JRI's LoRa SPY T1 data logger measures and records temperature and door openings. The SPY T1 has an internal sensor. For refrigerator temperature applications, the LoRa SPY T1 can be placed inside the refrigerator as a whole. This also allows door opening detection. The LoRa T1 is equipped with an internal light sensor. This eliminates the need for an external door contact for open/close detection. The logger is equipped with internal display and 3 alarm LEDs (green, blue, red). The LoRa SPY operates +/- 2 years on one lithium battery and has a memory for 10,000 measurement points. Optionally available with a COFRAC (primary ISO 17025 certificate) or traceable calibration.
