2 are placed in equipment and rooms. NIST probes extend the Z Sensor into cryogenic and other ranges.
T1 Sensor
An ultra-low-profile sensor and data collector for loads that move. It records temperature and location and sends them over LTE-M.
Z Sensor
A battery-powered sensor for refrigerators, freezers, and ambient rooms. NIST-certified probes are available, and up to 24 connect to a gateway.
B2 Sensor
A 2-inch sensor with up to 4 years of battery life. It records temperature and humidity, detects a door opening, and stores readings until the gateway is back.
NIST probes
Twist-on probes for the Z Sensor, with a 2-year NIST calibration. Options cover temperature, humidity, an expanded range, and glycol simulation.
Occupancy & Space
Selected category
SmartSense does not publish a separate occupancy sensor in this catalog. The Z Sensor is the device used in ambient rooms and other occupied spaces. Specialized occupancy hardware that has been certified for the platform is listed with third-party devices.
Z Sensor
A battery-powered sensor for refrigerators, freezers, and ambient rooms. NIST-certified probes are available, and up to 24 connect to a gateway.
Equipment & Asset
Selected category
The T1 Sensor is the in-motion asset monitor, with LTE-M and location. Z and B2 sensors mount in refrigeration and other equipment and report through a gateway.
T1 Sensor
An ultra-low-profile sensor and data collector for loads that move. It records temperature and location and sends them over LTE-M.
Z Sensor
A battery-powered sensor for refrigerators, freezers, and ambient rooms. NIST-certified probes are available, and up to 24 connect to a gateway.
B2 Sensor
A 2-inch sensor with up to 4 years of battery life. It records temperature and humidity, detects a door opening, and stores readings until the gateway is back.
How the sensors connect
Z and B2 sensors report through a SmartSense gateway. The T1 Sensor uses its own LTE-M connection. Gateway models and radios are on the connectivity page.
