a-Snap is an wireless sensor and datalogger which has been desinged especially for the needs of industry and cold chains. This small sized sensor is easy to assemble to measurement points. Distance in between sensors and receiver (a-Gate) can be up to 50 meters. Sensors have inbuildbattery which operates as long as five years. a-Snap has one inbuild temperature sensor, and possibility to add extra analog measurement (example: humidity sensor or pulse sensor) or extra temperature measurement. a-Snaps and a-Gate create an wireless monitoring network that is logged and sent to a-Log.net (A Measurement Data Portal for a-Lab Customers).
