miniTemp Logger

Temperature Mapping

Our miniTemp logger is a Bluetooth wireless temperature sensor in a miniaturized package ideal for high-volume temperature mapping.

It comes with either an internal or external temperature probe, with a variety of external probe options available to suit the needs of your industry. These include standard bullet probes (for medium to fast response), buffered glycose probes (for slow response), or needle probes (for precise insertion).

The onboard SensorGraph processes incoming sensor data to produce high level events available in real time over Bluetooth to a smart phone or via gateways to a cloud messaging system.

Historical data is uploaded to the cloud where our analytics package lets you analyze sensor-by-sensor, area-by-area, and across your entire operation.
