Bluetooth 5.0 Real-Time Temperature & Humidity Data Logger

This Bluetooth 5.0 real-time temperature and humidity data logger (Tzone TZ-BT06) is made for refrigerated trucks, cold rooms and pharmaceutical transport. It sends readings and alerts wirelessly to a smartphone up to 300 metres away, where you can view graphs and share PDF reports — so you can check conditions without opening the cargo or cold room. Default alarms are set for 2–8 °C and 40–60% RH, and it stores up to 32,000 readings.
